 are somewhat smaller than those farther out stand nearly in one row, 

 with wide spaces between them. Diameter of largest suckers, 9 to ll mm ; 

 distance between their centers, 20 to 35 mm . Color, dark purple.

Shells of this species, some of them entire, were taken by the " Fish 

 Hawk" at several of the stations 70 to 115 miles south of Martha's Vine- 

 yard and Newport, E. I., in 64 to 365 fathoms. At least nine specimens 

 were dredged. At station 894, in 365 fathoms, two entire and nearly 

 fresh shells were taken, and another nearly complete. They belong to 

 the common Mediterranean variety. Fragments were also taken at sta- 

 tions 865-7, 871, 873, 876, 892, 895. 



The capture of a living specimen, probably of this species, on the 

 coast of New Jersey, has been recorded by Rev. Samuel Lockwood, 

 in Amer. Naturalist, xi, p. 243, 1877.
