Species 108. (Mus. Cuming.) 



CyPKiEA VESICULAUIS. Cijpr. testd globoso-uijlatd, tenui, 

 subpellucidd, striis subdUbus eleoatis, Mc ilUc bifiircatis, 

 creberrime ortiatd ; aperturd ampld, lata, labro deidi- 

 culato, dentieidis subdktantibus ; pallide pellucido- 

 earned. 



The vesiculated Cowrey. Shell globosely inflated, 

 thin, somewhat transparent, very closely ornamented 

 with fine raised strias, bifnrcated here and there ; 

 apertm-e large, wide, lip finely toothed, teeth rather 

 distant ; pale transparent flesh-coloiu'.

Hab. Cape of Good Hope. 



Lest this interesting little species may be taken for the 

 young of the Cyprcea oniscus, it may be observed that the 

 dorsal striae are much more numerous and regular, whilst 

 tlie denticulations of the outer lip are comparatively fewer 

 in number. There is, moreover, no dorsal impression, and 

 the striae terminate less abruptly on the columella. 



Species 109. (Mus. Cuming.) 



CYPRiEA costata. Ci/pr. testd globom-oblongd, tenui, in- 

 Jlntd, subpellucidd, latere dextro subincrassato ; striis 

 sublilibus nmnerosis elevatis, raro interrtqdis, widique 

 ornatd; aperturd ampld, laid; pallide rosed, apice 

 labroque alhicantibus. 



The eibbed Cowrey. Shell globosely oblong, thin, in- 

 flated, rather transparent, right side slightly thick- 

 ened ; ornamented tlu-onghout vi-ith numerous fine 

 raised stria;, rarely interrupted; apertm'e large, broad; 

 pale rose, lip and apex whitish.

Hab. ? 



I follow M. Deshayes in referring this species to the 

 Cyprcea costata of Gmelin ; but he has erred in stating that 

 M. Kiener has taken it for a variety of the Cyprcea oniscus. 



Species 110. (Fig. a and b Mus. Walton.

Cypr^a LUTEA. Cj/pr. testd subjiyriformi-ovatd, umbilicatd. 



laterihis marginatis, extremitatibus paululum reflexis ; 

 dorso lacteo-ccsruleo, puuctis luteo-fiiscis irregulariier 

 nebulatis, profuse iuquinato, lateribus extremitatibus 

 hanque luteis aurantiisve, nigricante-fusco punctatis, 

 dentibus pallidioribus. 

 The yellow Cowrey. Shell somewhat pyriformly ovate, 

 umbUicated, sides margined, extremities a little re- 

 flexed ; back nulky blue, profusely bedaubed with ir- 

 regidarly clouded yeUowish-brown dots, sides, extre- 

 mities, and base, yellow or orange, dotted with dark 

 brown, teeth paler.

 Hab. ? 



I quite agree with M. Deshayes in identifying this inter- 

 esting and rare species with the Cyprcea lutea of Grouovius; 

 the figure in the ' Zoophylacium ' is perhaps a little obscure 

 for want of colour, but the description, though short, is 

 sufficiently characteristic ; — " testa umbOicata, supra fus- 

 cesccnte albo-fasciata, subtus lutea punctis fuscis." 



This well-known state of the shell must, however, be 

 regarded as a variety, as we have it, in the collection of 

 Mr. Walton, as represented at Pig. 110 a and b, of larger 

 size and in a much more perfect and elaborately pauited 

 concKtion. The whole of the dorsal surface is a clear nulkv 

 blue profusely bedaubed with Ught brown splashes, cloud- 

 ing one with the other. 



An intennecUate state has been represented by Sowerby 

 in the Conchological Illustrations f. 55, copied so inaccu- 

 rately by Kiener as to exhibit a dot-banded character en- 

 tii'ely foreign to the species. 



Species 111. (Mus. Saul.) 



Cypr^a oniscus. Cypr. testd globoso-ovatd, valde inflatd, 

 latere dextro hicrassato ; striis elevatis aut vesictdis 

 bifiircatis et rugatis ornatd, impressione lavi dorsall 

 ceidrali; aperturd ampld, latissimd ; columelld Icevi ; 

 dorso rosaceo-carneo, basi albicaute.
