﻿NEW CRETACEOUS FOSSILS. 331 



nent, angular, acute, short on the back of the body volution, but extending in front 

 to a carinated line which borders the labrum ; transverse striae distinct at base ; labrum 

 extended into the rostrum above the middle, where it is angulated and subcarinated 

 and channelled within. 



, The beak is broken as well as the rostrum of the outer lip, but otherwise the only 

 specimen in the collection is very well preserved. 



HARPAGO, Klein.— PTEROCERA, Lam.. 



Haepago tippanus. PI. 35, fig. 25. A fragment, with smooth subangulated volu- 

 tions, a carinated line revolving at the base of each ; rostrum of the labrum pro- 

 foundly extended, trilobate, the central and upper lobe profoundly carinated in the 

 middle ; substance of the shell thin. 



The labrum has evidently been extended above the apex, but only a slight trace 

 of it remains near the upper part of the spire. The specimen is evidently a young 

 or immature shell. 



RIMELLA? Agass. 



Rimella curviliratus. PI. 35, fig. 9. Fusiform, ribbed longitudinally; ribs 

 somewhat curved, slightly sinuous, about twenty-three in number on the body volu- 

 tion ; interstices transversely striated ; beak produced ? 



CONUS, Lm. 



Conus canalis. PI. 35, fig- 22. Spire prominent, volutions profoundly angular 

 in consequence of a deep channel revolving at the suture. 



A very remarkable species, in its profoundly channelled suture presenting a strong 

 contrast to more modern fossil or recent cones. 



DRILLIA, Gray. 



1. Drillia novemcostata. PL 35, fig. 13. Subfusiform, spire elevated; volutions 

 scalariform, having distant, wide, prominent, rounded slightly oblique costse, termi- 

 nating above at a crenulated line which borders the suture ; body volution with short, 

 very prominent, tuberculiform, thick ribs ; revolving lines obsolete above, prominent 

 and alternated inferiorly. 



2. Drillia ? tippana. PL 35, fig. 5. Subfusiform, with thick, rounded, smooth, 

 longitudinal ribs on the body volution, each tuberculiform at the summit ; ribs of the 

 spire tuberculiform at base, or interrupted in the middle ; base with thick, prominent 

 revolving lines.
