Crustacean Fauna of South Africa. 181 
1 ovigerous 2. s.s. “ Pieter Faure.” 27/8/03, 20/8/03 and 4/4/01. 
(S.A.M. Nos. A221, A222 and A240 respectively). 
Geogr. Distribution: Cape Finisterre, 363-510 metres (Chevreux : 
grimaldii) ; Bay of Biscay, 950 metres (Bonnier: elegans). 
There can be little doubt that these specimens are assignable to 
Chevreux’s species, and that elegans is the ¢ of grimaldii. The 
presence of a small tooth on the 7th peraeon segment in the ¢ and 
the fact that the teeth on the pleon are not upturned are not enough 
to separate the Cape specimens from the North Atlantic ones. 
RHACHOTROPIS PAENEGLABER N.. Sp. 
(Plate XXVII. Fig. 10.) 
Rostrum reaching half way along Ist joint of Ist antenna. Eyes 
absent. Antero-lateral angles of head obtuse. 
Peraeon not keeled. Side-plates as in the previous species, but 
7th not so long proportionately to its depth and not narrowed so 
much posteriorly. Pleon segment 1 with very obscure median keel 
on posterior margin, segment 2 with 3 keels ending in small acute 
teeth, segment 3 with 3 keels not ending in teeth, segment 4 tri- 
carinate, the median keel ending in a tooth, the subdorsal keels not 
reaching the posterior margin. Postero-lateral angles of segment 3 
rounded and serrate, the margin above also serrate. 
Telson narrow, of nearly even width throughout, apices acute, not 
quite contiguous, cleft for 4 its leneth. 
First and second antennae subequal, extending in ¢ to end of 8rd 
pleon segment, in ? to end of peraeon, peduncle with calceoli and 
groups of setae, flagella of both antennae ca. 17-jointed in @, ea. 
10-jointed in 9 , accessory flagellum of Ist antenna minute but distinct. 
Mouth parts normal; mandible with the cutting-edge as in 
R. grimaldi, and 3rd joint of palp a little longer than 2nd. 
First and second gnathopods, palm defined by a well-marked obtuse 
projection bearing 6-8 spines, lobe of 5th narrow. 
Third to 5th peraeopods, 2nd joint with entire hind-margin, in 
peraeopod 5 very faintly serrate and setulose, postero-inferior angle 
quadrate (as figured by Chevreux for R. proxima), distal joints of the 
peraeopods lost. 
Length: 10 mm. 
Colour: In spirit, pale pinkish. 
Locality: Cape Point E. by N., distant 29 miles. 250-300 fathoms. 
366,16 2 2 ; Cape Point N.81°E., distant 32 miles. 400 fathoms.
