CYPE^A.— Plate XXII. 



Hah. Isle of Annaa, Pacific Ocean (on tlie reefs) ; Cuming. 



This extremely delicate and gracefid species appears to 

 have been kiio-mi to 'old Humphi-ey' as 'The pearl-porcelain 

 Cowi-ey'. The pecidiarity in its style of pauitiag is that 

 there are two distinct systems of spots of different magni- 

 tude, wliich are not eneu'cled with rino-s.

The ash Cowrey. Shell ovately ventricose, sometimes 

 oblong, sides rather thickened, teeth rather short ; 

 back ash-brown, tlu-ee-banded, sometimes longitudi- 

 nally painted with jet black oblong dots, sides flesh- 

 tinged, peculiarly confusedly stained with numerous 

 jet black dots, base yellowish, interstices between 

 the teeth pinkish flesh-colom\

Hah. West Indies (imder stones) ; Giulding. 



The black-dotted painting which so strongly character- 

 this species is perhaps less constant than the pinkish flesh- 

 colouring between the coliuneUar teeth, of which I have 

 invariably noticed indications where the fii'st-mentioned 

 chai-acter was wanting.

Beck's Cowrey. Shell somewhat pjTiformly ovate, side 

 slightly margined and pitted, extremities a Uttl 

 beaked and reflexed, apertiu'e rather flexuous, teetl 

 small, rather strong ; fulvous ycUow, back orna 

 mented with large and small white eyes, of which th 

 large are pupilled with chesnut, sides dotted -witl 

 chesnut, linearly dotted at the outer teeth ^^ith ches 

 nut brown. 



Gaskoin, Pro. Zool. Soc. 18.35. 



The C. Beckii approximates very closely in form to th 

 C. margarita, and like that species it has two distinct size 

 of white eyes ; it differs, however, in ha\'ing the range c 

 larger spots pupilled wdth chesnut brown, the sides dottei 

 with chesnut-brown, and the outer teeth each marked o: 

 the base with a chesnut-brown linear dot. In a specime 

 kindly remitted to me by M. Deshayes the form is les 

 pear-shaped and the extremities more obtuse. 



Species 126. (Mus. Cuming.) 



Cypr^a ireorata. Cijpr. testa ovato-oblongd, lateribi 

 submarginatis, basi depresso-pland ; dorso pallide pm 

 pureo-ccerulesceiite, obscure fasciato, punctis Jimnerost 

 fuho-fuscis, latera versus satiiratioribus, copiose ai 

 sperso, basi albidd, immaculatd. 



The bedewed Cowrey. Shell ovately oblong, side 

 slightly margined, base depressly flattened ; bac 

 pale purple-blue, obscm-ely banded, copiously sprinl 

 led mth fidvous brown spots which are darker in c( 

 lorn- towards the sides, base whitish, unspotted.

It would be difficidt to confound tliis with any oth( 

 species, so peculiar is it both in fonn and style of c( 

 lourin?.
