CYPR2EA. 41 



140. Madagascariensis, Gmel. (f. 406-408). — C. testa 

 nuclei simili sed ruajori, inagis depressa ; lateribus expansis ; 

 basi inagis coniplanata, costellis distantibus elevatis ; termi- 

 nis obtusis. 



Note. — Nucleus and Madagascariensis. The more flat- 

 tened form and expanded sides of the latter, with the more 

 distant basal riblets, are sufficient to distinguish it from the 

 former. 



141. Childreni, Gray (f. 403-405). — C. testa ovata, sub- 

 cylindrica, fulva, ad extremitates laminis exstantibus mar- 

 giuata ; extremitatibus angustatis, productis, posticis trun- 

 catis ; costellis transversis, ad lineam dorsalem plurimis 

 coutinuis, alteris duplicatis ; apertura angustissima. 



Note. — The dorsal ribs do not radiate at each end as in 

 Trivice, nor are they quite spiral as in Adamsoni. The ter- 

 minations of this shell are very peculiar, having wing-like 

 lateral projections. In form, radiation of teeth, etc., it is 

 nearly allied to the following species. 



142. cicercula, Linn. (f. 343, 344, 345, 346).— C. testa, 

 globosa; dorso elevato, plus minusve granuloso, fusco-au- 

 rantio vel pallide luteo, minute punctato, interdum maculis 

 magnis ornato ; linea dorsali subconspicua ; extremitatibus 

 productis, callosis, acurninatis ; basi subconvexa ; maculis 

 quatuor castaneis plerumque picta; dentibus linearibus, 

 elongatis ; apertura angustissima. 



143. globulus, Linn. (f. 347, 348). — C. testa G. cicerculce 

 affini, magis oblongo-cylindrica ; dorso lajvigato ; linea, dor- 

 sali obsoleta ; basi immaculata. 



Note. —Gicercu.la, globulus. Cicercula is sometimes granu- 

 lated, and has four basal spots. It is more rounded than 

 globulus, which is never granulated and has no basal spots. 



144. chrysalis, Kien., (f. 335, 336). — C. testa C. cicerculce 

 forsan affini, sed angustissima, pallida. 



Note. — I do not know this shell, the figure of which I 

 have copied, and only suppose it may be allied to cicercula or 

 globulus, unless it has been described from a very young 

 specimen of some well-known species. 



145. annulata, Gray, (f. 339, 340). — C. testa ovato-globosa, 

 obtuse subrostrata, pallide fulva, ; dorso lateribusque maculis 

 rotundis luteis annulatim circumscriptis inasqualibus pictis ; 

 apertura angustissima, subtortua; dentibus minutissimis.
