60 S. I. Smith — Crustaceans of the Atlantic Coast. 
The subdorsal carinte are distinct and distinctly, and pretty regu- 
larly, dentate throughout. The superior lateral carinae are better 
marked than in the last species and terminate in an acute and prom- 
inent tooth at the outer margin of the orbit, and just back of this 
there is a distinct tooth in the carina itself. The elaborate sculptur- 
ing of the dorsal surface of the abdomen, though apparently after 
the same pattern as in septemcarinata , is much more distinct and 
conspicuous. 
The telson, in all the specimens seen, reaches to or slightly beyond 
the tips of the inner lamellae of the uropods. The distal portion is a 
little more slender than in the last species and the dorsal aculei ap- 
pear slightly more conspicuous. In adult specimens, the extremity 
terminates in an acute tip much longer than its breadth at base, 
where it is separated from the body of the telson by an emargination 
each side, from each of which arise two spines, a large inner one with 
a minute one outside at its base ; this is the structure in the two per- 
fect adult specimens examined, the larger of the two females from 
the coast of Norway (Plate XI, figures 6 6, 6c) and a smaller individ- 
ual of the same sex from the Gulf of Maine, 1877, (Plate XI, figure 
7). In a very small specimen, only 16 mm in length, from St. George’s 
Banks (Plate XI, figure 8), and in a still smaller specimen from Le 
Have Bank, the extremity of the telson is acutely triangular and 
armed each side with three slender spines of nearly equal length, — 
evidently an approach to the early stages of the young. 
St. George’s Banks !, 60 fathoms, shells and sand, 1872, — one young 
specimen 16 mm in length. Gulf of Maine!, about east-southeast from 
Cape Sable, Nova Scotia, latitude 42° 40' north, longitude 66° 58' 
west, 112 fathoms, gravel, August 20, 1877, — one female 36 mm in 
length. Le Have Bank !, 60 fathoms, coarse gravel, stones and 
sponges, September 12, 1872, — a female, 47 mm in length, carrying 
eggs, and a small specimen badly mutilated. Lofoten Islands!, coast 
of Norway (G. O. Sars), — two fine females, 62 and 53 ram in length. 
I take great pleasure in associating the name of Professor G. O. 
Sars with this species.
