﻿218 DEVONIAN FAUNA. 



Collection of the Torquay Museum probably from Wolborough ; and two less 

 perfect examples in my Collection, another small doubtful specimen in the Wood- 

 wardian Museum, and another in the British Museum, from Lummaton. 



Remarks. — This species seems to stand about midway between G. tylotus, 

 n. sp. and G. invictus, n. sp. From the former it is distinguished by its more 

 regular spiral shape, less expanded mouth, and the absence of tubercles ; and from 

 the latter by its sunk and less perfect spire, and the absence of a defined spiral 

 sulcus on the lower part of the whorl. 



Affinities. — Capulus substriatus, Minister, 1 seems to approach this form. It 

 appears to have a more perfect spire, to be more circular in section, and to be 

 ornamented with spiral striae, thus forming in some points a passage between the 

 present species, G. invictus, n. sp. and C. compressus, Goldf. 



Capulus neritoides, de Koninck, 2 from the Carboniferous, seems to have a small, 

 but more developed spire than any of these species. It consists of more than two 

 volutions. 



Naticopsis obliqua, Trenkuer, 3 as given by Clarke,* is a higher shell with a mouth 

 more pronounced and angulated above, and a not-sinuous, round, thickened inner 

 lip. It is, however, generally similar, and indicates that the present species is 

 closely allied. In Trenkner's own figure the spire is larger, and there are 

 regular distant longitudinal ridges. It is evidently not accurately drawn, but it 

 shows, I think, that it clearly is a different species.
