ciliated margins; inner ramus subequal in length to outer, with inner 
margin of first joint spined, and clothed with dense short fur, of two fol- 
lowing joints spined, the last with seven spines, which are more developed 
distally ; outer ramus suddenly contracted in width on the inner margin 
at a short distance from the base; inner margin smooth (except quite at 
distal extremity, where there are two or three-spine-like sete); outer 
margin with spine-like (annulated?) sets, and a row of similar sete pas- 
sing down the back, and ultimately passing obliquely to the distal 
extremity of the inner margin. Length half an inch. 
Only the male is known to me. One specimen, Shetland, 1863, and 
a second received from Mr. Edward of Banff.

Cumella agilis, n. sp. Male.—Pereion longer than pleon, five segments un- 
covered by carapace. Carapace longer than free segments of pereion, 
much deeper in front than behind ; no distinct rostrum ; anterior margin 
deeply concave at the side; infero-anteal corner produced and toothed ; 
teeth 2-3; surface of carapace smooth. Inferior antenne not so long 
as pereion; second joint of peduncle with a dense tuft of hair above, 
third joint also hispid. All pereiopods, except last, furnished with a 
palp of unusual structure, which has a second joint which is longer 
than the first, and slender, not setose ; then several (? five) very short 
setiferous joints which, combined, do not equal more than one-third length 
of second joint. First joint of Ist to 4th-pairs of pereiopods monstrously 
developed, long, and very massive, while the remaining portion of the 
limb is very slender ; first pair short, scarcely reaching extremity of the 
head; first joint with a long slender spine at the extremity of the hinder 
margin, fourth joint equalling in length the two following; third and 
fourth pereiopods with 2nd to 6th joints not equalling length of first; no 
whip-sete; sixth joint in form of a long slender nail. No pleopods. Tel- 
_son rudimentary, widely truncate at extremity. Uropods with peduncle 
longer than rami, a few scattered spines on inner margin ; inner ramus 
uniarticulate, longer and mueh stouter than the outer, with ten spines on 
inner margin, increasing in size distally ; outer ramus two-jointed, ter- 
minating in a long slender spine, with a minute spine on each side of it, 
no other spines or setee. Length scarcely more than an eighth of an inch.
