316 ME. F. DAT OTSr THE RELA-TIONSHIP OP THE 



species of Arius in the seas and estuaries. Jerdon admitted 

 none among his list of "the Freshwater Fishes of Southern India " 

 (Madras Journ. Lit. & Sci. xv. 1849, pp. 139, 302). As far as 

 my personal investigations in the East have gone, if the Ariinse 

 elsewhere have the same habit as along the coast of India, these 

 40 species should be erased from the freshwater fish-fauna. 



" Bagariika, 20 species ; " 16 are in the Catalogue. 



" EHiNOGLAJsriNA (Africa), 1 species," as in Catalogue. 



Hypostomatota (South America), 5 species." — Five in the 

 Catalogue ; but, as I long since pointed out, genus UretMstes, V., 

 p. 263, is identical with Hara, p. 189 ; but this form possibly is 

 not one of the five. 



" CTPEiNODONTrD^. — SaplocMlus, 4 species." 



ScoMBEESOCiD^. — Omitted from the Indian freshwater fish- 

 fauna by Dr. Griinther. Belone cancila : the habitat given in the 

 ' Catalogue of the Fishes of the British Museum ' (vi. p. 253) is 

 *' Indian Ocean ; " I gave it as " fresh waters of Sind, India, and 

 Ceylon, and throughout Burma." Hamilton Buchanan observes 

 that it " is a very common fish in the ponds and smaller rivers of 

 the G-angetic provinces " (G-angetic Fishes, p. 214), Sykes, 

 'Fishes of the Dukhun,' p. 367, terms it "a freshwater fish" 

 found in the Mota Mola river at Poona. Jerdon, ' Freshwater 

 Fishes of Southern India ' (p. 345) states that " this fish is found 

 in most of the rivers of the west coast up to the base of the 

 mountains." 



Ctpeinid^. — Of these as given in the list in the ' Introduction ' 

 (if we omit the majority of such as I have discovered in India) we 

 have a fair compilation. Osteoglossid^, WoTOPTEEiDiE, and 

 Stmbeanchid^ call for no observations. 



If we analyze Dr. Griinther's list with the foregoing remarks, 

 we obtain the following results : — 



Present in Indian and African regions : — 1 Labyrinthici, 2 

 Ophiocephalidge, 3 Mastacembelidse, 4 Chromides, 5 Clariina, 

 6 Silurina, 7 Bagrina, 8 Ehinoglanina, 9 Cypriaodontidse, 10 

 Cyprinina; 11 Easborina, 12 Danionina, 13 Abramidina, 14 Osteo-^ 

 glossidsB, 15 Notopteridge. The groups Percina, genus Lates, and 

 Ariina must be erased, as not belonging to freshwater fauna. 



Eestricted to India : — 1 Nandina, 2 Luciocephalidse, 3 Cha- 

 cina, 4 Bagariina, 5 Hypostomatina, 6 Semiplotina, 7 Homalo- 

 pterina, 8 Cobitidina, and 9|Symbranchidse.
