TORELLIA VESTITA. 431 



Distribution. — lift-rut: Alaska, Behring Sea. 



Fossil : Pleistocene : Bridlington. 



Remarks. — In 1848 Wood figured a fossil from Bridlington as T. boreal is, 

 var. incrassata (op, cit.) which afterwards, in the 2nd part of his 1st 

 Supplement (1874), he referred to a recent Behring Sea species, T. insignis, 

 Middendorff. There are three specimens in the Sedgwick Museum at Cambridge, 

 evidently the same as Wood's shell, which, though not agreeing altogether 

 with Middendorff's figures, belong to the same group, approaching to his 

 T. insignis more nearly than to the British T. borealis. I figure one of the 

 Bridlington fossils under the name adopted by Wood, but as a variety, and 

 with it a typical example of the recent Behring Sea species from Alaska which 

 Dr. Dall has kindly sent me. The latter is larger than those from Bridlington, 

 and the mouth is wider and much more expanded. Our Bridlington fossils have 

 a general resemblance to Dr. Dall's species and may be regarded, perhaps, as a 

 slender variety of it. They seem to me more nearly related to the latter than to 

 T. borealis. Grouping it with T. insignis, I adopt for the present shell the varietal 

 name of Woodii.
