NOTES ON BATOID FISHES. 

 BY HENRY W. FOWLER. 



The ray-like fishes contained in the collection of the Academy of 

 Natural Sciences of Philadelphia are listed in this paper. 



1. Some Preoccupied Names. 



In looking over the literature on this subject a number of names 

 were found to be preoccupied, which are not represented in our col- 

 lection by specimens, and for them I have substituted the following: 



Raja montagui nom. sp. now For Raia maculata Montagu, Mem. 

 Wern. Soc, II, 1811-16, p. 426, preoccupied by Raja maculata Shaw, 

 Gen. Zool., VII, 1803, p. 16, which is identical with Raja torpedo 

 Linnaeus. 



Raja brachyurops nom. sp. nov. For Raja brachyura Gunther, 

 Rep. Challenger, Zool., I, 1880, p. 20, PL 6, preoccupied by Raia 

 brachyura Lafont, Act. Soc. Linn. Bordeaux, XXVIII, 1871, p. 503, 



PI. 28. 



Raja bon.e-speiexsis nom. sp. nov. For Raja capensis Miiller 

 and Henle, Syst. Besch. Plag., 1838, p. 151, preoccupied by Raja 

 capensis Gmelin, Syst. Nat. Linn., 1788, p. 1512, which is identical 

 with Narke Kaup. 



Raja steindachxeri nom. sp. nov. For Raja chilensis Stein- 

 dachner, Zool. Jahrb. Suppl.. IV, 1898, p. 332, preoccupied by Raia 

 chilensis Guichenot, Gay's Hist, Chile, II, 1848, p. 367. This species 

 appears close to Raja lima Poeppig. 



Raja agassizi ribeiroi, nom. sub. sp. nov. For Raja agassizi var. 

 picta Ribeiro, A Lavoura, Bol. Soc. Agric. Rio Janeiro, 1904, 

 p. 19, preoccupied by Raja picta Lacepede, Hist. Nat. Poiss., IV 



1803, p. 676. 



Discotrygon nom. gen. nov. Type Discobatis marginipinnis 

 Maclay and Macleay. For Discobatis Maclay and Macleay, Proc. 

 Linn. Soc. N. S. Wales, X, 1885, p. 676, type Discobatis marginipinnis 

 Maclay and Macleay, preoccupied by Garman, Proc. U. S. Nat. Mus.,
