cle. The pedicle is very short, of a cylindrical shape, 

 and covered with short hairs. 



The L. Scalpellum inhabits the North seas ; Linnaeus 

 observed it on the coast of Sweden, Muller on that of 

 Denmark, and it also occurs, though rarely, in the British 

 ocean. It is never found thrown on the shore like other 

 shells, but is taken in the deep, and always attached to 

 some other body. The specimen figured in pi. 10 

 adheres to the lobster horn coralline, Sertularia antennina. 

 It is not uncommonly attached to different species of 

 the genus Gorgonia, and sometimes to Fuci. The 

 valves are often encased in extraneous matter, so that 

 the divisions are not visible. In this state it is repre- 

 sented by D'Argenville, and also by Ellis at fig. 3. 



Gmelin's reference to Lister and Klein for this shell 

 is wrong. Lister has figured the L. Pollicipes, and 

 Klein, of course, has copied him.

The principal valves of this shell are concentrically 

 wrinkled from the exterior angle to the base, and faintly 

 radiated with striae from the same point across the 

 wrinkles. The dorsal, or ridge valve, is singularly 

 dilated at the base, and has a sharp prominent angle, or
