TO INDIAN CAKCINOLOGY. 353 



from the Red Sea, in the British Museum, which I have examined, the carapace and 

 chelipedes are covered with numerous small depressions or pits, giving them a rugose 

 appearance, and this character is wanting in the present species ; otherwise the two 

 are nearly related. 



Distribution. Malabar (A. Milne-Edwards). 



40. Atergatis dilatatus, De Haan. 



A. dilatatus, De Haan, Crust Japon. p. -16, tab. xiv. fig. 2 (1850). 



Ceylon (Halt/). 



I refer some young specimens doubtfully to this species. Miiller has had similar doubt 

 in regard to specimens from Trincomali. 



Distribution. China (De Haan) ; New Caledonia (A. Milne-Edwards). 



Genus Carpilius, Leach. 



41. Carpilius maculatus (Linn.). 



C. maculatus (Linn.), A. Milne-Edwards, Nouv. Arch. Mus. Hist. Nat. t. i. p. 214 (1865). 



Ceylon (Haly, Necill). 



Distribution. From Mauritius to the Malay Archipelago, New Caledonia, and the 

 Pacific. 



Genus Carpilodes, Dana. 



42. Carpilodes tristris, Dana. 



C. tristris, Dana, Crust. U.S. Explor. Exped. vol. i. p. 193, pi. ix. fig. 7 (1852). 



Muttuwartu Par, a male (Thurston). 



Distribution. Paumotu Archipelago (Dana) ; N. and N.E. Australia (Miers) ; " Eastern 

 Seas" (Brit. Mus.). 



43. Carpilodes margaritatus, A. Milne-Edw. 



C. margaritatus, A. Milne-Edwards, Nouv. Arch. Mus. Hist. Nat. t. ix. p. 182, pi. v. fig. 2 (1873). 



E-ameswaram, two males; Tuticorin, two young males (Thurston). 



These agree with A. Milne-Edwards's figure and brief description, though they have lost 

 the vivid colour shown in the former. The pearly granulations show a tendency to 

 linear arrangement on the hands. A wide hiatus exists between the fingers, and their 

 margins are toothed. The inner border of the carpus carries two strong granulated and 

 blunt teeth. The largest specimen has the carapace 17 mm. long and 27'5 mm. broad. 



Distribution. New Caledonia (A. Milne-Edwards). 



44. Carpilodes venosus (Milne-Edw.).
