The South African specimens do not differ from the published 

 descriptions and figures of Mayer and Stebbing except in two minor 

 points. The branchial lamellae are broader and more oval. The setae 

 on the second antenna of $ are shorter and much sparser. 



Mayer in describing C. subinermis u. sp. from Japan (I.e. 1890, 

 p. 86) states, as one of the differences between the two species, that in 

 subinermis the nugues of peraeopods 5-7 are denticulate, whereas in 

 danilevsJcii they are smooth. Stebbing, however, represents them in 

 the Challenger specimen of danilevsJcii as " minutely serrulate " in 

 both descriptions and figure ; and in the South African specimens 

 they are very distinctly and regularly denticulate. 



Length : <$ 15 mm., $ 8 mm. 



Colour : Uniform green, brownish or reddish according to the colour 

 of the weed on which they are living. 



Locality : Sea Point, near Cape Town. 29/11/13. (K.H.B.) <$<$,
