Crustacean Fauna of South Africa. 261 
Mandibles, cutting-edge 5-dentate in left, 7 in right, secondary 
cutting-edge in left 8-dentate, 9 in right, spine-row with 9 spines, 
molar somewhat conical, palp slender, Ist and 2nd joints subequal, 
3rd not enlarged, shorter than 2nd, only the 38rd bearing setae, which 
form an apical tuft. 
First maxilla, inner plate broad with 1 apical seta, outer plate with 
10 spines, palp slender, 2nd joint narrow, curved, with apical spinules. 
Second maxilla, plates equal in length, inner narrow and more 
tapering than outer, its inner margin setose. 
Maxilliped lke that of Ampithoe, outer plate reaching to middle of 
3rd joint of palp, inner margin with ca. 13 spines. 
First gnathopod similar in both sexes, 2nd joint not lobed on 
anterior apex, 5th and 6th joints not lobed, cylindrical, their inferior 
margins setose, 6th a little longer than Sth, of nearly uniform width, 
distal margin between acute inferior apex (“thumb”) and hinge 
angularly concave, a row of setae along the thumb, finger a little more 
than 4 6th, inner distal margin with 3-4 serrations. 
Second gnathopod similar to Ist, but 5th and 6th joints a little 
stouter, and inferior margin of 5th is lobed, similar in both sexes. 
First and second peraeopods, 2nd joint expanded, ovoid, distal half 
wider than proximal, glandular, tapering, finger half length of 6th, 
inner margin smooth. 
Third peraeopod shorter than Ist and 2nd, 2nd joint ovoid, 
narrowing distally, 5th a little shorter than 4th, 6th longer than 4th, 
with 3 spines on posterior margin (anterior when in its natural reverted 
position) and 2 on posterior apex, finger and unguis short, curved. 
Fourth peraeopod longer than 3rd, 2nd joint not greatly expanded, 
but stout, half as long again as broad, 4th longer than 5th, 6th subequal! 
to 4th, 4 spines on anterior margin and 2 on anterior apex, finger and 
unguis moderately curved. 
Fifth peraeopod longest, oar-like, all the joints very stout and 
expanded, more so in ¢ than 2, 3rd not very expanded but distally 
lobed, 5th a little longer than 4th, 6th equal to 4th in ¢, equal to 5th 
in 2, considerably narrower than 5th joint, its outer margin with a 
subapical and an apical tuft of setae, inner margin with 2 subapical 
groups consisting of 1 spine and several setae, and an apical one of 
3-4 spines and setae, finger moderately curved; the whole surface 
of this peraeopod in both sexes minutely granulate, so that the margins 
of the joints appear very finely crenulate. 
First uropod, peduncle longer than rami, of which outer is shorter 
than inner, 5 marginal spines on outer, 2 on inner ramus, both rami 
with 3 apical spines.
