Description.—T he Short-nosed Gar is very similar to the preceding species in size, color, 
dentition, etc. The body is, however, rather deeper, and the snout is notably shorter, 
being only about as long as the rest of the head. Different specimens vary considerably 
in the length of the snout, and some specimens are very pale, while others are dusky or 
more or less distinctly spotted. Length, 2 to 5 feet. 
Habitat, Great Lakes to Florida and Texas, abundant is most large bodies of water, 
most common southward. 
Diagnosis —From the Alligator Gar, this species may be known by the 
presence of a single row of teeth on each side of the jaw. From the 
Long-nosed Gar, the shortness of its snout will distinguish it. 
Hvbits—This species is not common anywhere in Ohio, and it is more 
often found in the Ohio River than in lake Erie. In habits, food, etc., 
the two fishes are so far as known precisely identical. 
This species like the preceding, has been frequently made the type of 
new species, but being less common in collections, it has suffered some- 
what less. : 
GENUS 7. LITHOLEPIS. Rafinesque. 
Litholepis, RAFINESQUE, American Monthly Magazine, ili, 1818, 447. 
Atractosteus, RAFINESQUE, Ichthyologia Ohiensis, 1820, 72. 
Type, Litholepis adamantinus, RAFINESQUE, 1818; Lepisosteus ferox, RAFINESQUE, 1820, 
= Tepisosteus spatula, LACEPEDE, 1803. 
Etymology, lithos, stone ; lepis, scale. 
Gar Pikes with jaws comparatively short and broad, the snout rather wide, about as 
long as the rest of the head, and the large teeth of the jaws in two rows on each side. 
Species reaching a very large size. The name Atractosteus has been most frequently em- 
ployed for this genus, but as will be seen by the above synonymy, the preferable name 
Litholepis is two years the older. But one species is known from the United States, but 
two others, perhaps identical with ours, are described from tropical America.
