found, and not an importation ffom Europe.' "Should it 



appear," lie continues, "that tlie saibling in that part of 



Germany from which specimens have been brought to America, 



have gill-rakers like those of the Sunapee trout, this opinion 



would be reconsidered." Professor Garman has dis^josed of 



the gill-rake argument, but, as far as I know, Professor Jordan 



has not further expressed himself in regard to the Sunapee 



form ; although in a recent article on the salmon and trout of 



the Pacific coast he states, that in the lakes of Greenland and 



the Eastern part of British America the European charr is as 



abundant as it is in Europe — a fact which has only lately been 



made manifest." Mr. J. G. A. Creighton, of Ottawa, Canada, 



writes under date of Feb 16, 1893: "From the height and 



character of Sunapee Lake, it is not at all improbable that an 



Arctic variety may have survived there, which has perished, or 



been transformed, elsewhere south of 55° or 60° N. Lat. Arctic 



species must have been common to all our waters in the Glacial 



Period." Professor Garman writes me, of November 17, 1892, 



that " no good evidence has been advanced of the existence of 



this species on this continent, previous to 1884." It is a matter 



of record, however, that 60,000 German saibling eggs, the gift 



of the Deutsche Fischerei-Verein, wex'e sent to New Hampshire 



in January, 1881 . It is further to be taken into consideration that 



the writer of this paper had in his possession, at Sunapee Lake, 



in the summer of 1882, a four-pound specimen of the saibling 



in question — which could not have developed from fry hatched 



the preceding year! No saibling have ever been sent to INIaine 



by the United States Fish Commission ; and, as has been shown, 



it is impossible that the fish in Flood's Pond can be descendants 



of the New Hampshire charr. The theory that there was nothing 



in recent years to prevent the Salvelinus a//n'/ii(*- of Sunapee Lake 



from descending the Connecticut River to Long Island Sound, 



and thence making its way into streams and connecting lakes 



from the shores of Connecticut to those of Greenland, ma}- be 



disposed of in a single word — Dams. 



The Sunapee charr is undoubtedly a representative of the 

 European form ; but reasons have been given why it is believed 

 to be a native of this continent. It differs no more extensively 

 from the several European varieties than they do among them- 

 selves. Von dem Borne, Professors Benecke and Dalmer, 

 Wittmack, of Berlin, all speak of important differences in form, 

 size and color, according to age, sex, season and habitat. All 

 authorities allude to the solid sea-green or dark-blue of the 

 back, ttie 3'^ellowish sides, and the red or orange belly. Benecke 

 and Dalmar refer picturesquely to the half-moon tail. As to
