Description of some New Species of Fossil Shells. 99 



Genus Cancellaria. — Lamarck. 

 C. pulcherriina. PI. 1, fig. 15. 



C. testa sub-fusiformi, cancellata, striis longitudinalibus gequali- 

 bus transversis, lineis crebrissimis parvis, transversis, sub-crassa, 

 umbilicata ; spira obtusa, mammillata ; anfractibus senis, con- 

 vexis, SLiperne angulatis ; suturis inipressis ; umbilico parvo ; col- 

 umella duabis plicis ; apertura sub-elliptica ; canale brevissimo ; 

 labro crassissimo. 



Shell sub-fusiform, cancellate, with the longitudinal strisB 

 equal to the transverse ones, with small transverse lines very near 

 each other, somewhat thick, umbilicate ; spire obtuse, mammil- 

 late ; whorls six, convex, angular above ; sutures impressed ; um- 

 bilicus small; columella with two folds; mouth sub-elliptical; 

 canal very short ; outer lip very thick. 



Length -4. Breadth of an inch. 



Remarks. — This elegant little species is remarkable for the 

 raised points at the intersections of the longitudinal and trans- 

 verse striae, which render it muricated, and give it a beautiful ap- 

 pearance. It resembles considerably C. multiplicata^ Lea, but 

 may easily be distinguished from that species, by its being cancel- 

 late and muricate, but I cannot determine whether the shape of 

 the mouth diflfers, as the outer lip of uiy only specimen is very 

 much fractured. The mouth is just half as long as the shell. 



Genus Triton. — Lamarck. 

 T. pyramidatum. PI. 1, fig. 16. 



T. testa turrita, crassa, polita, transverse striata ; spira acuta ; 

 anfractibus nonis, convexis ; suturis impressis ; columella Igevi ; 

 apertura sub-elliptica, sub-effusa. 



Shell turrited, thick, polished, transversely striate ; spire acute ; 

 whorls nine, convex ; sutures impressed ; columella smooth ; 

 mouth sub-elliptical, somewhat effuse. 



Length . Breadth -3 of an inch. 



Remarks. — It is with some hesitation that I have placed this 

 shell in the genus Triton, to which, however, it appears to be- 

 long, from its irregular varices, of which some of the whorls have 

 but one, and some two. It appears to have had a rostrum at the 

 base of the mouth, but as I have only a single specimen, which 

 has it broken, I cannot determine its size. It is remarkable as
