Crustacean Fauna of South Africa. 159 
long setae, 2nd minute, with apical setae; in ? similar, but Ist and 
2nd joints not apically produced. 
Second antenna a little longer than Ist, the two basal joints small, 
penultimate joint subacutely produced on inner (lower) apex, ultimate 
joint longer than penultimate, cylindrical, flagellum not as long as 
ultimate peduncular joint, 2-jointed, 2nd joint minute, both apically 
setose. 
Upper lip with truncate distal margin, slightly notched or excavate, 
lateral angles rounded. 
Lower lip, inner lobes absent, outer lobes apically rounded. 
Mandibles, cutting-edge, 6-dentate, secondary cutting-edge in left 
4-dentate, apparently absent in right, spine-row with 3 spines in left, 
2 in right, molar represented by a stout, pellucid spine tipped with a 
seta as long as itself, no trace of palp. 
First maxilla, outer plate with 4 stout, minutely denticulate spines, 
no inner plate or palp. 
Second mayilla, plates fused proximally but slightly separated 
distally, outer plate with 4 apical setae. 
Maxilliped, inner plate apically truncate, with 3 teeth, outer plate 
reaching to middle of apical joint of palp, outer margin convex, inner 
margin straight with a few fine setules, palp of 2 joints only, 2nd 
longer than first; inner margin being indented in middle and the 
setae disposed in 2 groups show that this joint is really two joints 
fused, though there is no trace of a suture. 
First gnathopod simple, 2nd joint with a blunt lobe on anterior 
margin subapically, anterior margin of 3rd apically produced, 4th 
triangular, smaller than 3rd or 5th, 5th not strongly lobed inferiorly, 
6th tapering, inner margin entire, setose, a short stout spine on inner 
apex, unguis curved. 
Second gnathopod similar to 1st but stouter and with anterior margin 
of 2nd joint expanded keel-like and ending before apex of joint, 
anterior margin straight. 
In 2 Ist and 2nd gnathopods similar to those of 3. 
Peraeopods gradually increasing in length posteriorly. First peraeo- 
pod somewhat similar to 2nd gnathopod, but 4th joint expanded 
anteriorly, 5th likewise expanded, transverse, posterior margin of 4th 
and 5th setose, anterior margin of 2nd keeled. 
Second peraeopod similar to Ist but in g 6th joint broader, oval- 
oblong, inner apex (‘“palm’’) strongly excised forming a rounded 
notch, apex of inferior margin projecting shortly, finger with unguis 
reaching this lobe and making the limb almost chelate; in 2 simple, 
resembling Ist peraeopod.
