FISHES OF NEW YORK 229 



:fins dusky; that of the pectorals tinged with lemon yellow; ven- 

 trals dusky at the tip; anal pale; caudal pale except a narrow 

 •dusky portion of the middle rays; eyes pearly with golden iri- 

 descence. The maxilla reaches about to front of eye. The 

 -adipose dorsal extends straight backward, and its base is cov- 

 <ired with a sheath of small scales nr of an inch wide. The 

 ^ill rakers are 9 + 17, the longest f of an inch. Very small teeth 

 are present on the tongue. The eggs are minute. 



In a male example, 17J inches long, received Nov. 16, 1895, 

 irom Upper Saranac lake and nearly spent, no tubercles could 

 l)e seen on the scales; but several of the males from Oanan- 

 <iaigua lake had them well developed. There is a great differ- 

 •ence in the development of the lingual teeth, some of our indi- 

 Tiduals showing only a trace of them, and it seems as if there 

 may be some relation between their condition and the sexual 

 maturity of the fish. For example, in a male 14 inches long, 

 «ent from the fourth lake of the Fulton Chain Nov. 9, 1897, the 

 lingual teeth were present in a large patch; in three males, only 

 ^ little smaller but sexually immature, from Saranac lake Nov. 

 11, 1897, the teeth on the tongue could be perceived by the 

 touch only. The following measurements, in inches, and addi- 

 tional notes, were made from the fresh fish.
