South African Crustacea. 25 



Henderson says "the ambulatory legs are almost smooth, with 

 the anterior margins pubescent and very faintly toothed." In 

 our specimen the anterior margin of the carpus in the first pair 

 of walking-legs makes an exception to this statement by being very 

 distinctly denticulate. Alcock says of both pairs of walking-legs, 

 that " the anterior edge of the carpus and propodite is spinulose and 

 setose, the spinules of the carpus being the most distinct." In 

 these limbs and the two following pairs there appear to be on the 

 under side of the basal joints little pads of a rasp-like character, like 

 those on the hands of the fourth and fifth legs and on the uropods. 



Length of carapace about 9 mm.

Faxon, in 1895, is inclined to regard this species as, at most, but a 

 geographical race of the Polycheles granulatus, which he himself 

 described in 1893. The South African specimens differ in some 

 particulars from both accounts, but until more material is available 

 I am unwilling to take the responsibility of instituting a new species.
