tions or blotches, and sometimes both, extending on the head. 

 The fins are usually pale; occasionally the dorsal and anal 

 have several faint, band-like, brown markings, and the tail fin 

 is inconspicuously banded. 



Hybrids one year old, between female saibling and male 

 Salmo fario, are four inches long ; between female fario and 

 male saibling they are 3 7-10 to 434 inches. Two-year-olds 

 vary from 6^ inches to 8 2-5 inches. Three-year-olds, pro- 

 duced by fertilizing saibling eggs with the milt of Salmo faiio, 

 measure 9^4^ inches ; the opposite cross of the same age varies 

 from 10 inches to 10^ inches. Four-year-olds, crossed 

 between female saibling and vci?i\Q fario vary from 1 1 1^^ to 

 11^ inches ; those crossed the other way are 11 inches long. 

 Five-year-old hybrids between male saibling and female Salmo 

 fario, range from 13 inches to 14 inches in length- Six-year- 

 olds, between male saibling and female fario, measure from 

 17 inches to 19^ inches; those between va-a^^ fario and 

 female saibling are from 17 to 18 inches long. 



None of the specimens examined by me show any develop- 

 ment of the reproductive organs, and it is probable that this 

 hybrid, although a large and beautiful animal, is uniformly 

 sterile. 



Dr. Kingsbury. — I would ask if the flesh of hybrids is 

 better than that of either parent t 



Dr. Bean replied that the specimens with which he was 

 familiar are alcoholic, but, Mr. Hansen, of Norway, recom- 

 mends a cross between a saibling and the brown trout as an 

 excellent fish for the table. 



Mr. Ford could answer the question. He had eaten a fish 

 which was a cross between a lake and a brook trout, and, 

 while it was not quite as good as a brook trout, it was a good 

 table fish. 



Mr Powell thought that such hybrids would revert to 

 brook trout, if placed in trout streams. 



Dr. Hudson considered that the cross between lake and 

 brook trout is the one most able to resist adverse influences,
