[cox] FRESH WATER FISHES AND BATRACHIA 151 



classed as a Coitus, for the ventral fin has one concealed spine and four 

 soft rays, while Uranidea has but three of the latter. Its varieties are 

 as numerous as its localities, but the following was the most conspicuous 

 met with : — 



U. richardsoni, Ag. var. — A peculiar type from Bonaventure Eiver, 

 distinguished by its tadpole shape, wide separation of the dorsals, and 

 uniform black colour. 



SALMONID^. 



Coregonus labradoricus, Eich.? White Fish. 



A Coregonus occurs sparingly in the Grand Cascapedia, of which 

 specimens could not be obtained ; but, judging from descriptions given 

 by persons familiar with it, the writer thinks it is the above species. It 

 seems confined to this river, for guides, settlers and Indians had never 

 met with it elsewhere on the peninsula. Not uncommon in the St. John 

 Eiver, N.B., and in many of its tributary streams and lakes, especially 

 above Grand Falls, where it is associated with C. quadrilateralis, Eich. ; 

 found also in the Eestigouche and Metapedia. Our form at least is 

 very closely allied to C. alhus, LeSu., of the Great Lakes and north- 

 westward, of which it is probably a modified mountain or river form, as 

 suggested by the character of the main points of difference — a slight 

 increase in the scale formula and number of dorsal ray supports (being 

 frequently 12 instead of 11), and the more elongate body. 



Among the fresh-water fishes of New Brunswick none are more 

 common nor characteristic of its streams, rivers, and lakes than Semotilis 

 huUaris, Eaf., Silver or Eiver Chub ; Lepomis gibhosus, L., Sun-fish, 

 Pond-fish ; Amiurus catus, Gill, Horned Pout, Cat-fish ; and Lota 

 maculosa, Cuv. & Val., Burbot, Cusk ; all of which are absent from the 

 Gaspé rivers and lakes, and only one, L. maculosa, is known to the writer 

 to occur in the Eestigouche. They are, however, in the main peculiar 

 to lakes, ponds, lowland streams, and the lower courses of rivers, and 

 hence, possessing little power of disper^l, their transmission from one 

 river system to another, especially in a mountainous country, is nigh 

 impossible. 



EEPTILIA OF GASPE. 



Though no part of the primary object of the investigation, it was 

 thought desirable to examine the reptilian life of the peninsula, as far 

 as time permitted, and append a list thereof to this report. Compared 

 with that of New Brunswick, there is a dearth of both species and 

 individuals.
