BRACHYURA. 405 



Remarks. I consider A. calculosa and A. granulata to be distinct species. 

 ( lomparing the present series of the former with a series of over 20 specimens of the 

 latter in the British Museum, I find that though the differences are individually 

 slight, they are numerous, constant and highly correlated. A series of differences 

 between the two species has been set forth by Calman (C, p. 8). 



I have seen Miers' specimens in the British Mnseum, for the reception of which he 

 made Euxanthus tuberculosus ; as Calman points out, they certainly = A. calculosa. 



Actaea granulata (Audouin, 1826) A3, p. 151. 



Localities : Off Negombo, Gulf of Manaar, two specimens ; coral reefs, Gulf of 

 Manaar, one specimen. 



Xanthias[= XanthodesJ lamarcki (H. M.-Edw., 1834) A.3, p. 157. 

 Locality : Galle, lagoon, four specimens (two adult 6 , two young ? ). 



Xanthias [= Xanthodes] notatus, Dana, 1852 A.3, p. 158. 



Locality : Chilaw Paar, one specimen. 



Description: Adult male; agrees well with Alcock's description. In comparing 

 with Dana's figure it may be noted that, both in Alcock's description and in the 

 present specimen, the last two antero-lateral teeth are procurved and spine-like. The 

 3rd tooth is in this specimen the longest. 



Chlorodiella [= Chlorodius] niger (Forskal, 1755) A.3, p. 160. 



Localities : Trincomalee, one specimen (a) ; Palk Bay, one specimen (b). 



Description : Specimen (a) is a small male (? immature), CI. = 6 '50 ; specimen (b) 

 is an ovigerous female, G.l. = 9 "25. In both examples the last two antero-lateral 

 prominences are blunt teeth (sharper than the 1st and 2nd teeth of the series in (a), 

 much as 2nd tooth in (b)). They do not terminate in " procurved spine-like points'' 

 as in the examples described by Aloock. In specimen (a) there is neither spine nor 

 tubercle on the anterior border of the arm. 



Phymodius sculptus (A. M.-Edw., 1873) A.3, p. L64. 

 Locality : Coral reef, Galle, two small males. 



Chlorodopsis areolata (H. M.-Edw., 1834) A.3, p. 1GG. 



Localities:- Galle, two specimens (adult ? and adult 6); Galle, lagoon, one 

 specimen (young ? ). 



Description : In the adult female, C.l. = 9"50 ; C.b.-f-C.l. = T42 ; Frontal b.-i-C.l. 

 = 0-6G ; Frontal L-j-C.b. = 0"4G. 



The female of this species is figured by Dana under the name Etisodes ccelatus.
