decision that only one species is in question, which with great 
increase of size exhibits some small correlated variations. 
Concerning a female, in which the carapace was 70 mm. long 
by 85 mm. broad, Professor Smith remarks that it was carrying 
approximately 47,000 eggs, the eggs being nearly spherical and 
about 0°74 mm. in diameter.

It should be observed that de Haan included two species in 
his subgenus, the second of which, C. vestitus, has been referred 
to various genera, and now stands under Pzlumnoplax, Stimp- 
son. This species, which appears to be involved in some 
obscurity, is the only one of the two that McLeay and Krauss 
note as occurring in South African waters. Carcinoplax serosa, 
A. Milne-Edwards, and C. integra, Miers, are transferred to 
Kinahan’s genus Litocheiva by Alcock, who, on the other hand, 
places Wood-Mason’s Nectopanope longipes in the present genus.

Milne-Edwards in 1837 alludes to de Haan’s figure of Cancer 
(Curtonotus) longimanus as being still unaccompanied by any 
description, but notes its close apparent proximity to Pseudo- 
rhombila quadridentata (Latreille). Dana in 1852 accepts the
