ifyxoetoma velata, JosvAjs, Man. Vert., 2d Ed, 1878, 317; Ball. U. S. Nat. Mas,, xii, 



lfc7-, 132. 

 Piychostomus coUapsua, Copjs, Prci. Am. Philoa. Sue. Pbila., 1870, 471. 



Description — Body stont, deep, compressed, the back elevated ; head short, heavy, flat- 

 ■ tish acd broad above, thick through the checks ; eye rather large, midway in head, foni 

 to five in its length ; nuzzle rather prominent, bluntiah, overhanging the very small 

 mouth ; Una very large ; the dorsal long and high, its height five-sixths the length of the 

 head ; pectorals nearly reaching ventrals ; mouth quite small, the lips plicate, the lower 

 lip infolded, j^-shaped when viewed from below, with a distinct median crease, in which 

 the two halves of the lips meet, forming an acute angle; color silvery, smoky above, 

 lower fius red ; head 3| to 4 J ; depth 3 to 4 ; D. 15 to 17 ; scales 6-42-5. Length 1 foot. 



Habitat, Upper Mississippi Valley to Georgia and North Caroliaa, widely distributed, 

 bnt not generally abundaut. 



Diagnosis — This species maybe known by the small and contracted 

 mouth, in connection with the presence of 15 or more dorsal rays. 



Habits. — This species is frequently taken in the Ohio River and its 

 tributaries, but it is not abundant anywhere in the west. In some of 

 the streams of North Carolina, it is the commonest species. It is little 

 valued as food. This seems to be the species called White Nose by Dr. 

 Kirtland, but more than one species is apparently included in his 

 description.

Myxuatoma brevicepa, Jordan, Ball U. S. Nat. Mns , 1877, 9, 50. (Name only.) 



Description — Body compressed, the back somewhat elevated; head short, conic, 

 flattish, formed as in M aureolum; mouth very small, the lips plicate, the lower full and 

 truncate behind ; dorsal fin short and high, falcate, the anterior rays being elevated, 

 and the free border deeply incised, the height of the largest rays being half greater than 

 the base of the fin ; caudal flu with the upper lobe much longer than the lower, falcate, 

 at least in the adult; colors olivaceous, sides silvery with coppery reflections; head 

 5i; depth 3^ ; D. 12 or 13 ; scales 6 4ti-5. Length one foot. 



Habitat, Ohio Valley. 



Diagnosis. — This species is very close to M. aureolum, and may indeed 

 be the male of that species. It may be known from the other Red Horse 

 by the inequality of the lobes of the caudal. 



Hahifs. — I have seen a few specimens of this in the United States 

 Museum, obtained in the Cincinnati market. Prof. Cope's types came 

 from Western Pennsylvania, further than this nothing is known of its 

 habits or distribution.
