Crustacean Fauna of South Africa. 159 



long setae, 2nd minute, with apical setae ; in $ similar, but 1st and 

 2nd joints not apically produced. 



Second antenna a little longer than 1st, 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 maxilla, 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 guathopod 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 entii'e, 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 ? 1st and 2nd guathopods similar to those of $ . 



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 1st but in 3 6th joint broader, oval- 

 oblong, inner apex ("palm") strongly excised forming a rounded 

 notch, apex of inferior margin pi-ojecting shortly, finger with unguis 

 reaching this lobe and making the linib almost chelate ; in $ simple, 

 resembling 1st peraeopod.
