South African Crustacea. 79 



fifth joint or carpus, which in turn is a little longer than the slender 

 chela ; proportions, quite unlike those in the two species above com- 

 pared ; the fingers close tightly together and are subequal in length 

 to the palm ; there are several groups of setae on the fixed finger, 

 and a group near the apex of the carpus. The fourth and fifth 

 peraeopods are nearly alike, the long fourth and sixth joints sub- 

 equal in length, but decidedly less than twice as long as the fifth 

 joint without reckoning the little lobe by which that overlaps the 

 sixth ; the finger is very small and curved, about a tenth as long as 

 the sixth joint. A little tooth precedes its upturned point, but this 

 may be in preparation for the moult. 



The first pleopod has a very short inner branch. The branches of 

 the uropods are broad, the outer one a little the longer, much 

 extended beyond the little apical tooth of the outer margin. 



Total length 32 mm., carapace with rostrum 12-5 mm. 



Locality. Cape Natal N. by E. 24 miles ; depth 440 fathoms. 

 A 1275. 



The specimen had a very uninviting appearance, as if covered in 

 all directions by a sort of scurf. This, however, was easily removed, 

 and eventually proved to consist chiefly of the ova of some Epi- 

 caridian, together with the larvae in great numbers, minute objects 

 considerably less in total length than half a millimeter, otherwise in 

 close agreement with the figures given by Sars (Crustacea of Norway, 

 vol. 2, pi. 94) for the male larvae of Dajus mysidis (Kroyer) .
