16 The Malacostraca of Natal 
exhibits a large chela just like one received from Durban in connection 
with the species now under consideration. Milne-Edwards gives the 
reference to Herbst for this Cancer vocans minor? as plate 1, fig. 1, 
instead of fig. 10. Figures 1-7 on Herbst’s first plate illustrate his 
quotation from Réaumur. His figure of C. v. minor does not show a 
very narrow front. The specimens from Durban here referred to 
de Haan’s species have the narrow front combined with a massive 
chela, which is evidently variable in details of structure, one of the 
specimens showing the remarkable widening of the apex of the fixed 
finger which Milne-Edwards has figured for his U. vocans. Apparently 
there is a similar development in U. cultrimanus (Adams and White).

Here the comparatively broad front is deflected to its apex without 
intermediate constriction. When dealing with the single specimen 
from Durban Bay sent me by Mr. Bell Marley I was tempted to 
name a new species by the armature of the fingers in the great left . 
cheliped. But other specimens, some of rather larger size, collected by 
Mr. Boyce, and subsequently received from Mr. Chubb, showed that 
no dependence could be placed on these minute characters. In de 
Haan’s figure the immovable finger projects beyond the movable, but 
that I take to be a casual variation.

In this species de Man says, ‘‘ The inferior orbital margin is simple 
in the male; but in the female it is bordered, at the bottom of the 
orbits, by an accessory row of small acute granules, close and parallel]
