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 n. sp. from Japan (lc. 1890, 
p. 86) states, as one of the differences between the two species, that in 
subinermis the ungues of peraeopods 5—7 are denticulate, whereas in 
danilevskii they are smooth. Stebbing, however, represents them in 
the Challenger specimen of danilevskii as “ minutely serrulate” in 
both descriptions and figure; and in the South African specimens 
they are very distinctly and regularly denticulate.
