Cypnva spJiaroides has a more sigmoid aperture and deeper apical pit 

 than C. pingiiis. 



Cyprcea pingiiis varies a Httle in relative height and considerably in size, 

 beside the variations due to age, in the appearance of the teeth, and the width 

 of the aperture. My largest Ballast Point specimen measures 34.0 mm. long, 

 and the smallest one only 19.0 mm. ! But such discrepancies are well known 

 among recent species.

This species is best described by comparison with C. pinguis. It differs 

 from the latter in being more cylindrical ; in its somewhat straighter and pro- 

 portionally narrower aperture, which is also less curved at the posterior com- 

 missure ; in being less elevated in proportion to its length, and having the 

 posterior slope of its dome less abrupt ; in being more attenuated laterally at 

 either end, and in the greater production of the extreme ends of the base ; 

 lastly, it appears to average smaller than pingiiis, and none of the specimens 

 indicate any such AriciaA\k.(t basal callus as pingiiis assumes in its fullest stage 

 of development. The specimens show nothing of the spire ; the teeth are 

 strong but small, and not extended (even faintly) across the basal callus; there 

 are twenty-two on the right lip and about eighteen on the left, which latter 

 are less prominent. The largest specimen measures 26.5 mm. long, 17.0 mm. 

 wide and 15.0 mm. high. The smallest was only 21.5 mm. long, but of about 

 the same proportions. 



This is a very pretty little species, and elegantly shaped. It seems suffi- 

 ciently distinct from C. pingiiis. It was collected at Ballast Point by Messrs. 

 Newman, Shepard and Crosby, where it was associated with the other fossils 

 of the silex-beds, and also in the orbitolite bed immediately above the silex- 

 beds, under and about the town of Tampa ; and it was found in the Eocene 

 (Vicksburg) limestone of Ocala, Florida, where it is represented only by 

 molds, by Mr. Willcox.

Shell large, solid, with a narrow, closely denticulate aperture, and slightly 

 flattened, moderately wide base ; the shell has much the form of C. cinerca, from 

 which it differs chiefly in its much larger size, more deeply cut and upturned 

 posterior commissure, and less swollen base. There are about twenty-two 

 teeth on the right lip, which appears to rise vertically inside the shell to a 

 rather unusual height, the whole of which is crossed by the teeth, which, how- 

 ever, do not extend laterally on the base. Max. Ion. of shell 46.0 ; lat. of 

 shell 32.0 ; alt. of shell 25.0 mm.
