NEPTUNE A DESPECTA. :W.) 



form of the Wexford N. antiqua or a survivor of the Orag X. coiitraria, I express 

 no opinion. It does not appear to be the variety Informix described in the last 

 paragraph but closely resembles the dextral specimen figured with it.

Varietal Characters. — Shell short, fusiform, turreted; whorls convex, flattened 

 above with a sloping shelf below the suture, the last much the largest, three-fourths 

 the total length, excavated below; ornamented by spiral ridges, two of them 

 prominently shown on the upper whorls, more numerous on the last, the lower ones 

 being less clearly marked ; spire conical, regularly diminishing in size upwards ; 

 suture fairly deep ; mouth oval, equalling the spire, angulated above ; outer lip 

 curved, slightly angulated by one of the spiral ridges ; canal short, bending to 

 the left. 



Dimensions. — L. (of Wexford specimen) 45 mm. B. 24 mm. 



Distribution. — Recent : Arctic Norway, Kara Sea, Spitzbergen, Nova Zembla, 

 Iceland, Newfoundland, Labrador, Greenland. 

 Fossil : Wexford. 



Pleistocene : Sweden, Siberia, Montreal, Quebec, Riviere-du-Loup, Labrador. 



Remarlcs. — The specimen from Wexford figured under this name belongs to the 

 carinated and northern despecta group. It agrees closely, both in form and 

 sculpture, with that figured by Prof. Leche as Fusus tornatus, and to a somewhat 

 less extent with Gould's typical American shell {op. cit.), though it is rather more 

 slender than the latter. The range of this group, both as recent and fossil, is 

 distinctly arctic and northern, extending westward also to the northern part of the 

 American continent. 



It may be pointed out that the sinistral Neptuneas found at Wexford outnumber 

 the dextral ones by about ten to one.

Specific Gluiracters. — Shell rather thin, ovato-f usiform ; whorls 6, convex, the 

 last much the largest, four-fifths the total length, rounded but not so tumid as in
