[cox] FRESH WATER FISHES AND BATRACHIA 149 



Rhinichthys cataractœ (Val), Jordan. Long-nosed Dace. 

 Lake Metapedia, P.Q., and generally throughout Xew Brunswick. 

 B. atronasus (Mitch.), Ag. Black-nosed Dace. 



Cascapedia and Bonaventure rivers. Not uncommon in Xew Bruns- 

 wick ; IsTova Scotia, J. M. Jones. 



These two species are with us very closely related, and present at 

 times such an instability of characters as to suggest intergTading. None 

 have the 7-rayed dorsal said to be peculiar to atronasus further south ; 

 that fin has always the 8 rays of cataractœ. The scale formulœ, too, 

 show an approximation ; for cataractœ the average is about 13-63-7 or 

 S ; for atronasus, 11-60-7. The latter is peculiar in having a narrow 

 silvery band bordering the dark lateral band above — a feature nowhere 

 else ascribed to it. 



PEECIDyE. 



Pcrca americana, Schranck. Yellow Perch. 



Though many suitable stations for this species were met with in 

 the peninsula of Gaspé, it was not seen east of the Metapedia, nor was 

 it known to settlers nor Indians to occur in the country. It is, however, 

 quite abundant in Metapedia river and lake, and is generally distributed 

 in New Brunswick and Nova Scotia. It is in all respects typical except 

 in the number of aual fin-rays Mdiich are almost invariably II. 6 instead 

 of II. 7. 



CYPEINODONTID.E. 



Funduhis diaphanus, LeSu. Spring Minnow. 



This, the only fresh-water representative of the family in eastern 

 Canada, so far as the writer knows, is very widely distributed ; and, as 

 is usual with such a species, varies greatly. Its occurrence in New 

 Brunswick was first reported by the writer in Bull. No. XIII. Nat. Hist. 

 Soc. of N.B., pp. 5-7, and Eoy McLean Vanwart and he collected it in 

 Hillsboro river and at Eustico, P.E. Island, in June, 1896. 



Common in the Bonaventure, Grand Pabos, York, and Dartmouth 

 rivers, Gaspé. Abundant in the lower course of the St. John, N.B., 

 and in lakes about the Bay of Fundy. 



The Bonaventure fish, however, are peculiar in the reduced scale 

 formula, narrow and shorter head and snout, scarcely enlarged teeth in 

 outer row, lemon-yellow of inferior parts and fins, and shorter and 

 stouter body.
