34 DISCOVERY REPORTS 



Mandible without molar, palp set far back. Maxilla i, inner lobe without setae, palp 

 minute, i-jointed. Maxilla 2, both lobes slender, with 1-2 apical setae. Maxilliped, 

 outer plate apically subacute, inner distal margin shallowly excised, 4th joint of palp 

 quite rudimentary. 



Gnathopod 1, 6th joint shorter and narrower than 5th, ovate. Gnathopod 2, 6th 

 joint distinctly shorter than 5th, only about two-thirds its length. 



Peraeopods 1-5 in general similar to those ofpepinii, but hind margin of 2nd joint of 

 peraeopods 3-5 quite smooth; 5th joint abruptly narrower than the expanded 4th. 



Uropods 1 and 2 biramous, rami smooth. Uropod 3 consisting of a rather stout 

 conical peduncle, without trace of rami.

Remarks. This appears to be the only occasion on which this species has been taken 

 in this area since the 'Challenger' took a small specimen off Cape Virgins. The speci- 

 mens do not differ in any respect except size from South African specimens. The <3 is 

 not fully adult as the 2nd antennae are not longer than in the ?. The eyes are dark. 



The distribution is rather remarkable and it might perhaps be worth while to re- 

 examine the East African specimen (Walker, 1909, p. 327) to see whether it is not really 

 referable to the Cingalese species tenuipes. 



Distribution. Australasia; South and East Africa; Cape Virgins, 55 fathoms. 



Genus Cyphocaris, Boeck. 

 Schellenberg, 1926, p. 243; 19266, p. 202. 



Schellenberg in the ' Valdivia ' Report has discussed the value of the specific characters 

 of the species in this genus, and has shown that certain characters undergo considerable 

 change during growth. 



C. richardi must certainly be regarded as the least specialized, followed by anonyx 

 The prolongation of the 2nd joint of peraeopod 3 and the enlargement of the 6th joint 

 of peraeopods 1-4 is a further development of a line of evolution already indicated in 

 certain examples of richardi. 



The three species bouvieri, chaUengeri and faurei are closely related to one another, 

 much more so than to richardi and anonyx. The transformation of the 2nd joint oi
