NATICA. 343 



R. Howse. A dead specimen was dredged in forty-five 

 ftithoms ofF Rasa (M'Andrew and E. F.) but this may 

 possibly have been a pleistocene fossil. It occm'S fossil in 

 the Bridlington beds. It now ranges northwards to the 

 seas of Greenland. •

Our description of this strange looking Natica (?) is 

 solely derived from an unique example now in the collec- 

 tion of Gwyn Jeffreys, Esq. Its dorsal aspect reminds 

 one of Lacuna pallidula^ its ventral of an Anculotus. It 

 is ovate-acute, oblique, strong enough for its size, not 

 translucent, and clothed with an olivaceous yellow lustrous 

 epidermis, that fits it so tightly as to seem rather an 

 external layer of colouring matter. Beyond mere wrinkles 

 of increase, that are frequent and rather conspicuous, no 

 sculpture either external or internal varies the entire sur- 

 face. The prominent spire, which is not placed laterally 

 as in the Lacuna pallidula, terminates in a small and not 

 peculiarly blunt apex, occupies nearly a third of the dorsal 

 length, and is composed of rather more than three much 

 tapering rounded volutions, that are short, of very quick 

 longitudinal increase (the penult being large in propor- 

 tion to the earlier turns), and clearly defined by a simple 

 sutural line. The peculiarly broad body is ventricose, yet 

 becomes slightly flattened towards the outer lip ; it declines 

 anteriorly in a rather abrupt convex line, and terminates
