A. E. Verrill—Mollusca of the New England Coast. 251 
Taranis Morchii, var. tornatus Verrill, nov. 
Two specimens from station 2077, in 1255 fathoms, are somewhat 
stouter than those previously obtained, and have the principal carina, 
forming the shoulder, larger and more prominent than usual, but it 
bears only very minute tubercles, corresponding to the very fine and 
close riblets which cross the wide and abruptly sloping subsutural 
band obliquely, and are about twice as numerous and much finer 
than in the ordinary variety. On the last whorl there are about six 
prominent, distant, revolving cinguli below the shoulder, besides 
some faint ones on the base of the canal; the space between the 
uppermost of these and the shoulder-carina is greater than usual. 
The lines of growth are much finer than in the ordinary form and 
do not take the appearance of riblets on the last whorl, nor do they 
render the cinguli nodulous. The suture is sharply impressed, and 
the raised revolving line usually present just below the suture is 
absent. This form, therefore, is characterized by the relative pre- 
dominance of the spiral sculpture over the transverse, and by the 
absence of distinct nodules at the crossing of the two systems of 
lines.

Bush, Proc. U. 8. Nat. Mus., vol. vi, p. 238, pl. 9, fig. 12, 1883. 
Miss Bush has recorded this species from Labrador, at Henley 
Harbor and Dead Island, in 1 to 8 fathoms. 
The figure referred to represents the same form as that which was 
described by me from the Gulf of St. Lawrence, and which has been 
referred by Whiteaves and others to S. Spitzbergensis. 
Tritonofusus cretaceus (Reeve.)

Tritonofusus cretaceus Bush, Proc. U. S. Nat. Mus., vol. vi, p. 238, 1883. 
Miss Bush has recorded this species from Labrador, in 3 to 10 
fathoms. 
A comparison of our American shell with specimens of the true 
7. Kriyeri, from the coast of Norway, sent to me by Dr. Friele, 
shows that they are two entirely distinct species.
