Carcinological Fauna of India. 207 



the buccal frame or of the external maxillipeds can be seen in a dorsal 

 view even in the deep incision between the frontal teeth. : 



(3) the tooth on the posterior part of the upper of the two lines 

 that defines the hepatic facet is almost as large and prominent as that 

 on the lower : 



(4) the chelipeds are quite similar in both sexes, and are stout, 

 especially the hand ; they are just under twice the length of the carapace 

 (without spine). The hand is hardly two-fifths the length of the cara- 

 pace (without spine), is more than half as broad as long, and is some- 

 what inflated ; the fingers are as long as the hand, the clactylus being 

 plainty longer than the outer border of the hand : 



(5) on the long penultimate piece of the male abdomen is a strong- 

 terminal tooth. 



Colours in spirit : regions of carapace defined by broad orange-red 

 markings, some broad orange-red cross-bands on chelipeds, one of which 

 occupies the basal half or three-fourths of the fingers. 



Carapace in the adult, male 16 millim. long and 14 millim. broad, 

 in the adult female 20 millim. long and 18 millim. broad. 



In the Indian Museum are 34 specimens from Arakan, Mergui, 

 Ganjam, and Ceylon, usually at depths of about 30 fathoms. 



In the young the intestinal region is well defined and tumid, and is 

 surmounted by a raised cluster of granules in a line with the median 

 longitudinal carina. 



The prominent front, the stout chelipeds, and the short inflated 

 hands are chai'acters by which this species is easily i-ecognized. 



44. Myra damleyensis, Haswell. 



Myra damleyensis, Haswell, Proc. Linn. Soc, N. S. Wales, IV. 1879, p. 52, pi. v. 

 fig. 4, and Cat. Austral. Crust, p. 122 : Miers, ' Challeuger ' Brachyura, p. 31G. 



Carapace sub-piriform, globous dorsally, the lateral margins full 

 and inflated and not defined by any beaded line ; the surface very finely 

 and closely granular (under the lens) ; the intestinal region fairly well 

 defined, as are also the branchial regions posteriorly. 



The three processes on the posterior margin are not spines, but 

 broadly-laminar petaloid lobes. 



The front is prominent, but the dentiform ends of the walls of the 

 branchial canals can be seen beyond it in a dorsal view : it is deeply 

 channelled in the middle line, dorsally, and has a fluted appearance : the 

 outer wall of the orbit has the same elegantly fluted appearance, owing 

 to the depth of the sutures and the convexity of the surfaces between 

 the sutures. 



Behind the front the side-wall of the hepatic regions is full and
