The distribution of this species in South Africa is extended by the 
discovery of specimens at the following localities : 
Swakopmund, German §.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 mm. in ¢, 9 mm. 
in ovigerous 2. The hand of the 2nd gnathopod in ¢ resembles that 
figured by Mayer (1903, Siboga caprellidae, pl. 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 peraeon segments and the hand of the 2nd gnathopods, 
anterior half of 2nd and whole of Ist peraeon segments finely speckled 
with the same colour, eye brown, finger of 2nd gnathopod with two 
rings of orange. 
Geogr. Distribution: Europe; Mediterranean; Bosphorus: South 
America; Sargasso Sea; Australia; Japan; Singapore; Madagascar.
