Crustacean Fauna 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 spinule and 1 
setule, outer plates with very few setules, 4th joint of palp as long as 
2nd and 35rd together, curved, with | apical seta and crenulate inner 
margin. 
First and second gnathopods similar, 2nd joint longest, 3rd and 4th 
joints subequal, 5th longer than 6th in Ist 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 jomt 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, rami well developed, with 
plumose setae. 
Third pleopod, peduncle as in Ist and 2nd pleopods, rami 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 than rami, which are subequal. 
Third uropod represented only by an oval lobe-like peduncle, without 
spines or setae.
