Capsella elongata. Caps, testa oblongo-transversd, 

 compresso-convexd, suhaquilaterali, irregulariter ru-

Psammobia elongata, Lamarck, Auim. sans vert. vol. vi. 

 p. 176. 



Hob. Philippine Islands ; Cuming. 



This Lamarckian species of Psammobia may be regarded 



as the type of the genus under consideration, all the species 



of which, it will be seen, are well distinguished from the 



true Psammobia. 



Of solid roughly striated growth and compressly ob- 

 long-square form, tinged with fulvous-purple. 



Species 5. (Mus. Cuming.) 



Capsella solida. Caps, testa elotigato-transversd, ver- 

 sus marginem compressd, crassiuscidd, irregulariter 

 rugoso-striatd, subcequilaterali, sordide alba, ad um- 

 hones fulvo-purpurascente, epidermide fibrosd prope 

 marginem indutd, latere antico rotundato, postico late 

 truncato, angulum obtusum formante. 



The solid Capsella. Shell elongately transverse, com- 

 pressed towards the margin, rather thick, irregularly 

 roughly striated, nearly equilateral, dull white, ful- 

 vous-purple at the umboes, covered near the margin 

 with a fibrous epidermis, anterior side rounded, pos- 

 terior broadly truncated, forming an obtuse angle. 



Hab. Malacca. 



Species 6. (Mus. Cuming.) 



Capsella violacea. Caps, testa elongato-transversd, 

 gibbosiusculd, viueqnilaterali, tenuistriatd, intense pur- 

 pureo-violaced, epidermide fibrosa prope marginem in- 

 dutd, latere antico breviore, subattennaio-rotundato, 

 postico late oblique truncato, angulum obtusissimum 

 formante. 



The violet Capsella. Shell elongately transverse, 

 rather gibbous, inequilateral, finely striated, deep 

 purjjle-violet, covered with a fibrous epidermis near 

 the margin, anterior side the shorter, rather attenu- 

 ately rounded, posterior broadly obliquely truncated, 

 forming a very obtuse angle. 



Hab. Bay of Manila ; Cuming. 



A rather solid gibbous shell, of a characteristic deep 



purple-violet colour, covered near the margin with a very 



decided fibrous epidermis. 



Species 7. (Mus. Cuming.) 



Capsella radiata. Caps, testa elongato-tra/isversd, sub- 

 aiiguitd, postice gihbosd, subaiquilaterali, tenui, subti- 

 lissirne striata, Jlavescente-rosed, translucidd, umboni- 

 bus vivide roseis, latere antico attenuato-rotundato, 

 postico subampliter oblique truncato. 



The rayed Capsella. Shell elongately transverse, 

 rather narrow, gibbous posteriorly, nearly equilateral, 

 thin, very finely striated, yellowish-rose, translucid, 

 umboes deep rose, anterior side attenuately rounded, 

 posterior side rather largely obliquely truncated. 



Deshayes, Pro. Zool. Soc. 1854, p. 348. 



Hab. Orion, Bay of Manila ; Cumiug. 



An extremely delicate semi-transparent rose-tinted shell, 



much more largely angularly developed on the posterior 



than on the anterior side.
