146 ROYAL fcfOCIEïY OF CANADA 



St. John Co., a body of water only a few acres in extent with a little 

 C'Utlet into the Bay of Fundy near by, and having no connection with 

 any river system. A year after he found it in a pond near Golden 

 Grove, nine miles from St. John, and there remained, so far as he knows, 

 its only Canadian records until August last, when he collected it from 

 a few small lakes in the valleys of the Grand and Little Cascapedia, and 

 from the Nouvelle lakes, near New Carlisle, P.Q., where it was asso; 

 ciated with P. neogœus. Its distribution, too, recalls that of the latter, 

 for it is reported from Michigan and a few points in the upper part of 

 the Mississippi basin, and recently from Freeport, near Portland, Maine, 

 by W. C. Kendall and Hugh M. Sniitli (Bull. U.S. Fish Commission, 

 1894, pp. 15-21). Erytlirog aster, however, has only 7 dorsal rays, while 

 all our Chrosomi have 8, and in this respect, too, the Maine specimens 

 agree, as well as C. cos, Cope, from the Susquehanna, its next station to 

 the south, which, however, presents a slightly different colour-pattern 

 (Proc. Acad. Nat. Sci. Phil., 1861). 



The Gaspé fish, especially those from the Grand and Little Cas- 

 capedia, are somewhat peculiar. The body is more slender and longer 

 in proportion to the head ; mouth more oblique ; eye large "J3 in 

 snout ; generally seven dark longitudinal lines or bands instead of five, 

 the two extra ones often well defined in life, one on each side of the 

 vertebral line, but seldom reaching the caudal peduncle ; dorsal inser- 

 tion more posterior. Size small, never exceeding 2^ inches. This 

 variety predominates in Harriman's Lake, Grand Cascapedia, and Goose 

 Lake, Little Cascapedia. The Nouvelle (New Carlisle) dace resemble 

 most those found in N-ew Bruns^nck in coloration and proportion of 

 parts. While the slender elongate body recalls eos, the scale formulae 

 82-28 is practically that of erythrogaster. 



To sum up, the Clear Lake and Golden Grove, N.B., Chrosomi are 

 very near to erythrogasler, but the Gasi)é forms exhibit a divergence so 

 marked and constant as to call for recognition ; both are peculiar 

 in the possession of 8 dorsal rays, and to continue to designate them by 

 that name is to ignore the claims of important structural differences. 

 This, however, is a question that can be more satisfactorily dealt with 

 when larger areas have been investigated and more material 

 accumulated. 



Ceratirhtlii/s Plumhcus, Gunther. 



This species was reported first from Loch Lomond, New Brunswick, 

 by the writer in 1893, who subsequently found it at various otlier stations 

 in the province. Being a hardy northern form, its occurrence in Gaspé
