Hab. Whydah. " Philippines " (Cuming). 



56. Ringicula suturalis, sp. nov. (Plate LXXV. fig. 12.) 



Testa ovata, alba, polita ; spira acuminata, sutura chorda callosa 

 cincta ; anfract. 5, convexi, spiraliter sulcati ; in anfract. ult. 

 sulci 10; apertura pyriformis ; columella callosa triplicata ; 

 labrum extra valide incrassatum.

 Hab. Whydah. 



This minute species belongs to the same striated group as R. pro- 

 pinquans, Hinds, from the Philippines and R. someri, De Folin, 

 from the Cape-Verd Islands. Its much smaller size, the number 

 and position of the teeth, and the callous chord around the suture 

 of the whorls well distinguish it.

58. Natica collaria, Lamk. Anim. s. Vert. ed. 2, vol. viii.

Hab. West Africa, Whydah.

Hab. Whydah. 



I hare compared the shells which I refer to this species with the 

 typical specimen in D'Orbigny's collection of Cuban shells in the 

 British Museum, and find that they are identical ; therefore this 

 species appears to be found in the Mediterranean (Malaga), Reeve 

 (Con. Icon. ix. sp. Ill), West Africa (Whydah), Knocker, and West 

 Indies (Cuba), D'Orbigny.

61. Natica rubro-maculata, sp. nov. (Plate LXXV. fig. 13.) 



Testa globosa, Icevis, umbilicata ; spira breviuscula ; anfract. 5, con- 

 vexi, infra suturam leviter depressi et oblique sulcati, lineis longi- 

 tudinalibus leviter undulatis et maculis subquadratis remotis au- 

 ra7itio-rubris (in anfr. ult. trifasciatim) ornati; columella recta. 

 Alt. maj. 15 mill., diam. maj. 15. 

 Hab. Whydah. 



A very distinct solid species, longitudinally lined, and with three 

 interrupted bands of squarish reddish spots encircling the last whorl ; 

 these bands are sometimes altogether absent, and sometimes there 

 are but one or two.
