168 FISHES—ACIPENSERIDZAR. 
in the evening, leaping from the surface, throwing their bulky forms en- 
tirely out of the water. 
In regard to the game qualities of this species, Mr. eeMeae says 
(Sportsman’s Gazetteer, 4th Ed., 389) : | 
‘The long projecting sucker mouth situated almost under the center of the head 
will sometimes suck in from the bottom the anglers baited hock, in which case, one 
may as well try to snub an old log. It is possible, however, to coax him to move occa- 
sionly, and then you may, or you may not, succeed in bringing him togaff.” * * ‘As 
a game fish, the sturgeon is not a success.” 
5. ACIPENSER MACULOSUS LeSueur. 
Ohie River Sturgeon. 
Acipenser maculosus, LESUHUR, Trans. Am. Philos. Soc., New Series, i, 393.—GUNTHER, 
Cat. Fishes, Brit. Mus., viii, 339, and of authors generally. 
Description —This species is very similar to the preceding, and all the specimens 
which the writer bas had the opportunity to examine, seem to him to be the 
young of the preceding. The snout is more pointed than in the Lake Sturgeon; the 
skin rougher; the scutes are more strongly keeled and their spinous peints are placed . 
much behind the middle of the shield, and are directed backward more than is the case 
in the preceding. As observed long ago by Dr. Kirtland (Bost. Journ. Nat. Hist., iv, 
1812, p. 304.), ‘These characters are not, however, permanent, and therefore are not to 
be relied upon. If the maculesus of LeSueur, be not the young of the others, their young 
have never been discovered.” 
Habitat, Ohio and Mississippi Rivers. 
Habits.—The habits of this fish are essentially similar to those of the 
preceding, and a more careful comparison of the two must be made before 
any important specific differences (if such exist) be pointed out.
