Crustacean Fauna of South Africa. 141 



First antenna shorter than peduncle of 2nd antenna, 2nd joint a 

 little longer than 1st, fiagellum longer than peduncle, 12-jointed. 



Second antenna nearly as long as body, ultimate and penultimate 

 joints subequal, flagellum ca. 28-jointed. 



Lower lip, lobes broad, apically rounded. 



Mandibles, cutting-edge 4-deutate, secondary cutting-edge in left 

 3-deutate, in right represented by a simple spiuit'orm process, spine- 

 row with 5 serrate spines, 2nd joint of palp linear though slightly 

 tapering distally, 3rd slender and a little longer than 2nd. 



First maxilla, inner plate with 1 subapical seta, outer plate with 

 9 spines, 2nd joint of palp with 4 teeth and 4 spines. 



Second maxilla, plates subequal in width, apices rounded, outer 

 plate rather broader distally than proximally. 



Maxilliped, outer plate rather narrow, inner margin with 6 ovate 

 spines, palp rather slender, 3rd joint externally a little lobed but 

 scarcely produced, 4th spiniform. 



First guathopod, 6th joint shorter than 5th, linea,r, slightly tapering 

 distally, inferior margin with very distinctly biserrate setae, 7th half 

 length of 6th. 



Second gnathopod, 6th joint half length of 5th, 7th half 6th, slender 

 and furnished mostly with simple setae. 



First and second peraeopods, 4th joint not apically produced, 7th a 

 little longer than 5th and 6th combined, the 2nd but not the 1st 

 peraeopod densely setose. 



Third peraeoped, 2nd joint broader than long, anterior margin 

 evenly convex, with plumose setae, 5th a little longer than 4th , 

 posterior apex with 5 short and 2 long spines, no transverse rows of 

 spines, 6th scarcely longer than 5th with only 3-4 setae on distal 

 anterior margin, 7th stout, recurved, with 2 teeth on outer margin. 



Fourth peraeopod similar to 3rd, but 2nd joint a little longer than 

 broad, posterior apex of 5th with 7 short and 2 long spines. 



Fifth peraeopod, anterior margin of 2nd joint slightly concave, 

 posterior margin strongly expanded and obliquely truncate, plumose 

 setae not quite extending as far as junction with 3rd joint, apex of 

 2nd reaching end of 3rd, which is a little longer than 4th, anterior 

 apex of 4th slightly produced, 5th oval, as long as 3rd and 4th to- 

 gether and twice as long as broad, 6th narrow and a little shorter than 

 5th, 7th slender, spiuiform. 



First uropod, rami subequal, longer than peduncle, tapering to fine 

 points and strongly curved, unarmed. 



Second uropocl, rami subequal and equal to peduncle, reaching half 

 way along rami of 3rd uropod, sparsely spinose.
