15 rows of scales in front of dorsal. Dorsal low, its longest ray f 

 head. Pale olivaceous; sides usually pale; usually a darker dorsal band 

 and a small dark blotch before dorsal, sometimes a plumbeous lateral 

 stripe but no caudal spot ; rms all plain. Length 2 to 2i inches. Ohio 

 and Michigan to Tennessee, Dakota, and Kansas, thence southwestward to 

 Texas; generally abundant in small streams; an insignificant little fish. 

 Very variable and running into several varieties, the typical blennius 

 (= deliciosus = missuriensis), Missouri to Texas, having the scales usually 

 32 to 35; var. stramineus, from Ohio to Iowa and southward with scales 

 34 to 38, usually 36. We follow Dr. Meek in identifying Girard's Albur- 

 nops blennius with this species, (blennius, blenny , from the convex profile. )

Head 3-J; depth 4; snout 3| in head, as long as eye. D. 8; A. 7; scales 

 4-33-2 ; teeth 4-4, hooked, with some grinding surface. Al.Ued to Notropis 

 blennius, but quite different in form, resembling a young Moxostoma. Body 

 robust, the tail long and thick, the back elevated, the sides little com- 

 pressed. Head long, broad and flattish above. Mouth rather large, nearly 

 horizontal, the maxillary reaching past front of pupil. Scales very large, 

 those on back not reduced, 14 before dorsal. Dorsal inserted nearly over

f" While these pages were setting in type, I have received another pretty species of this 

 interesting genus, through the attention of Dr. I. H. Rauch, from Burlington, Iowa. The large 

 number of specimens obtained enables me to make some additions to the characteristics of the 

 genus : 



The mouth is protractile downwards, after the fashion of Catostomus, so much so that had 

 I not ample opportunity to examine young Catostomi, and to study the changes they undergo 

 with age, I might have supposed my Hybopsis to be the young of some species of that genus. 

 Moreover the lips are not swollen nor thickened. The pharyngeal teeth differ also greatly trom 

 those of Catostomi, there being only 4 or 5 compressed and hooked ones in each main row, and 

 1 or 2 in a second row. 



This new species differs from that of riuntsville by its smaller size, its more pointed snout, 

 and the peculiar coloration. A deep black narrow band extends from the neck to the base of the 

 caudal along the whole back, dividing in advance of the dorsal to encircle that fin, and uniting 

 again behind it upon the middle line. General color olive, silvery upon the sides, the dorsal 

 and caudal faintly tinged with rose color and a deeper rose-colored spot upon the base of the 

 first ray of the dorsal. I shall call this species H. dorsalis, Ag." Agassiz.
