﻿South African Cnistacea. 37 



Of the first antennae the more robust flagelluin is also the 

 longer. The stiliform extremity of the first peraeopods appears 

 to have an apical sHt. Bate speaks of the second peraeopods 

 as unequally long and slender. Each of our specimens has 

 only one member of the pair, the wrist in two instances being 

 four-jointed, in the third instance much longer and obscurely 

 multiarticulate, thus among them agreeing with Bate's 

 figures for this pair. The last three pairs of peraeopods 

 are in agreement with Bate's account, except that the curved 

 fingers, instead of only 2 teeth on the concave border, have on 

 its proximal part a series of 4 or 5 slender spines, successively 

 larger tow^ards the apex. Bate says that the first pair of 

 pleopods is single-branched. In our specimen it has a short 

 but conspicuous inner blade. The uropods are longer than 

 the telson, their rami nearly equal in length, the broader outer 

 one prolonged beyond the lateral tooth in a broadly rounded 

 apex. The narrow telson has 7 pairs of lateral spines and 

 2 pairs that are much longer on the irregularly truncate apex. 

 Total length of the specimen specially examined, not quite the 

 largest, was 23-5 mm., of which the carapace with rostrum 

 occupied a little more than 7 mm.

 Alcock distinguishes Plesionika, in which there are epi- 

 podites on the first four pairs of paraeopods, from Para- 

 pandalus which has no epipodites on those limbs, with the 

 result, as Balss points out, that Parapandalus longirostris, 

 Borradaile, must be transferred to Plesionika.
