402 ME. J. E. HENDERSON— A CONTEIBUTION 



Genus Myra, Leach. 



183. Mtea pugax (Fabr.). 



M.fugax (Fabr.), Bell, Trans. Liun. Soc. vol. xxi. p. 296 (1855). 



Eameswaram {Thurston, J. B. H.) ; Ceylon [Haly) ; Gulf of Martaban [Oaies). 

 In most of the specimens I have examined there is a distinct median roAV of granules 

 on the caraj)ace. 



Distribution. Mascarenes, Malay Archipelago, China, Japan. 



184. Myra australis, Haswell. 



M. australis, Haswell, Catal. Austral. Crust, p. 122 (1882) ; Miers, ' Cliallenger ' Bracliyura, p. 315 

 (1886). 



Gulf of Martaban, four males (Oates). 



These agree on the Avhole with the description, and with specimens in the British 

 Museum from Australia. The granules on the carapace are most strongly marked along 

 the median line, so as to give rise to a semicarinated appearance ; as noted by Haswell, 

 the intestinal region is capped by a cluster of granules, one of Avhich is more prominent 

 than the rest. I do not think it can be the young of 31. mamillaris. Bell, as suggested 

 by Miers, for the hejiatic regions are quite different in the two forms. 



Distribution. N. Australia {Saswell, Miers). Singapore [Walker). 



Genus Ebalia, Leach. 



185. Ebaiia Pfefferi, De Man. 



E. Pfefferi, De Man, Brock's Crust, p. 390, taf. xvii. fig. 4 (1888). 



Muttuwartu Par, a female with ova (Thurston). 



The surface is everywhere finely granulated, and the carapace rises immediately 

 behind the front to form a convex swelling, the smaller elevations on which are less 

 distinct in my sjiecimen than indicated in De Man's figure, or seen in a specimen from 

 Mauritius in the British Museum. The fingers are slightly shorter than the palm. The 

 abdomen is covered externally with smooth rounded granules. This species comes very 

 neav and is perhaps not distinct from Ebalia {Nucia) speciosa, Dana, from the Sandwich 

 Islands. 



The carapace is 11 mm. long and 12 mm. wide. 



Distribution. Amboina {De Man) ; Mauritius {Brit. Mus.). 



186. Ebalia fallax, n. sp. (PI. XXXVIII. figs. 4-C.) 



Muttuwartu Par, a female {Thurston) ; Gulf of Martaban, a male {Oates). 



The carapace is very convex, with the hepatic areas deeply excavated, and the surface 

 everywhere covered with circular flat-topped polished tubercles of varying size, which 

 are closely crowded in most places, bvit in the hepatic hollows are few and small. On 

 either side of the carapace, bounding the hepatic hollow, is a rounded granulated swell- 

 ing ; the remainder of the lateral margin is simply rounded, and without teeth or
