Body elongated and compressed, fins large, anal fin ivith ii or 

 12 rays, a distinct black spot at base of first rays of dorsal, scales 

 small, 30 before dorsal fin, lateral line decurved ; females pale, 

 males steel blue, belly and lower fins fine brick-red in the Spring. 

 Length 2j^ inches. 



Not very common ; found in Black River and in "\'ermillion 

 River near Kipton. 



Scales larger and loosely set. {The species of this group are extremely closely re- 

 lated, and in some cases scarcely distinguishable. — Jordan.) 



36. Notropis dilectus (Girard). Rosy-faced Minnow. 



[Jord: Man. 128. O. St. Surv. 69.] 



Slender and graceful, of a translucent olive-green with broad 

 silvery bands on the sides ; head larger than in related species ; dor- 

 sal fin inserted behind ventrals ; length 3 inches. My specimens 

 show ig to 20 rows of scales before dorsal, instead of the " about 

 15 " of the manual. 



Common in the lake and lower parts of all streams entering it. 

 Found accompanying the next species. 



37- Notropis atherinoides (Rafinesque). Emerald 

 Minnow. 



[Jord. Man. 129. O. St. Surv. 70.] 



Very much like the preceding but with shorter, blunter head 

 and of much larger size, reaching a length of 6 inches ; very 

 abundant at times, so that the schools darken the water. The fisher- 

 men say that their coming into the rivers is a "sure sign" of a 

 storm. 



38. Notropis arg-e (Cope). Silvery Minnow, 



[Jord. Man. 130. O. St. Surv. 70.] 

 Like the preceding species, but with a comparativel}' larger 

 head, much larger eye and slender form; length 3 inches. 



Found in company with atherinoides, but not nearly so common. 



39. Ericyiiiba buceata (Cope). Silver-jawed Minnow. 



[Jord. Man. 132. O. St. Surv. 76.] 



Body spindle-shaped, rather long, head long with broad muz- 

 zle. Bones of the jaws with J or 8 mucus chambers appearing as 

 silvery bars in four rows across lower half of the head. Length 5 

 inches. 



Taken once in Black River, near Elyria.
