slender set, as long as the median antenne. The palpi are slender, 
longer than the antenne ; lateral feet prominent, projecting beyond the 
scales; sete light yellow. 
Color variable, generally light gray, with a dark brown median dorsal 
band, each scale often bordered on the posterior and inner edges with 
brown, which is connected with a blackish angular spot near the ante- 
rior margin, the rest of the scale being transparent and whitish; head 
dark brown, with a red central spot and a round whitish spot on each 
side. Length up to 150™; breadth usually about 4™™. 
Vineyard Sound, low-water mark to 14 fathoms; off Martha’s Vine- 
yard, 21 fathoms, sand; off New Haven, 4 to 5 fathoms, shelly. Great 
Egg Harbor (Leidy). 
This species differs considerably in the form of the head, antenne, 
&e., from the figure given by Leidy. His description is insufficient to 
determine whether he observed the same species.

Long Island Sound, off New Haven, 3 to 8 fathoms, mud, common ; 
off Block Island, in 29 fathoms; Bay of Fundy, 10 to 60 fathoms. 
This species is readily distinguished by the form of the head and 
position of the small antenn; by the large median dorsal papilla on the 
proboscis, and the smaller ventral one; by the very prominent and widely 
separated rami of the posterior feet; and the dark color of the sete. 
It grows to the length of 130™™ or more.

Vineyard Sound, 8 to 10 fathoms, shelly ; Watch Hill, Rhode Island, 
4 to 5 fathoms, among rocks and sand. Massachusetts Bay (Ehlers). 
This species is remarkable both for the form of the head and the 
length of the sets, which often exceed the diameter of the body.

Ehlers gives Edgartown as a locality for this species. Itisa northern 
form, found at Iceland, Greenland, Spitzbergen, and along the northern 
coasts of Europe and Great Britain. Stimpson records it from the
