46 DEVONIAN FAUNA. 



Size. — Height 2 mm., width 1'5 mm. 



Localities. — Baggy {vide Phillips). One or two small casts from Ironpost, 

 near Dulverton, in my collection, appear to belong to this species. 



BemarJcs. — I have not met with any undoubted specimens of this shell, but the 

 above-mentioned casts probably belong to it. They are globose shells with half- 

 exposed, quickly-increasing whorls, which (in the cast) are convex on the shoulder 

 and nearly fiat on the broad back. They agree with Phillips's figure in dimensions, 

 except that perhaps they are slightly wider. 



Affinities. — From Naticopsis HallH they differ in being much smaller, less 

 oblique, and more elongate and turrited. 



III. Family. — Capdlid/e, Fleming, 1828. 

 1. Genus. — C apulus, Jlfo?i^/or^, 1810.

figs. 6—8. 



Locality. — One or perhaps two small specimens are in the Porter Collection 

 from Pilton. 



Bemarhs. — Mr. Porter's specimen undoubtedly agrees, I think, with 

 Wolborough and Lummaton fossils referred by me to this somewhat doubtful 

 species. The body-whorl is deeply concave below and very much flattened. 

 The apex would seem to be much closer to the plane of the mouth than it is 

 in the South Devon specimens. 



A very similar specimen was found by Dr. Hicks and myself at Freshwater 

 West, Pembrokeshire.
