transparent, as in L. pellucida, but differs in being a little shorter, 
broader, with the spire lower, the apex less elevated, and the suture 
less impressed. The last whorl is more ventricose, and the outer lip 
and aperture are more broadly rounded. In alcohol, a specimen is 
1s™™ long; breadth, 12™™; height, 107”. 
Part of the differences in the soft parts may be due to variations in 
the amount of contraction. Both forms occur together, and some 
specimens are intermediate. - 
Off Martha’s Vineyard, stations 925, 937, 938, 939, 946, 1029, in 
224 to 458 fathoms. Several specimens of both sexes occurred. Off 
Chesapeake Bay.

A good living example of this shell was taken by us, on the 
“ Speedwell,” in 1877, off Halifax, Nova Scotia, in 57 fathoms (sta- 
tion 82).

Two living specimens were obtained, in 1881, which appear to 
belong to this species. They are more delicate and have somewhat 
finer and more regular radiating ribs than the ordinary European 
form. It had not been recorded before from our coast.

distinct species was taken in the Gulf of Maine, off Cape Sable, Nova 
Scotia, in 75 fathoms, by the United States Fish Commission party,
