Crustacean Fauna of South Africa. 157 
Fifth peraeopod, 2nd joint obliquely truncate, inferior angle rounded 
and reaching to end of 3rd, 3rd longer than 4th, anterior apex bevelled 
off, with 5 spinules, 4th narrowly produced half way along the anterior 
margin of 5th, 5th longer than 4th, 6th equal to 4th and 5th together, 
7th equal to 6th, tapering gradually. 
First uropod, rami subequal, longer than peduncle, margins of 
peduncle sparsely spinose, inner ramus closely spinose, outer unarmed. 
Second uropod, rami subequal, shorter than peduncle, both margins 
of peduncle and both rami spinose. 
Third uropod, peduncle with 2 spines on inner margin, rami 
elongate-lanceolate, outer quite slender, confronted margins feebly 
setose. 
Length: 14mm. and 10 mm. 
Colour: In spirit, pale pinkish. 
Locality: Umhloti River mouth NW. 4 W., distant 15 miles 
(Natal). 100 fathoms. 1 ovigerous 2 and 1 young; Beacon E. of 
East London N. ¢ E., distant 10 miles. 52 fathoms. ¢ 4 and 
ovigerous ? ?. s.s. “ Pieter Faure.” 19/12/00 and 12/7/01. (S.A.M. 
Nos. A2760 and A2747.) 
This species is very near A. spinipes Boeck, but differs in the 3rd 
and 4th pleon segments and the lst gnathopod. 
AMPELISCA NATALENSIS n. Sp. 
(Plate XXVI. Fig. 7.) 
Except for the serrate outer ramus of 3rd uropods these specimens 
are very near to the figures of A. serraticaudata Chevreux. Della 
Valle in 1893 unites serraticaudata with rubella Costa, and in 1900 
Chevreux (Rés. Camp. Monaco vol. 16, p. 44) adopts this synonymy. 
But Chevreux’s figure of the 2nd joint of 5th peraeopod of his species 
is utterly different from Della Valle’s figure of that of rubella. There 
is also a difference in the eyes, the corneal lens being apparently 
present in serraticaudata, but absent in rubella. 
As there still remains some doubt, therefore, with regard to 
Chevreux’s species, I consider it best to institute a new one for the 
present specimens. 
Corneal lens distinct, small, the lower in the antero-inferior angles 
of head, 4th pleon segment slightly indented basally, keel rising 
gradually, its upper margin straight, posterior end rectangular, 
postero-inferior angle of 3rd pleon segment with a slightly produced 
point.
