not reaching front of eye, its length 2| in head. Barbel conspicuous, 

 as long as eye. A raised rim above nostrils on each side, the space be- 

 tween them concave. Snout long, 2f in head. Eye very small, placed 

 high, 4 J in head. Interorbital space flatfish, about as wide as eye. 



Fins all very high,^the pectorals somewhat filamentous, reaching past 

 front of dorsal, a little longer than head. Dorsal elevated in front, its 

 longest rays slightly longer than head, its insertion nearly over that of 

 the long ventrals. Caudal long, very deeply forked, its lobes 3^ in body. 



This species is closely related to E. hyostomus, H, cestivalis {=st€rletus), 

 H. montanus, H. lahrostts, and R. zanemus. These species form a group 

 by themselves (perhaps worthy of generic distinction from Hybopsis), 

 characterized by the great development of the maxillary barbel, and 

 by their small size and feeble structure. All seem to abound chiefly in 

 flowing water, especially in river channels.

E.— Ta6o Creek. 



Tabo Creek, about 6 miles east of Lexington, Missouri, is a small trib- 

 utary of the Missouri Eiver, rather swift and muddy. At the time of 

 our visit its waters had risen on account of heavy rains, so that we 

 got biit few fishes. In the U. S. National Museum is a specimen (36758) 

 of Enneacanihus eriarchus taken in this stream by Dr. P. E. Hoy.

F. — La Mhie River. 



Two tributaries of La Mine River were examined — Blackwater Creek 

 at Brownsville, Saline County, Missouri, and Flat Creek, near Sedalia. 

 The former is muddy and swift, and at the time was swollen by fresh-
