392 PLIOCENE MOLLUSC A. 



In a list of recent shells from the eastern coast of North America, recently 

 published by the Boston Society of Natural History, Mr. C. AY. Johnson gives the 

 undermentioned localities for certain species of Bela in addition to those already 

 recorded in this Memoir, viz. B. exarata as B. concinnata Verrill, and B. rosea* 

 G. 0. Sars, as well as Buccinvm perdix, Beck, from Maine and Massachusetts, and 

 the freshwater Bithynia tentaculata from Lake Champlain. 1

 fig. 11, 1910 ; B. cancellata (Mighels), K. Svensk. Vet.-Akad. Handl, vol. liv, p. 213, 1915. 



Specific Character*. — Shell slender, elongato-fusif orm ; whorls 7, convex, sharply 

 angulated, with a sloping shelf below the suture ; spire turreted, with a rather blunt 

 apex; ornamented by strong, prominent and flexuous costas, nodulous on the keel, 

 crossing the shelf obliquely and reaching the suture, also by numerous fine 

 spiral ridges; suture deep; mouth considerably less than half the total length, 

 slightly angulated by the keel. 



Dimensions. — L. 14 mm. B. 4 mm. 



Distribution. — Recent: Finmark, Iceland, Spitsbergen, Greenland, Labrador. 

 Fossil : Bridlington. Iceland Crag. 



Remarks. — The Bridlington fossil here figured is from the Leckenby collection 

 at the Sedgwick Museum. It agrees very closely with the description given by 

 Prof. Sars, and especially with the figure published by Dr. Odhner (op. cit.). In 

 a letter recently received from the latter, however, he expresses the opinion that 

 his shell may be a variety of B. cancellata, Mighels (non Sars). Comparing the 

 figures of B. cancellata and B. angulosa, published by Prof. G. 0. Sars, our shell 

 corresponds most closely with that of his B. angulosa.

Distribution. — Fossil: Wexford gravels (additional). 



Be marls. — Among some Belas received from Wexford since the publication- 

 of p. 298, there is one which seems to correspond more nearly with the 

 specimen of B. borealis from the Iceland Crag than that there figured (op. cit.
