Prof. E, Forbes on Fossil Invertebrata from Southern India. 127 



A very imperfect specimen of a very well-marked species. The diagnostic cha- 

 racter embodies all its features, so far as shown in the .example described. Its 

 nearest allies seem to be the shells named by D'Orbigny Fusus Hieranus and Fusus 

 neocomiensis , both French cretaceous forms. 



Locality, Pondicherry. 



2. Murex pondicherriensis, sp. nov. PI. XIIT. fig. 20. 



M. testa inflate, anfractibus convexis, tumidis, ad suturas planiusculis, longitudinaliter spi- 

 raliterque decussato-costatis ; apertura lata, ovata, canali brevi. 



Length 1 inch. Breadth of last whorl Of inch. Length of aperture nearly Of inch. 



A ventricose, short-spired shell, with a very large and tumid body-whorl which 

 is crossed by fifteen longitudinal ribs, decussated and rendered strongly nodulose 

 by equidistant spiral ribs. This is also the case in the upper whorls. The mouth 

 is ovate and the canal short and broad. 



Locality, Pondicherry. 



3. Murex trinchinopolitensis, sp. nov. Pi. XV. fig. 7. 



M. testi oblong^, turriti, crass^, anfractibus 6, longitudinaliter costatis, transverse costato- 

 striatis, costis longitudinalibus crassis, prominentibus, variciforraibus, superne subangulatis ; 

 apertura oblonga, labro externo incrassato. 



Length 1^''^ inch. Breadth 0/^ inch. 



Shell oblong, thick, whorls six, those of the spire, which is rather more than 

 half the length of the body-whorl, gradually decreasing and angulated : all, as well 

 as the body-whorl, crossed by strong ribs, which are angulated at some distance 

 from the suture : these ribs resemble varices, are rounded and nearly equal. There 

 are eleven of them on the body-whorl, that at the back of the mouth being strongest 

 and most variciforra. They are crossed by regular equidistant spiral cords, which 

 are obsolete above the angle of each whorl. Between each pair of spiral cords are 

 three or four deep spiral striae ; their interstices are minutely fenestrated by lines 

 of growth, which also cross over the spiral threads. The mouth is obscured by 

 stone. The canal was short. The shell has much the aspect of a Triton. 



Locality, Trinchinopoly ; a single specimen in fine preservation. 



Genus Pyrula, Lamarck. 



1. Pyrula pondicherriensis , sp. nov. PI. XII. fig. 19. 



P. testa oblongo-pyriformi, spira brevissima, convexiuscula, anfractibus 3, costis longitudi- 

 nalibus spiralibusque regulariter fenestratis : apertura (oblonga) labro externo margine den- 

 tate. 



Length of largest specimen 3 inches. Breadth li inch.
