30 FISHES OF PENNSYLVANIA. 

38. Moxostoma aureolum (Lez Svevr). 
The Golden Sucker. 
The body of the golden sucker is oblong, the back in front of the dorsal elevated 
and compressed, head short, conic, broad between eyes. The eye is rather large, 
one-fourth length of head, which is contained five times in total length without 
caudal. The depth of the body is contained three and one-half times in this length. 
Caudal peduncle deep, compressed, its least depth equal to one-half length of head. 
Mouth small, the snout somewhat projecting. 
Fins all well developed. The anterior rays of dorsal longest, as long as dorsal 
base ; pectoral and longest anal rays equalling length of head. Caudalforked. Scales 
large, about equal in size all over body and finely striated. D. 15; A. 8; scales, 
6-46-6. Lateral line complete. 
Described from a specimen fifteen and one-half inches long, No. 31,942, United 
States National Museum, obtained in Lake Winnipeg, Manitoba. 
The golden sucker has the additional names of lake mullet, lake red 
horse and golden red horse. It inhabits the great lakes and the region 
northward, also the Ohio valley. It is common in Lake Erie, but not 
in the Ohio. 
This species grows to a length of eighteen inches, and is one of the 
handsomest of the suckers. Prof. Forbes records it from lakes of 
northern Illinois, also abundantly in the central part of that state. Its 
food, according to this author, consists chiefly of mollusks and insects. 
Although freely eaten it has little to recommend it for the table. 
39. Moxostoma crassilabre (Corr). 
The Long-tailed Red Horse. 
The long-tailed red horse has a moderately elongated body, its depth contained 
three and one-fourth to three and one-half times in the total length without caudal. 
The head is short, forming one-fifth or nearly one-fifth of the standard length. The 
snout is pointed, and overhangs the mouth, which is very small. The small eye is 
one-fifth as long as the head. The dorsal is high, the longest rays one and one- 
third to one and one-half times the base of the fin. The margin is concave, making 
the fin faleate. The anal is large, shaped like the dorsal, its tip reaching beyond 
the base of the caudal. The lobes of the caudal are unequal, the upper produced. 
D. 12 to 14; A. 7. Scales, 5-44-5. The dorsal and caudal fins are bright red, the 
sides silvery tinged with dusky above, some dark spots at the bases of the scales 
and the lower fins white. 
The long-tailed red horse is an inhabitant of the Ohio valley, and 
ranges southward to North Carolina. It is described as having the 
form of a white-fish, the body deep, the head small and with a sharply 
conic and projecting snout; the lobes of the tail are unequal, the upper 
one being much the longer. This is a handsome species, the sides sil- 
very with copper reflections. The dorsal and caudal fins bright are red. 
Prof. Cope found it in western Pennsylvania. Its habits are doubtless 
similar to those of other species of the genus, but there is nothing on 
record about this subject, so far as we know.
