The tubercles are somewliat scale-like or hollowed out on 

 the anterior side, the third lira from the umbilicus exhibiting 

 only a few anteriorly near the aperture. Belonging to the

 One specimen only. 



29. Fissurella delicata. 



Testa ovata, conica, elata, tenuiuscula, sordide albida, costis tenuibus 

 iniequalibus numerosis lirisque concentricis confertis supra costas 

 nodulosis tenuiter cancellata ; foramen apicale rotunde ovatum, 

 paulo ante medium situra ; pagina interna albida, ad marginem 

 tenuiter crenulata. 



Longit. 28 millim., diam. 18 ; alt. 13. 



Hah. Station 232, off Travancore coast, 430 fath. 



Allied to F. densiclathrata^ Reeve, but moi'e elevated, more 

 delicately clathrate, with the apical foramen more central. 

 Also thinner and without colour-rays.

Testa pileiformis, ovata, alba, teuuis, costeUis numerosis tenuibus 

 insequalibus, alternatim majoribus, lirisque concentricis supra

 terminalis, sed margine longe remotus ; margo basalis creuulatus, 

 ad latera leviter arcuatim elatus ; foramen elongatum, angustum, 

 medianum. 

 Longit. 6 millim., diam. 4"5 ; alt. 4. 



Hah. Station 232, off Travancore coast, 430 fath. 

 Scarcely separable from the Japanese P. pelex. It is, 

 perhaps, a trifle broader, less produced above, has the apex 

 curved over more terminally, the margin slightly arched at 

 the sides, and the dorsal opening narrower. 



31. TelUna travancorica. 



Testa inaequilateralis, compressa, alba, lamellis concentricis t^nuis- 

 simis confertis ornata, elongata, antice rotundata, postice sub-
