variety of the present species, to which some of the figures of it cer- 
tainly bear a very strong resemblance. 
Numerous examples of clusters of cylindrical, often very much 
elongated, clusters of egg-capsules have been brought from the Grand 
Bank by the Gloucester fishermen. These, I suppose, belong to this 
species, but I have no positive evidence. The clusters are usually 
about an inch in diameter and 3 to 5 inches long. By the fishermen, 
these are called “ sea-corn” and “ green-corn.”

PLATE XLIII, FIGURE 4. 
Dredged alive, in considerable numbers, in 1877, by the U. 8. Fish 
Com. steamer “Speedwell,” off Cape Sable, N. S., in 88 to 91 fath- 
oms, on a bottom of fine compact sand, associated with Bs cyaneum 
and Sipho pubescens. Also off Cape Sable, 22 miles, 59 fathoms ; 
mouth of Halifax Harbor, 21 fathoms, 9 living young; off Halifax, 9 
to 12 miles, 42 to 92 fathoms. It had not been found so far south 
previously. These specimens all belong to a small race of the 
species. Gulf of St. Lawrence, Bradelle and Orphan Banks, 50 to 60 
fathoms,—Whiteaves. Off Metis! (coll. Dawson.) Labrador, Green- 
land! Spitzbergen, Nova Zembla, Bering’s Straits, (t. Stimpson). 
Spitzbergen, 20 to 125 fathoms,—Friele. Fossil in Post-pliocene beds 
at Riviere dn Loup, Canada, Labrador, and coast of Hudson’s Bay 
(t. Stimpson). 
Among several specimens kindly sent to me by Principal J. W. 
Dawson, dredged by him off Metis, near the mouth of the River 
St. Lawrence, some are larger than those from off Nova Scotia. The 
largest is 62"™ long; breadth, 32™™; length of aperture, 29"™; its 
breadth, 16™™.
