NOTES ON SOME JAPANESE FISHES. 



Tetronarcine tokionia. 



About rr natural size. 



Color in formalin brown ; no 

 markings ; whitish beneath, brown 

 narrowly along the margins. 



According to Dr. Jordan and 

 EvERMANN*^ Tetronarcine occidentalis 

 occurs on the Atlantic coast of the 

 United States, North America, from 

 Cape Cod to Cuba, while Tetronar- 

 cine californiea is found on the 

 coast of California, on sandy shores, 

 especially about 8an Francisco and 

 Santa Cruz. The differences^'^ between 

 these species are as follows : — 



Color nearly uniformly black Avith obscure darker spots, first dorsal over 

 the middle of rentrais, caudal slightly emarginate occidentalis. 



Color very dark brown, usually spotted with black, first dorsal inserted 

 behind middle of rentrais, half of the former opposite the latter, caudal 

 truncate or very slightly rounded californiea. 



In Tetronarcine tokionis, less than half of base of first 

 dorsal is opposite to ventrals, caudal emarginate, and back brown 

 with no markings. 



Dr. Günther''^ says that Narcine timlei occurs in Japan, but 

 I have not as yet come across a specimen of it in this country, 

 and I agree with Jordan and Fowler'^^ that there is no evidence 

 that it had ever been taken in Japan.
