Tuticorin, a female; Miittuwartu Par. hvo males {Thurston); Rameswanim, seveml 

 specimens (/. B. II.). 



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

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

 and anterior half of the lateral margin of the carapace edged with l)rown, as in T. n'K/ri- 

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

 and distally, while brown spots arc^ ap])arent at the distal end of the meri and propodi of 

 the ambulatory legs. The pit or IioIIdm, characteristic of T. cacimana, Heller, and 

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

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



Distributwu . Red Sea. Natal, Mascarenes, Malay Arcbiiielago, Australian seas, Pacific. 



Genus Eriphia, Latr.

E. Icevimana (Latr.), De Man, Mergui Crust, p. 08 (1887). 



EamesAvaram and Tuticorin, many specimens [Thurston); Ceylon {Halij, Necill); 

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

 [J. R. H.). 



All the specimens I have exaniiiied belont^- to the tvpical form, none showiii"- auv 

 trace of granulation or tuberculation on the outer surface of the laro'cr 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 leno-th and 72 mm. in 

 breadth ; the propodus of the right chela 62 mm., measured along its lower l)order. 



Distribution. East Africa and Natal, Mauritius, Malay ArchipeUii>o, China, .Tanan, 

 N. Australia, Pacific.
