Crustacean Fnnn of South Africa. 157 



Mandibles, cutting-edge 4 dentate, secondary cutting-edge in left 

 with 8 fine teeth, absent altogether in right, molar not prominent, palp 

 absent. 



First maxilla, inner plate very small, without setae, outer plate with 

 6-7 spines, palp very small, with 1-2 apical setae. 



Second maxilla, plates fused at base, apically distinct, the outer 

 longer and broader than inner, with ca. 7 setae on apex, and 3 on 

 outer distal margin, inner plate apically subacute with 1 long spine 

 and 3 setules on inner margin. 



Maxilliped, inner apical angle of inner plate with 1 spiuule and 1 

 setule, outer plates with very few setules, 4th joint of palp as long as 

 '2nd and 3rd together, curved, with 1 apical seta and crenulate inner 

 margin. 



First and second gnathopods similar, 2nd joint longest, 3rd and 4th 

 joints subequal, 5th longer than 6th in 1st gnathopod, subequal in 

 2nd, 6th joint widening distally, palm nearly transverse, nearly as long 

 as inferior margin, defined by 2 spines and sparsely setose. 



First and second peraeopods, 2nd joint longest, linear, 3rd and 5th 

 subequal, 4th longer, anterior apex somewhat produced, subacute, 6th 

 a little longer than 4th, 7th half 6th, with 1 spine-seta on inner 

 margin near apex, hind-margin of 4th to 6th joints with short thick 

 pubescence. 



Third to fifth peraeopods, 2nd joint not expanded, postero-inferior 

 apex with an acute triangular tooth, 3rd joint shortest, 4th subequal to 

 2nd, hind margin distally expanded, apex subacute, distal margin 

 sinuous, 5th a little shorter than 4th, 6th longest, 7th a little more 

 than half 6th, stout and curved, with a spine seta near apex, hind 

 margin of 4th to 6th joints with short thick pubescence. All the 

 peraeopods are sparsely setose. 



Marsupial plates very large, oval, twice as long as broad, with thick 

 fringe of plumose setae. 



First and second pleopods, peduncle subrectangular, not produced, 

 inner apical angle with 4 curved spines, raini well developed, with 

 plumose setae. 



Third pleopod, peduncle as in 1st and 2nd pleopods, raini rudimen- 

 tary, short and oval, without setae. 



First uropod, peduncle stout, equal to inner ramus which is longer 

 than outer, a short blunt spine on apex of outer ramus and one just 

 before the apex of inner ramus. 



Second uropod, peduncle stout, longer thanrami, which are subequal. 



Third uropod represented only by an oval lobe-like peduncle, without 

 spines or setae.
