 a shorter snout and a smaller eye than the typical a t h e r - 

 i n o i d e s and has received the specific name d i.n e m u s ; but 

 the differences are not supposed to be constant. The emerald 

 minnow reaches a length of 6 inches; it is gregarious like other 

 minnows; and its golden lateral stripe on a clear green ground 

 makes it a handsome species. 



Dr Meek found one example near Ithaca, in Six Mile creek, 

 below the falls. A few^ specimens w^ere also found in a small 

 stream near Montezuma dry dock, in company with N. 

 1 y t h r u r u s . Evermann and Bean caught a single example 

 in Scioto creek, Coopersville, July 19, 1894; also three specimens 

 in the St Lawrence river, 3 miles below Ogdensburg July 17, 

 1894. At Cape Vincent June 21, 1894, the U. S. Fish Commission 

 collectors took 29 specimens, and at Grenadier island, June 27, 

 they obtained 14 individuals. Livingston Stone also collected 

 the species at Cape Vincent Aug. 9, 1898, and presented speci- 

 mens to the State Museum.

The rosy-faced minnow has the body moderately long and thin, 

 with a short and deep caudal peduncle. The greatest depth of 

 the body equals one fourth, and the least depth of the peduncle, 

 one eighth of the total length to base of caudal. The head is 

 moderate in size; its width one half of its length, which is one 

 fourth of the total to base of caudal. The snout is pointed and 

 shorter than the eye, which is one fourth to two sevenths as 

 long as the head and equal to the distance between the eyes. 

 The mouth is oblique, and the lower jaw projects slightly; ttie
