Lepidosteus osseus Giinther, Cat., vin, 330, 1870; North America. 



Lepisosteus osseus Jordan & Evermann, Bull. 47, U.S. Nat. Mus., 

 1896, 109: Jordan & Snyder, Bull. U. S. Fish Comm., 1900,

Great Lakes to the Carolinas and Mexico as far south as Tam- 

 pico. (San Juan; Valles; Forlon.) 



Head 3; depth 12; D. 8; A. 9; scales about 62. Body elongate, 

 cylindrical; jaws long and slender, beak-like; snout more than twice 

 length of rest of head, its least width 15 to 20 in its length; 

 large teeth of the upper jaw in a single row on each side; ventral 

 fins with 6 rays. 



Color olivaceous, pale, somewhat silvery below; vertical fins and 

 posterior part of the body with round black spots, which are more 

 distinct in the young; very young with a black lateral band. Length 

 about 3 feet. 



The most southern record of this species is Valles, in the 

 Rio Panuco Basin. I saw quite a number in a deep sluggish creek 

 at Forlon, but was unable to capture any of them. This species 

 seldom exceeds a length of 3 feet, and except on the Arkansas River, 

 I have never seen it used for food. It is easily distinguished from 

 the other members of the family by its exceedingly long, narrow, 

 beak-like jaws. 



Subgenus Oylindrosteus Rafinesque. 



Lepidosteus platystomus Rafinesque. SHORT-NOSED GARPIKE. 



Lepisosteus platostomus Rafinesque, Ichth. Ohiensis, 72, 1820; Ohio River. 



Lepidosteus platysiomus Gunther, Cat., vin, 329, 1870: Jordan & Evjrmann, 

 Bull. 47, U.S. Nat. Mus., 1896, no. 



Mississippi Valley south to the Rio Pecos in Texas, ranging as far east as 

 Florida. 



Head 3^; depth 8; D. 8; A. 8; scales about 56. Body elongate, cylindrical; 

 jaws broad, beak-like; snout usually about one-third longer than rest of 

 head, its least width 5 to 6 in its length; large teeth of upper jaw in a single 

 row on each side. 



Color similar to the preceding, but usually darker. Length 2 or 3 feet. 



This species probably occurs in northeastern Mexico. 



Subgenus Atractosteus Rafinesque.
