Crustacean Fauna of South Africa. 139 



The rami of third uropod broadly ovate, 2 times as long as wide, 

 apices rounded (cf. those of A. pacifica Holmes). 

 Length : 10 mm. (S.A.M. No. A159.) 



AMPELISCA sp. ? No. 2. 



This specimen (Beacon E. of East London N. E., distant 10 miles. 

 52 fathoms. s.s.."Pieter Faure." 12/7/01.) differs from A. brevi- 

 cornis only in the non-produced 4th joint of 1st peraeopod, the quad- 

 rate postero-iuferior angle of 3rd pleoii segment, with a slight notch 

 and shortly produced point, and the broadly ovate ranii of 3rd uropod, 

 with apex of inner ranius hook-like and incurved. Maudibular palp 

 with 2nd joint linear, 3rd equal to 2nd. 

 Length : 8 mm. (S.A.M. No. A2748.) 

 It bears some resemblance to A. californica Holmes.

These specimens resemble the description and figures of Sars except 

 in the following points : 2nd joint of mandibular palp of nearly same 

 width throughout, the basal half being only slightly wider, 3rd joint 

 not half as long as 2nd ; outer plate of maxilliped with only 9 broadly 

 lanceolate (instead of 14 narrow lanceolate) spines ; 6th joint of 1st 

 and 2nd peraeopods proportionately longer, being almost twice as long 

 as 5th, 7th longer than 5th but shorter than 6th ; transverse rows of 

 spines on 5th joint of 3rd and 4th peraeopods fewer and containing 

 fewer spines in each ; postero-inferior angle of 2nd joint of 5th peraeo-
