2.—Anchors and plates of S. Suvenuaa, from Quatrefages, showing thearmed or spinous character of the anchor at its convex border,and the plate with six holes surrounding the central aperture, asin inhccrens; but the thick plain borders distinguish it.

3.—Plate, compounded of the various published figures of Synapta—Hogg, Carpenter, ' Micrograpbic Dictionary,' Quatrefages. Thewhole animal is Hogg's figure of Chirodota from Forbes, calledSynapta by Hogg; the oral tentacles are imaginary developmentsof S. digituta.

C, in this figure, is an anchor-plate of S. Sarniensis, for com-parison.

4.—Anchors and plates of S. iii/iarens, given by Professor WyvilleThompson in the ' Microscopical Quarterly Journal.' (Comparewith fig. 7.)

7.—Anchors and plates of S. inhcerens, as prepared from a specimenforwarded to the author by Professor Thompson, of Belfast; sixholes surrounding the central aperture ; margin of plate smooth ;apertures crenated.

8.—Anchors and plates in situ skin of Synapta hi-dcnttda, obtainedfrom China. Anchor-head bifid at each extremity ; plate, six holesaround central aperture; apertures oval; margins smooth.

9.—Anchors and plates of S. Sarniensis, seen by reflected light; thewell-formed arch apparent; the cup-shaped appearance of plate ;the reflected arms of the anchors; the seven holes around thecentral'aperture; rounded holes, crenated edges, and margin.

10.—Photographs taken by the Rev. J. Whiting, of Clifton, also fromS. Sarniensis; some plates monstrous in this slide; seven holes arecentral in the normal.

11.—Various plates and anchors from Synapta Sarniensis, by transparentlight; seven holes around central aperture; margins crenated;apertures roundish; margin of plate crenated; arch dimly seen.

C and d, two plates of <S". inhcErerm occurring by accident in theslide. The animal found in the same bed with S- Sarniensis.

DESCRIPTION OF PLATE IX,

Illustrating Dr. E. Perceval Wright's paper on Hartea.

Fig.1.—Hartea elegdns, fully expanded rind greatly enlarged; '«', basal por-

tion, thickly studded with spicula {vide fig. 4 ) ; 'V, the swollen

bases of the tentacles, crowded with elongated spicula {vide fig. 3).

i.-^-'Ihe same, twice the size of life, tentacles contracted.

3.—Spiculum from base of tentacle.

4.^Spiculum from base of the polype1,

N.B.—The shell represented in fig. i is drawn from the imagination of

the artist, as, in t,he examination of the specimens, they became detached from

the Cardium Norvegicum.
