IKillary Harbour. In 1892, Mr. E. W. L. olt (7) mentionis a few Coelenterates in his lnotes on the invertebrates collected in the course of the scienitific investigation of the fishinig-grouinds off the west of Irelanid carried oln by the

Royal DIublin Society in 1890-1891. For some years Dr. J. E. Duierden worlked especially at Irish Hydroicls, and added many interestinig species to

the Irish faunia. Of the species mentiolned by him in papers published durinig

the years 1893-1897, ninie are reported from Blacksod Bay. Of these

Tubiclava cornucopiae was nlew to the Irish coast, anid several of the other

species were rare. In the list of Irish Coclelterates published in 1905 (8) three more species were recorded for the district.

Sixty species of Coelenterates resulted from the work done during the Clare Islanid Survey. With the exception of a new species of sea-anemolne

described by Professor Carlaren, none of the species is niew to Irelalnd, buit

several have previously been found onily once or twice off the Irish coast, and

over forty are now notecl for the first time for Co. Mayo. The mnedlusoid formis of

the Hydrome,dusae were, unifortunately, untouched drinLg the presenit Srvey,

but the other Coeleuiterate groups are representecl. Species of Aleyonaria,

Siphoinophora, and Ctenophora are here recorded for the first time for the

district. Amonig tim Scyphomedtusae Deastrurn cyathiforme has only once

before been taken off the Irish coast. The Hydroids were not found in great nunmbers between tide-marks, witl

the exception of one or two species which occurred locally in abundance.

For example, Clava sqtamata, growing on Ascophyllumit nodosm?2, was seen in the greatest profulsion off the sheltered shores of the islands in Westport

Bay, and Tubularia intdivisa was found by Mr. Praeger spreadingr in large

sheets over the walls of the "Seal Caves," to the north of Light-house Cove, Clare Island. Tufts of the latter species occurred in the pools at the end of one of these caves, in compalny with Coryne vaginata and two specimnenis of C(aryophyllia Smithi, which were fully expanded when founid. The floor of one of the pools was completely covered by Corynactts viridis and many brightly coloured sponges, while very large specimens of Sacgartia venusta grew in the crevices of the rocks.

Sertudariacut mYLila was the only Calyptoblastic Hydroid that occurred in abunldance between tide-marks.

Hydra vmlgaris was the only fresh-water species that was obtained. It was fouLnd in great numbers in the brackish pool on Clare Island and in several of the lakes on the mainland.

Sea-anemones grew in great abundance, though not in great variety as regards numbers of species, in the rock-pools of Clare Islanid, Achill Island, and Old Head. They were not numerous along the shores of Westport Bay

and Blacksod Bay, where the rock-pools are few, and where the shores are strewn for the most part with large Fucus-covered stones. Only a few species, chiefly Actinia equina, Anemonia sulcata, and Urticiuca felina, were found between tide-marks in these two bays ; the anemones, such as Sagartia venusta, S. miniata, S. nivea, and Corynactis viridis, so characteristic of the rock-pools of Olare Island, being extrenmely rare or entirely absent.

Caryophyllia Srnithi and Sphenotrochus Wrighti were the only two members of the Madreporaria taken during the Survey.

I ain greatly indebted to Professor Carlgren, of Stockholm, for his kindrness in naming several specimens of sea-anemones, particularly those belonging to the genera Cerianthus and Halcampa, and for the preliminary description of his new species of Halcampoides, to which one of the Irish specimens belongs.

SCYPHOMEDUSAE. STAUROMEDUSAE.

Depastrum cyathiforme Gosse.-East slhore of Clare Island, betweeni tide inarlcs, six specilmens (collectecl by G. P. Farran), and in a rock-pool lnear

the liarboutr, three specimelis (collected by R. LI. Praeger).

This species has only once before been recorded for the Irish coast.

It was collected in Dalkey Sotind, Co. Dulblin.

Halielystus auricula (Rathke).-East shore of Clare Island, between tide mnarks, five specimens; off Clare Island light-house, 7 fms. (one specimeni).

Lucernaria campanulata Lamnourotu.-East shore of Clare Islanid, between

tide-marks (two specimelns), and off the harbour, 4 fms. (collected by N.

Colgan); Blacksod Bay, between tide-mnarkcs and in 3-5 fms. (three

specimens). DISCOMEDUSAB.

Pelagia perla (Slabber).-Mauy specimens were fotund washed up along the

soutih shore of Clare Island (July, 1909). Large shoals of this species

were seen by Mr. Praeger and Mr. Colgan off Clare Island light-house.

Washed up on Dugort strand, Achill Island; on the Atlantic side of The

Mullet; and in Blacksod Bay.

The only Irish records for this species are for the south-west coast ancd Yalencia Harbour.

Chxysaora isosceles (Linn.).-Very common throughout the district and often fouind in large numbers washed up on sandy beaches.

Aurelia aarita (Linn.)n-Very common throughout the district. On one occasion jelly-fish, belonginga most probably to this species,

were seen in immense niimbers off the north-west coast of Clare Island.

They formed dense shoals several hundred feet in length, and were

clearly seen from the cliffs, from a point about 600 feet above the water.

In a photograph taken at this height (see Clare Island Survey, Part 20,

Plate II), the shoals of jelly-fish appear as faint grey strealks between the

base of the cliffs and the line of white foam breaking on the outlying rocks.

Epizoanthus inorustatus (Diibein and Koren).-Cle,w Bay (5). Halcampa chrysanthellum (Peaclh) ?-Elly Bay, Blacksod Bay; one specimnen

found in sanid when slhore-collecting. Irofessor Carlgren notes that the single specimen is very much contracted, and that it was imiipossible to

make good sections of the splhincter. Nor was it possible to decide if the sphincter was inesogloeal or endoderrnal; but the presence of numerous spirocysts in the capituilar region, and the structure of the suckers on the scapus, indicate that this specimeni is a Halcampa.

Two small specimenis which appear to be larvae of Halcampa were

dredged in 21 fims. off Clare Island light-house. Professor Carigren prepared transverse sections of one of these specimens, and writess:-" In

the oral part only ten mesenteries are present, the eight Edwardsia

meseniteries arid the fifth couple. Of these, the fifth couple is not yet up

to the stomodaeum, and its longitudinal muscles are comparatively feeble.

Of the sixth couple, which is present in the more aboral part of the body,

only the parietal region is developed. Here also two pairs of mesenteries

of the second cycle are present in the dorsal exocoels. The siphonoglyphes

are feeble. As one distinct, deep siphonoglyphe is absent, the specimen

cannot be a Peachia or an Eloactis. The presence of numerous spirocysts

in the oral part of the column, the grouping of the tentacles and of the

mesenteries, and the structure of the musculature in the mesenteries are

characters that suggest a Halcampa. However, I mtust add that I have

not examined the sphincter, nor have I seen distinct suckers on the

column."

Halcampoides elongatus Carlgren neiv species.-21 miles E.9l N. of Clare

Island light-house, 21 fms. Dredged by the " Helga."

Professor Carlgren has kcindly sent the following preliminary description of this species:

"Dimensions in contracted state: Lengtl, 3 cm.; breadth in the distal part, 0 7 cm. Colour in spirit Capitulum oclire, lighiter orally.

"D escription.--The single specimen is very contracted and all the

tentacles are turned in, so that no tentacles are visible from the disc. The

species differs from other species of Halcampoides by the much elongated but thin parietal muscles, as seen in cross-sections. The longitudilnal muscles are not so strong as in Halcampoides cbyssorum, but it is probable that the mesogloea-ridges increase in number with the years."

Professor Carlgren believes that this species is the same as onie

whiich he has dredged off the coast of Bohuslhin, Swedeln. He intends to publish a detailed description of the species in an account of the northern and arctic invertebrates in the Swedislh State Museum (Riks Museum), which is in cotrse of preparation.
