Crustacean Fauna of South Africa. 135 



First gnathopod, 6th joint f length of 5th, both joints linear, 

 densely setose but without special armature. 



Second gnathopod similar, but longer and more slender. 

 First peraeopod, 4th joint linear, not expanded or produced, 6th 

 twice length of 5th and not quite half 4th, finger longer than 5th and 

 6th together. 



Second peraeopod similar, but 4th joint slightly expanded (elongate- 

 ovate), not produced, strongly setose. 



Third peraeopod, hind margin of 2nd joint with a strong lobe-like 

 expansion, anterior apex of 4th and 5th each with one long spine-seta, 

 posterior apex of 5th with 2 long unequal spines, anterior margin of 

 5th with regularly spaced setae, posterior margin with 4 short stout 

 spines, 5th a little longer than 3rd and 4th together, 6th shorter than 

 5th but longer than 4th. 



Fourth peraeopod, posterior margin of 2nd joint evenly curved, 5th 

 as in 3rd peraeopod, but anterior margin with 6 large and several 

 smaller spines, anterior apex with 3 spines, posterior apex with 3 long 

 and 2 short spines, 6th as in 3rd peraeopod. 



Fifth peraeopod, 2nd joint evenly expanding distally, distal margin 

 nearly transversely truncate, posterior apical angle rounded, reaching 

 to end of 3rd, which is twice length of 4th, 4th not expanded, but 

 anterior apex shortly produced, 5th subequal to 4th, anterior apex 

 very shortly produced, 6th nearly equal to 3rd and 4th together, oval, 

 twice as long as broad, with 2 short spines on anterior apex, 7th equal 

 in length to width of 6th, ovate, tapering rather rapidly to a fine point. 



First uropod, peduncle and rami subequal, upper margin of peduncle 

 spinose. 



Second uropod stouter, peduncle longer than ranii, upper margin 

 with 3 pairs of spines, apex with a group of 3 spines, outer ramus a 

 little shorter than inner, inner margin with 4 spines and a long spine 

 near the apex, inner ramus with both margins spinose. 



Third uropods, peduncle with 1 spine on middle of inner margin, 

 ranii subequal, lanceolate, outer with both margins setose, the setae 

 on inner margin springing from rather deep inlets, inner ramus 

 broader, inner margin with small spiuules and a tuft of setae on apex. 



Length : 12 mm. 



Colour : In spirit, yellowish.
