The distribution of this species in South Africa is extended by the 

 discovery of specimens at the following localities : 



Swakopmund, German S.W. Africa, May, 1908 (J. Drury) ; Table 

 Bay, 26/2/14 (K.H.B.) ; Port Elizabeth, s.s. "Pieter Faure " ; Durban, 

 July, 1915 (H. W. Bell-Marley). (S.A.M. Nos. A2950, A2944, 

 A2946 and A3853 respectively.) 



The Swakopmund specimens reach a length of 15 inm. in $ , 9 mm. 

 in ovigerous $ . The hand of the 2nd gnathopod in <$ resembles that 

 figured by Mayer (1903, Siboga caprellidae, pi. 7, fig. 67) belonging to 

 a specimen from Sydney ; the finger likewise is strongly curved. 



The Durban specimens measure 13 mm. in . The finger of the 

 2nd gnathopod in $ is not strongly curved. 



I have not yet seen any specimens from the other localities in South 

 Africa to equal the Durban or Swakopmund specimens in size. 



Colour : The Durban specimens are pale whitish, with rather large 

 brownish-orange spots on the posterior half of 2nd and the whole 

 of 3rd-7th peraeoii segments and the hand of the 2nd guathopods, 

 anterior half of 2nd and whole of 1st peraeou segments finely speckled 

 with the same colour, eye brown, finger of 2nd guathopod with two 

 rings of orange. 



Geogr. Distribution : Europe ; Mediterranean ; Bosphorus : South 

 America; Sargasso Sea; Australia; Japan; Singapore; Madagascar.
