Tliere is a pecidiarity in the coloming of this species 

 which, carefidly observed, serves amply to distinguish it 

 fi-om the C. Eitropo'a, with which it is neaily aUied. 



Species 1.50. (Mus. Saul.) 



Cype^a pulla. Cypr. testd rotmido-ovatd, subventricosd, 

 extremitatibiis subobtmis ; fransversim subtiliter costatd,

The brown-coloured Cowrev. SheU ovate, sUghtly

Eab. ? 



"\ery Uke the C. svhrostrata, but upon examination it 

 wiU be found to be rather more oblong in form, and with- 

 out any distinct dorsal groove ; the colom- is also of a 

 more transparent character. 



Spectes 151. (Pig. 151 and 154, Mus. Gaskoin.) 



Cypr.ea candidhla. Cypr. testd globoso-matd, laterilms 

 siibddatatis, margine incrassatis ; transversim midique 

 costatd, costis fort'dtus, subconspicmis ; nived. 



The little white Cowrey. SheU globosely ovate, 

 sides somewhat dilated, thickened at the edge ; trans- 

 versely ribbed throughout, ribs strong, rather con- 

 spicuous ; snowy white. 



Gaskoin, Pro. Zool. Soc., 1835. 



Hab. Jlexico. 



This interesting little species may be distinguished by 

 the forcible character of the ribs ; as a proof of its specific 

 importance Mr. Gaskoin relates the circumstance of it 

 having been abnost simultaneously described in two other 

 cities of Europe, in Paris by M. Ducios under the name 

 of C. olorina, and in Copenhagen by Dr. Beck under that 

 of C. approxinmns.
