Fig. 638. A deep-water sliell. Very large 



specimens, much worn, are occa- 

 sionally found upon Chelsea and 

 Phillips's Beaches ; along the coast 

 of Maine, and farther eastward, they 

 are not infrequent. The small va- 

 riety is found abundantly in fishes 

 caught in our harbor, though I have 

 never found it washed ashore. Nova

1 formerly regarded the small 

 shells as the young, or a dwarf va- 

 riety of the type, though Mr. Sow- 

 erby is rather disposed to regard 

 them as a good species. And I had 

 also regarded the Fusus ventricosiis 

 as a variety abbreviatus of the same ; 

 but as I find it accurately described 

 by Dr. Gray, I have concluded to 

 follow him, since I can do it without

 Murex cornens of Linnaeus is said 

 to be the Fusus liijrnarius of La- 

 marck.

 ular specks of black ; eyes black ; foot rectangular, angles rounded.

Both Dr. Mighcls and Prescott having assured me that F. pjjg- 

 mcBus is distinct from F. Islandicus, and having sent me specimens 

 of the latter of equal length with those of the former, I find their 

 opinion quite correct. F. pj/in^mceus has at least two more whorls 

 than the young of F. Islandicus of equal length. The comparative
