374 PLIOCENE MOLLUSCA. 



the Wexford gravels, from which Mr. Bell reported it in 1890. We have lately 

 received a number of specimens of it from that locality, most of them small or 

 broken, as to the identification of which, however, taken as a whole, there can 

 be little doubt. Those here figured correspond with a small recent and slender 

 variety from Bergen (fig. 5) rather than with the large shell given on PI. XX, 

 fig. 1, as typical of this species. 



There are some broken specimens in the British Museum from Lewis in 

 the western Hebrides, labelled 8. propinquus. One of them, however, shows a 

 mammiform apex, and others the flattened spiral sculpture characteristic of 

 8. idandicus, to which species, I think, they should be referred.

Remarks. — The specimen here figured is one of two from the Jermyn Street 

 Museum which were found at Moel Tryfaen. They show the distinguishing 

 sculpture more clearly than those represented in PI. XX, figs. 10 — 12. Mr. Stewart 

 reports this species from the boulder-clay of Co. Antrim. 



8. latericeus appears to be a variable species; the recent Norwegian form given 

 by Prof. (x. O. Sars 1 is larger than those of PI. XX, and the spire is longer; it 

 seems to be very similar to the Neptunea (Sij)lio) pertenuis of Mr. E. R. Sykes. 2 

 We have others from Wexford which are intermediate. Possibly they are all 

 varieties of the same species.
