Hah. Off Andaman Islands, in 490 fath. 



The tubercles are somewhat 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 

 same group as IS. lissocona^ Dall, and a few other species. 

 One specimen only. 



29. Fissurella delicata. 



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

 iufequalibus numerosis lirisque concentricis confertis supra cosfcas 

 nodulosis teuuiter cancellata ; foramen apicale rotunde ovatum,

 teuuiter crenulata. 



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



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



Allied to F. densiclathrahx , Reeve, but more elevated, more 

 delicately clathrate, with the apical foramen more central. 

 Also thinner and without colour-rays.

 termiualis, sed margine louge remotus ; margo basalis crenulatus, 

 ad latera leviter arcuatim elatus ; foramen elongatum, angustum, 

 medianum. 



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



Ilah. 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. Tellina travancorica. 



Testa inoe(i[uilateralis, compressa, alba, lamellis coucentricis tenuis- 

 simis confertis ornata, elongata, autice rotuudata, postice sub-
