Crustacean Fauna of South Africa. 215 



Length : 2'5 mm. 



Colour : Dull yellowish, peraeon segments 6 aiid 7 and pleon 

 segment 1 bright orange. 



Locality : Sea Point, near Cape Town. 26/2/14. (K.H.B.) ? ? , 

 some ovigerous. (S.A.M. No. A2936.) 



Geogr. Distribution : Brittany (Chevreux) ; Ceylon (Walker). 



The differences between these and Walker's Ceylon specimens 

 are to be found in the 1st side-plates, 2nd and 4th joints of peraeopod 

 3 and the plumose setae on peraepods 4 and 5. 



Walker does not specially mention the 2nd maxilla, but says the 

 mouth-parts " seem to agree with Delia Valle's figures." In the 

 South African specimens the 2nd maxilla is very different from Delia 

 Valle's figure, the inner plate being relatively smaller. 



These small differences, however, ai*e scarcely important enough to 

 separate the Ceylon and South African specimens. 



FAMILY TALITRIDAE.

Among the representatives of this family in South Africa is Orchestia 

 bottae, recorded by Krauss and retained in the General Catalogue by 

 Stebbing. It is almost certain that Krauss was wrong in his identi- 

 fication, but as I have not been able to see his specimens I cannot 

 throw any further light on this species. From the habitat given by 

 Krauss, " in algae on the coast," one would suspect it to be a species 

 of Hyale. (See Parorchestia dassenensis infra.) 



GEN. TALOECHESTIA Dana. 



1853. Subgen. Talorchestia Dana, Auier. J. Sci. ser. 2, vol. 14, p. 310. 

 1906 Talorchestia Stebbiug, I.e. pp. 543, 735 (references).

Bate's South African species T. africana still remains rather 

 doubtful owing to the elusiveness of the male. H. W. Bell-Marley, 

 Esq., of Durban, has so far been unable to find this sex, though he 

 has forwarded several females to Mr. Stebbing and to this Museum.
