208 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
the lateral teeth of the front are a little more divergent than in 
the female, so that, in my opinion, it is only to the second dif- 
ference observed by Dr. Richters that some value can be attached. 
I, however, accept his opinion that the Mergui examples represent 
a local variety of D. wnidentata. 
The median tooth of the front, which is acute and veneicalie 
deflexed, is scarcely visible when the carapace is viewed from 
above. The upper surface of the cephalothorax is minutely 
punctate. 
The cephalothorax of the female specimen, which bears 
eggs, is 23 millim. long and 22 millim. broad. It is covered 
with a large sponge, which is much larger than the Crab 
itself. 
Dromidia unidentata has been recorded from the Red Sea and 
from Mozambique. 
118. Dromipia CRANIOIDES, n. sp. (Pl. XIV. figs. 6-8.) 
A large male and a much smaller specimen of the same sex 
were collected, the latter at Elphinstone Island Bay; but the 
exact locality of the former is unrecorded. 
This new species is most closely allied to Dromidia caput 
mortuum, M.-Kdw. (Hist. Nat. des Crustacés, t. 1. p. 178); but, 
according to Prof. Milne-Edwards, who compared the larger 
specimen with his Dromidia caput mortuum, it differs from it 
in the front being a little less advanced, by the internal 
angle of the upper orbital margin and the infraorbital lobe 
being acute, by the protogastric lobes being not at all prominent, 
by the denticulation of the antero-lateral margins, and by the 
hands being somewhat spinulose. | 
The cephalothorax is nearly semiglobose and scarcely longer 
than broad, the proportion of the length to the breadth (distance 
between the last antero-lateral teeth) being as 28:27. The 
upper surface is semiglobose, extremely convex in all directions, 
and its sides therefore slope very steeply to the lateral margins. 
No divisional lines are found on the upper surface of the cepha- 
lothorax except the usual incision in each lateral margin, sepa- 
rating the antero-lateral from the postero-lateral margins, and 
forming the so-called cervical suture. The upper surface, indeed 
the entire animal, with the exception of its fingers, is covered 
with a short, close, velvety pubescence. The upper surface is 
quite smooth to the naked eye, but is seen to be minutely
