Species 97. (Mus. Cuming.) 



Cypr^a ziczAG. Cypr- testa subpyriformi-ovatd, umbili- 

 catd, dentihus ml/eloni/atis ; dorso alMcmiie, lineis 

 jlavescentilus undatm loncjitudinaliter ornato, lateribm 

 basique rufo-aurantiis nigro vwidepundatis. 



The ZIGZAG Cowrey. SlieU somewliat pyriformly ovate, 

 umbilicated, teeth rather elongated ; back whitish, 

 ornamented with longitudinal zigzag yellow lines, sides 

 and base reddish orange brightly dotted with black. 



LiNNEUS, Syst. Nat. (12th edit.) p. 1177. 



Hab. Mozambique (under stones) ; Hennah. 



There is a beautiful variety of this ancient, though not 

 abundant, species, iu which the zigzag lines resolve them- 

 selves into distinct bands. The base is very similar to 

 that of the Cyprcea lutea. 



Species 98. (Mus. Cuming.) 



Cype^a asellus. Cypr. testa oblongo-ovatd, lateribus vix 

 marginatis, dentibm sulelongatis ; ebiirned, dorsofasciis 

 tribus latis nigro-fusch ornato. 



The little ass Cowrey. Shell oblong-ovate, sides very 

 slightly margined, teeth a little elongated ; ivory white, 

 back ornamented with three broad blackish-brown 

 bands. 



LiNNEUS, Syst. Nat. (12th edit.) p. 1178. 

 B.ab. West Indies. 



It is curious to observe that the very characteristic dark 

 bands of this species are not deposited at the last ; they 

 appear in all the earlier stages of growth winding roimd 

 the columella, and in the adult are cut off, as it were, on 

 each side by the supei-position of a layer of ivory white. 



Species 99. (Mus. Cuming.) 



CypkzEA poraria. Cypr. testa subabbreviato-ovatd, cras- 

 siuscidd, lateribus subindist'mctefoveolatis, deutibus sub- 

 elongatis ; extremitatibns obtusis ; fidvd, dorso punctis 

 albia nmnerosis, quibttsdam fusco-anmtlatis, ornato, late- 

 ribus basique purpureo-violaceis. 



The porous Cowry. Shell shortly ovate, thick, sides 

 rather indistinctly pitted, teeth a little elongated, ex- 

 tremities obtuse ; fulvous, back ornamented with 

 numerous wlute dots some of which are encircled 

 with brown rings, sides and base pm-ple-violet. 



Linneus, Syst. Nat. (12th edit.) p. 1180. 



Hab. Taheite, Pacific Ocean (on the reefs) ; Cuming. 



The painting of this species is very similar to that of the 

 Cypraa albtiginosa, but it may always be distinguished by 

 its more diminutive and stunted form.
