APPENDIX. 357 



It is of a perfectly fusiform shape, and the upper parts 

 of the whirls next to the suture are flattened and hol- 

 lowed out into broad channels. The surface is encircled 

 with numerous, close-set, raised striae, which are of 

 unequal size, every fourth one being larger than any of 

 the intermediate ones, and all roughened by numerous 

 small scales. The whirls are six or seven in number 

 (the upper ones being unfortunately broken otf), and 

 rapidly increase in size, the last being two-thirds the 

 length of the whole shell. The columella is covered 

 with a turned-over plate of the inner lip, the umbilicus 

 being partially concealed by it. The lower canal is of 

 considerable length, and is bent to one side. The 

 mouth appears to be rather small in proportion to the 

 size of the shell. When taken, it was inhabited by a 

 species of Pagurus, and, as is customary with shells 

 similarly inhabited, was considerably injured by its 

 parasitic tenant. Long. 3 inches; lat. 1^ inch. Hob.
