is about two-thirds as long as the hist somite and not inucii more than twice as 

 long as its greatest width. Tlie endopodite is not quite so much curved as in, 

 C. forjicnla and the exopodite is nearly straight. There are four spinules on the 

 inner edge of the endopodite, and about six, interspersed with fine sette, on that of 

 the peduncle.

CuMELL.^ LEPTOPUS, sp. n. (Plate XXXII. figs. 11-14.) 



Description of adult Male. — Total length 2'2 mm. 



Carapace about one-third of total length, its depth a little more than half of its 

 length. Dorsal edge very slightly sinuous, without spines. The eye is very large, 

 with about seven large and prominent corneal lenses, of which one is in the middle 

 line in front of the ocular lobe ; in all the specimens examined the eyes are without 

 conspicuous pigment. The pseudorostrum is practically obsolete, the lateral plates 

 apparently not meeting in front of the ocular lobe. The antero-lateral margin is 

 concave, and the angle, which is slightly prominent, is rounded. The last somite of 

 the abdomen is less than two-thirds as long as the preceding, and is produced and 

 pointed posteriorly. The lateral grooves are distinct on all the abdominal somites 

 except the last and the antennal fiagellum is about as long as the body. 



The antennules have the peduncle rather slender, the last segment being about three 

 times as long as thick, and the inner fiagellum minute and unsegmented. 



The first legs have the basis about equal in length to the remaining segments and 

 the propodus two and a half times as long as the dactylus. The second legs have the 

 distal segments slender, and the carpus more than twice as long as the merus. 



The posterior legs are very slender. The last pair are a little shorter than the 

 carapace and have the basis about two-thirds as long as the remaining segments ; the 

 carpus is about three-fourths as long as the basis and four times as long as tiie merus. 



The uropods are long and slender ; the peduncle is more than twice as long as the 

 last somite and has about nine spines on its inner edge ; the endopodite is less than 

 half the length of the peduncle, with a long slender apical spine and six spines on the 

 inner edge ; the exopodite is about five-sixths as long as the endopodite and its terminal 

 spine is very long and slender.
