Crustacean Fauna of South Africa. I45, 
Ocular lobes much produced (but not so much as in dolichommata), 
reaching nearly to middle of Ist joint of Ist antenna. Side-plate 1 
scarcely widened below, not longer than deep, rounded antero-inferior 
angle not produced forward. Anterior lobe of side-plate 5 as deep 
as 4. Postero-lateral angles of 3rd pleon segment rounded. 
Telson as long as broad, triangular, a small spine at each postero- 
lateral angle, apex between them much produced, forming a little tail 
(as in Stebbing’s figure of dolichommata but more produced). 
First antenna, Ist and 3rd joints subequal, 2nd longer, flagellum 
shorter than peduncle, 8—10-jointed. 
Second antenna, 4th and 5th joints subequal, flagellum nearly equal 
to 4th plus 5th peduncular joints, 7-8-jointed. 
Mandibular palp with 3rd joint longer than Ist, but shorter 
than 2nd. 
First maxilla, inner plate with 1 seta. 
First gnathopod, 2nd joint not distally lobed, 3rd and 4th subequal, 
5th a trifle longer than 6th, 6th ovate, narrowing distally, palm not 
defined, 4th—6th joints inferiorly setose, 7th ¢ length of 6th, inner 
margin distally serrate. 
Second gnathopod in g, 2nd joint stout with a large ear-like 
rounded lobe on the upper outer surface, beginning just beyond the 
middle of the joint and reaching to end of 3rd joint, 3rd with a 
rounded lobe on the lower inner surface and projecting horizontally 
inwards (the limb being considered in its natural vertical position), 4th 
longer than 3rd, 5th triangular, cup-like, very short, upper apex 
rounded, setose, lower apex produced in a rounded setose lobe, 6th 
longer than 2nd, ovate, palm oblique, shorter than hind margin, 
defined by a little spinule and within this a short, blunt, squarish 
knob, a prominent triangular tooth in the middle of palm, flanked by 
shallow concavities, at base of hind margin a strong, triangular, 
pointed tooth set at right angles to the joint and pointing inwards 
like the lobe on 3rd joint, finger gently curved, reaching to middle of 
hind margin, inner margin distally obscurely serrate; in 2 2nd joint 
not very stout, without the distal ear-like lobe, 3rd not lobed internally, 
5th not so prominently lobed inferiorly, 6th oblong, palm oblique, 
concave, equal to hind margin, defining angle quadrate but not 
projecting, a little way witbin the defining angle is a low squarish 
knob, palm thence concave with a triangular pointed tooth, finger 
matching palm, very obscurely serrate distally. 
Third and fourth peraeopods, 2nd joint broadly oval, narrowing 
distally, 6th joint with a spine in middle of inner margin and another 
at apex.
