in the Bay of Biscay and on the coasts of America. Cancella- 

 ria Smithii (Fig. 292), an elegant new species 

 of a comparatively rare group ; Mitra Swainsoni 

 (Fig. 293) of Broderip, from the deep water of the 

 West Indies, first described from Chilian waters ; 

 and Typhis longicornis (Fig. 294), a pretty flesh- 

 colored deep-water species, — may be cited as ex- 

 amples of other groups, the last being particu- 

 larly remarkable from the length of its spines, 

 which could only exist in the shell of an animal 

 surrounded by a soft bottom and living in per- 

 fectly calm water.
