188 Annals of the South African Museum. 
flagellum longer than peduncle, 17-18-joimted, accessory flagellum 
scarcely equal to 1st flagellar joint, 2-jointed, the 2nd joint minute. 
Second antenna a little more than half 1st, peduncle longer than that 
of 1st, ultimate and penultimate joints subequal, flagellum equal to 
ultimate peduncular joint, 5-jointed, Ist joint much the longest. 
Upper lip with rounded, entire distal margin. 
Lower lip, inner lobes well developed, outer lobes apically truncate, 
mandibular processes well developed, subacute. 
Mandibles stout, cutting-edges tridentate, secondary cutting-edge in 
left strong and 4-dentate, in right feeble and bidentate, spine-row with 
2-3 spines, molar prominent, palp very slender, 3rd joint shorter than 
2nd, tipped with 2 long and 1 short setae, no marginal setae on any 
of the joints. 
First maxilla, inner plate with 3 apical setae (2 long, 1 short), inner 
margin nonsetose, outer plate with 9-10 spines, palp with 2nd joint 
longer than Ist apex, with 2 teeth and ca. 8 setae. 
Second maxilla, plates equal in length, but imner narrower, and 
without setae on its Inner margin. . 
Maxilliped, inner plate apically truncate, with ca. 5 obscure denticles 
and some simple setae, a more prominent denticle and a stout spinule 
on inner apical angle, inner margin nonsetose, outer plate oval, reach- 
ing to just beyond middle of 2nd joint of palp, inner margin with 
spine-setae, palp slender, 2nd joint twice length of 38rd, which is 
longer than Ist, 4th together with its terminal unguis equal to Ist. 
First gnathopod, 5th joint oblong, not distally widened, inferior 
margin setose, 6th longer and wider than 5th, oval, palm very 
oblique, nearly 3 times as long as inferior margin, scarcely any 
defining angle, setose, a spine at 3 distance from hinge and a row of 
setae at junction with hind margin, finger equal to palm. 
Second gnathopod similar to Ist, but 5th joint strongly produced 
downwards as a triangular process, wider than 6th, and setose on 
inferio-distal margin, 6th joint as in Ist gnathopod, but inferior 
margin relatively to palm a little longer. 
First and second peraeopods not very slender, 2nd joint longest, 4th 
longer than 5th or 6th, which are subequal, 7th passing gradually into 
slender unguis, both together not quite equal to 6th. 
Third peraeopod, 2nd joint not expanded, hind margin with 
scattered setules only, not apically produced, 4th and 6th subequal, 5th 
longer, hind apex of 6th with several strong and long setae, 7th half 
length of 6th, with a fine setule on inner apex, unguis slender, straight. 
Fourth peraeopod longer than 3rd or 5th, 4th and 5th joints sub- 
equal, 6 shorter, otherwise similar to 3rd peraeopod.
