'240 Annul* of the South African Mnxeuin. 



longer, mandible with 5 spines in spine row, palp with 3rd joint sub- 

 equal to 2nd, in its distal half rather suddenly contracted, apex acute, 

 distal half of inner margin setiferous, outer plate of maxilliped reach- 

 ing to end of 2nd joint of palp. 



First gnathopod, 6th joint with submarginal groups of setae, 

 inferior margin with 2-3 faint serrations, finger longer than in 

 Haswell's figure, inner mai'gin smooth. 



First and second peraeopods, finger length of 6th joint. 



Postero-lateral angles of 3rd pleon segment quadrate. 



Length : 7 mm. 



Colour : In spirit, pale pinkish. 



Locality : Umvoti Elver mouth N. by W. J W., distant 15 miles 

 (Natal). 56 fathoms. 1 <J . s.s. " Pieter Faure." 8/1/01. (S.A.M. 

 No. A176.) 



Were it not for the pi'esence of the ventral spines, I should not 

 hesitate to identify this specimen with Lemboides australis (Haswell). 

 Thinking that these spines might have been overlooked, I appplied to 

 Prof. Haswell, who kindly looked through the Crustacea in the 

 Macleay Museum, Sydney, but failed to find either the type or any 

 specimens of the species in question. Dr. E. A. Briggs also obliged 

 me by examining the collection in the Australian Museum, without 

 any better result. So that oue must regard the type of Haswell's 

 Microdeutopus australis as in all probability lost, and institute a new 

 species for the South African form.
