Tiiticorin, a female; MiUtuwavtu Tnr. hvo males (Tlmrdon); Uameswavam, several 

 specimens (/. R. II.). 



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

 ferred to a single variable species. Most of tlu; specimens I have observed had the front 

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

 frons, Dana, and in some the merus of the cheli[)edes carries the same colour anteriorlv 

 and distally, Avhile brown spots arc? a])parent at the distal end of the meri and propodi of 

 the ambidatory legs. The pit or hollow, characteristic of T. cacimana, LLellcr, and 

 which occurs on the outer proximal surface of the liand, is usually present, but of varyiuo' 

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



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



Genus Eriphia. Latr.

Rameswaram and Tuticorin, many specimens {Thursiou) ; Ceylon (Hal//, Nccill); 

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

 (J. B. H.). 



All the specimens 1 have examined belong to the typical form, none showing any 

 trace of granulation or tuberculation on the outer surface of the lai'ger chela, as in the 

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

 account of its large size, the carapace measuring 58 mm. in lengtli 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 Archipelago, China, Japan, 

 N. Australia, Pacitic.
