TO INDIAN CARCINOLOGY. 367 



Tuticorin, a female; Muttuwartu Par, two males (Thurston); Rameswaram, several 

 specimens (/. R. II.). 



It is very doubtful whether all the described species of this genus should not be re- 

 ferred to a single variable species. Most of the specimens 1 have observed had the front 

 and anterior half of the lateral margin of the carapace edged with brown, as in T. nigri- 

 frons, Dana, and in some the merus of the chelipedes carries the same colour anteriorly 

 and distally, while brown spots are apparent at the distal end of the meri and proporli of 

 the ambulatory leys. The pit or hollow, characteristic of T. cavimema, Ileller, and 

 which occurs on the outer proximal surface of the hand, is usually present, but of varying 

 extent. An adult measured 7'5 mm. long and 7 mm. broad. 



Distribution . Red Sea. Natal, Mascarenes, Malay Archipelago, Australian seas, Pacific. 



Genus Eriphia, Latr. 



88. Eriphia l^evimana, Latr. 



E. Icevimana (Latr.), De Man, Mergui Crust, p. 68 (1887). 



Rameswaram and Tuticorin, many specimens (Thurston); Ceylon (Holy, Necill); 

 Rameswaram, common on the reef and among blocks of dead coral between tide-marks 

 (J. R. H.). 



All the specimens I have examined belong to the typical form, none showing anv 

 trace of granulation or tuberculation on the outer surface of the larger chela, as in the 

 variety Smithii of MacLeay. A female with ova from Rameswaram is noteworthy on 

 account of its large size, the carapace measuring 58 mm. in length and 72 mm. in 

 breadth ; the propodus of the rigbt chela 62 mm., measured along its lower border. 



Distribution. East Africa and Natal, Mauritius, Malay Archipelago, China, Japan, 

 N. Australia, Pacific. 



Genus Neptunus, De Haau. 



89. Neptunus pelagicus (Linn.). 



N.pelagicus (L.), A. Milne-Edwards, Nouv. Arch. Mus. Hist. Nat. t. x. p. 320 (1861). 



Tuticorin (Thurston); Ceylon (Hal//); Bombay, Sind, Malabar, Akyab (Day). Very 

 common on the S. Indian coast (J. R. H.). 



Distribution. From the Red Sea and E. Africa to the Pacific. 



90. Neptunus gladiator (Fabr.). 



N. gladiator (Fabr.), A. Milne-Edwards, Nouv. Arch. Mus. Hist. Nat. t. x. p. 330 (1861). 



Rameswaram (Thurston); Gulf of Martaban (Gates); Ceylon (Haly). Common at 

 Madras (J. R. H.). 



A male from Rameswaram measures 26 mm. long and 48 mm. broad (including the 

 lateral spines). 



Distribution. From India to Japan and N. Australia.
