122 A. A\GOGk-r Carcinological Fauna of India. [No. 1, 



Anterolateral border cut into five conical teeth between which are 

 granules or little denticles ; postero- lateral borders strongly convergent, 

 shorter tlian chords of antero-lateral borders. 



Clielipecls unequal : upper and outer surfaces of wrist strongly- 

 wrinkled and pitted ; upper surface of hand nodular, upper half or more 

 of outer surface of hand longitudinally ridged and transversely wrin- 

 kled : fingers short, stout, hollowed (but not broadened) at tip. 



Legs with carpus and propodite longitudinally ridged and grooved 

 above — the carpus more distinctly so — and dactylus furred. 



Side wall of carapace, edges of upper surface of arm, and edges of 

 legs — but especially upper edge of meropodites — hairy. 



Colours in spirit : yellow, fingers and .front lower corner of hand 

 blackish brown. 



Length of carapace 105 millirn., breadth 16 rnillim. 



In the Indian Museum are 45 specimens from Galle and 1 from 

 Mergui (Marine Survey). 



This species, though strongly resembling midipes and crassimanuSj 

 is at once recognized by the sharp-cut Actgea-like sculpture of the cara- 

 pace. It is possible that it may be the Chlorodius eudorus of Milne 

 Edwards. It has the closest possible resemblance to the Xantho 'quin- 

 quedentatus of Krauss, Sudfifr. Crust, p. 30, pi. i. fig. 3, but that species 

 is described and figured as having sharp fingers. 



49. Xantho (Leptodius) cavipes (Dana).

Leptodius cavipes, de Man, Journ. Linn. Soc, Zool., XXII. 1887-88, p. 34. 



Carapace convex in anterior two-thirds, flat behind. Gastric region 

 convex, well delimited and areolated by fine smooth rather deep 

 channels ; wings of carapace divided into about five lobules by less deep- 

 cut and less smooth channels : the whole carapace (except the channels) 

 covered with miliary granules, which on the lateral lobes of the gastric 

 region are arranged in lines that have an imbricate look. 



Front bilaminar, the fore edge of the lobes thickened and granular. 

 Anterolateral border thickened and granular, cut into small irregular 

 teeth — 8 or 9 in number — which fall into 4 sets. Undersurface of 

 carapace with short fur. 



Chelipeds unequal : upper and outer surface of wrist and hand 

 wrinkled and granular, outer surface of hand covered with granules in 

 more or less distinct lines : fingers little toothed, incurved, blunt-pointed 

 and hollowed (but not broadened) at tip.
