CVCLOSTREMA SOLARIELLUM, Sp. IIOV. (PI. I, f. 20). 

 C. testa ininntA, albescente, teniii, depressd^ profundi 

 umbilicatd, anf-actibus quatiior, ultimo rapide accrescente, 

 undiqiie transversim teniii-liratis, infra siituras binis

 Not uncommon in shell sand.

Hab. Bombay {Abercrombic). 



A small subconical plain smoothish brown species, 

 with biradiate flames round the margin. I had thought 

 this, of which very numerous examples occur in Mr. Aber- 

 crombie's collections, must be a young form of some perhaps 

 well-known species, but I am assured this is not the case, 

 Mr. Abercrombic having had unusual facilities for studying
