208 DR. J. G. DE MA.:!f 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. Eichters that some value can be attached. 

 I, however, accept his opinion that the Mergui examples represent 

 a local variety of D. unidentata. 



The median tooth of the front, which is acute and vertically 

 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. 



Drqmidia unidentata has been recorded from the E-ed Sea and 

 from Mozambique. 



118. Deomidia ceanioides, n. sp. (PI. 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 

 mor^Mwm, M.-Edw. (Hist. Nat. des Crustaces, t. ii. 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, hj 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
