 at a short distance from the base; inner margin smooth (except quite at 

 distal extremity, where there are two or three spine-like setae) ; outer

Cumetta 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 antennae 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 1st 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-setae; sixth joint inform 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 much 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 setae. Length scarcely more than an eighth of an inch.
