T. pyramidali, acuminata, spiraliter minutissime striata ; 

 anfractibus numerosis, rotundatis, sutura distincta; varicibus

A beautiful small white shell brought by Capt. Belcher 

 from New Guinea. It is finely striated in a spiral direction ; 

 most of the varices are thin, so as to be scarcely visible, with 

 here and there one more prominent.

T. pyramidali, acuminata, umbilicata, transversim striata ; 

 anfractibus rotundatis, numerosis, rapide crescentibus ; vari- 

 cibus plerumque tenuissimis, vel obsoletis, nonnullis crassis, 

 validis, arcuatis ; apertura ovali, auriformi, magna ; colore 

 albo. 



A well known species from the West Indies, frequently 

 confounded with, and possibly included in Sc. raricosta of 

 Lamarck, from which it totally differs. The greater part of 

 the varices are so thin as to be scarcely visible, but at irregu- 

 lar intervals thicker ones occur. There is a small specimen 

 from Isle Bohol in the Philippines, in which nearly all the va- 

 rices are elevated : it is found under stones, at low water, 

 by Mr. Cuming.

T. ventricosa, pyramidali, cancellata ; anfractibus rotun- 

 datis, rapide crescentibus ; sutura distincta ; varicibus raris 

 prominentibus, crenulatis, rotundatis, reflexis ; apertura

A ventricose shell, minutely cancellated, with here and 

 there a thick, crenulated reflected varix ; the aperture is 

 large, with a very small umbilicus behind it. Ceylon ?
