Breadth of body- whorl with its claw 2j^^ inches. Narrowest part of claw 0^^ inch. Across 

 the hooks about 1^^ inch, 



A fragment of a large and very distinct species, having a much-produced 

 halbert-shaped outer lip, which is carinated at the back. The surface appears to 

 have been quite smooth. It approaches some gault forms. 



Locality, Pondicherry. 



3. Rostellaria palliata, sp. nov, PL XIII. fig. 15. 



R. testa elongate, laevissima, polita, spira producta, attenuate, labro externo in spiram pro- 

 ducto et apicem incrustante. 



Largest specimen 2 inches long. Spire 1 inch. Breadth Oy^^ inch. 



A beautiful and very remarkable species, having a spire nearly equal to the 

 body-whorl in length, but, though bare in the young specimen, becoming when 

 full-grown enveloped in the callus-like continuation of the outer lip, which enve- 

 lopes it so that only the body-whorl and part of the second, third, and fourth 

 volutions are exposed, the apex being entirely covered. The surface is beautifully 

 smooth and polished. 



Locality, Pondicherry. 



Genus Strombus, Linnseus. 



1. Stromhus uncatus, sp. nov. PI. XIII. fig. 16. 



S. testa late ovata, crassa, anfractibus 6, convexiusculis ; spir^ exserta, laevi : ultimo anfractu 

 superne regulariter flexuoso-sulcato ; labro externo dilatato, late aliformi, postice incrassato, 

 margine crassissimo, superne sinuato, emarginato, inferne cauda hamate ; labro interno cras- 

 siusculo, spiram vix incrustante. 



Length l^^ inch. Breadth l~ inch. Length of body-whorl Ij^ inch. 



Somewhat triangular in form in consequence of the peculiar shape of the wing- 

 like outer lip, which is notched above and gradually curves to the canal, which 

 suddenly turns forward in the form of a hook. The back of the lip is strongly 

 thickened. The body-whorl is marked for its upper two-thirds with flexuous 

 regular sulcations, ten to twelve in number. The spire is smooth and short, but 

 prominent. The superior cleft claw of the lip does not rise as high as the suture 

 of the body-whorl. The young shell is smooth and resembles a Buccinum. The 

 cast is smooth and polished. It is distantly allied to the French Neocomian 

 Rostellaria alpinus. To the next species it is intimately related. They are both 

 abnormal forms of the genus Strombus. 



Locality, Pondicherry, where it appears to be common. 



2. Strombus contortus, G. B. Sowerby, MSS. PI. XV. fig. 9. 



S. test^ oblonga, crassa, spiri exserta, anfractibus 6, superioribus costatis, ultimo semicos-
