R. DOUGLAS LAURIE—BRACHYURA. A451 
of the posterior half are closely covered with small rounded granules (smaller 
and more numerous than in C. areolata (H. M.-Edw.)). The areole of the 
anterior half of the carapace have a more lumpy surface, they are more 
prominent and end more abruptly in their anterior portions, but slope off 
eradually posteriorly, and the granules covering them have also their more 
prominent part directed anteriorly and the dorsal surface planed off, as it 
were, posteriorly, so as to slope gradually backwards; the granules also 
are more irregular in size on the anterior part of the carapace, larger ones 
tending to cluster at the anterior margins of the areole, as may be well 
seen, for example, in 2 I’, where an appearance is produced which contrasts 
markedly with the rounded character of the same areole in C. areolata. 
The dividing channels are naked; they are smooth in front of the cervical 
groove, but tend to be obscurely granular behind this. There is no hair on 
the dorsal surface of the carapace, except a bristle or two here and there. 
The front is distinctly and broadly cut by a U-shaped notch into two lobes, 
the outer angle of each of which forms a separate lobule. The free margin 
of the large inner frontal lobes bears a neat row of bead-like granules. 
The three fissures of the granular orbital margin are well marked, giving 
a lobed appearance. 
The antero-lateral border is divided into four rounded-triangular lobes, in 
addition to the outer orbital angle, of which the third is the most prominent. 
The greatest breadth of the carapace is therefore across this region. 
All the areolze of Dana’s scheme are clearly visible and some of them are 
further subdivided : 2 M is divided by a longitudinal groove into a smaller 
inner and a larger outer portion, 6 L is subdivided into two, the tooth 8 is 
distinct from the areola 1 R, 2 BR is divided into two; the narrow median 
anterior process of 8M runs forward between the posterior portions of the 
inner borders of 2 M, 1 P is shaped as in C. areolata, having a median notch 
anteriorly, corresponding with the median posterior projection. 
The epistome is smooth, the sub-hepatic and sub-branchial regions are 
granulated, as also the sternum between the chele; granulation becomes 
obscure and pitting mingles with it on the sterna between the walking-legs. 
All these regions are naked or practically so. 
There is an inconspicuous granulated sub-hepatic tubercle. 
The outer distal angle of the basal antennal joint is drawn out into the 
large orbital hiatus, so as to lie against the inner angle of the lower orbital 
margin, but it falls very far short of filling the hiatus; the inner distal angle 
falis short of the hiatus and slopes obliquely where it comes in contact with 
the turned-down outer frontal lobe. The antennal flagellum arises from the 
basal joint where the latter makes an angle with the outer frontal lobe, and 
so lies in the hiatus. 
The exposed surface of the external maxillipedes is naked, but the inner 
margin of the ischium has a short fringe of delicate hairs, very different from
