﻿CAPULUS. 215 



Remarks. — There is considerable variation in the three specimens placed under 

 this heading, but on the whole they present such a general similarity as to lead to 

 the conclusion that they belong to the same form ; and they appear to be widely 

 different from any of the accompanying fossils. Thus my smaller specimen is a 

 narrower shell with a more tapering apex, and with the growth-lines strongly 

 flounced all over by spiral constrictions. In Mr. Vicary's specimen (PL XXI, 

 fig. 4) these marks are only seen near the base of the whorl, while in the 

 other specimen, which in every other respect agrees with that last named, there 

 are hardly any indications of them at all. In every case the true shape of the 

 beak is obscured by the partial absence of the outer shell. 



On the whole, the species may be defined by its subglobose form, its great 

 height, and its minute recurved apex. 



Affinities. — Of the adjacent species, it appears to approach most nearly to 

 Gapulus Ussheri, n. sp., and Capulus terminalis, n. sp.

pi. v, fig. 13. 



Description. — Shell large, depressed, obliquely conical. Spire apparently unde- 

 veloped. Apex turned upward, much overhanging the inner margin of the mouth. 

 Body- whorl almost circular in section except on the inner side ; gently convex in 

 horizontal contour, regularly and rather slowly increasing. Mouth apparently 

 very large and oblique, with a thickened fold upon its upper edge. Surface of 

 the under shell showing indistinct growth-lines, and very fine, sharp, transverse 

 markings, five or six times as numerous as the growth-lines, which meet and sepa- 

 rate, so as to form a compressed network. Surface of the upper shell showing 

 similar markings, but somewhat coarser. 



Size. — Width about 40 mm., depth about 27 mm., height 20 mm. 



Locality. — From Lummaton there is one specimen in my Collection, and from 

 Wolborough one specimen in the Museum of Practical Geology. 



Remarks. — The specimen figured on PI. XXI, fig. 6, is unfortunately very 

 defective. The lower part of the shell is gone, so that the line of the mouth, and 

 therefore the elevation of the apex above the mouth, cannot be made out. It was 

 therefore impossible to decide the true position in which the figure should be 

 drawn, and possibly it is represented as more upright than it ought to be. The 

 other specimen differs considerably in shape, being flatter and more circular.
