Crustacean Fauna of South Africa. '245 



Ocular lobes much produced (but not so much as in dolicJiommata) , 

 reaching nearly to middle of 1st joint of 1st 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. 



Telsou 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, 1st 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 1st, but shorter 

 than 2nd. 



First maxilla, inner plate with 1 seta. 



First guathopod, 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 iuferiorly setose, 7th f length of 6th, inner 

 margin distally serrate. 



Second gnathopod in ^ , 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 spiuule 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 $ 2nd joint 

 not very stout, without the distal ear-like lobe, 3rd not lobed internally, 

 5th not so prominent! v lobed inferiorly, 6th oblong, palm oblique, 

 concave, equal to hind margin, defining angle quadrate but not 

 projecting, a little way within 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.
