SYNOPSIS OF CLASSIFICATION OF THE LAKE SALMON. 119 



Salmo oquassa or Salmo sebago. The adipose fin, in the male, is situated opposite the 

 anterior margin of the anal [?], whilst in the female it corresponds to the posterior margin 

 of the same fin. 



'The scales are well developed, being somewhat smaller, however, than in Salmo 

 sebago, and considerably larger than in either Salmo oquassa or Salmo erylhrogaster. 

 On the dorsal and ventral regions they are considerably smaller than upon the sides 

 and along the peduncle of the tail. They extend, diminishing in size, over nearly the 

 half of the length of the middle rays of the caudal fin. The lateral line takes an almost 

 straight course along the middle region of the flanks. The following is our approximate 

 formula of the rays of the fins : 



'D 2. 12. A L 9. C 8. I 8. 9. 15. V 1. 9. P 14. 



'There are two anterior rudimentary rays to the dorsal, one or two to the anal, one 

 to the ventrals, eight or ten to the upper lobe of the caudal, to five or six to the inferior 

 lobe. 



'The upper surface of the head and dorsal region are blackish brown; the sides are 

 silvery white, and the belly yellowish. The region above the lateral line is densely spread 

 all over with black irregular spots, some of which are confluent; a few scattered ones 

 may be seen beneath that line upon the middle of the abdomen. Four to six of these 

 spots, well defined, are always observed on the operculum, one of which may occasion- 

 ally reach the preoperculum. A few reddish orange dots, individually situated in the 

 middle of a black spot, are occasionally observed along the middle and upper part of 

 the flanks. Whether these dots are peculiar to the female, or proper to both sexes, I 

 am not prepared to say, from want of sufficient information upon that point. 



'This species was first brought to my notice by M. Townsend Glover, of Fish kill 

 Landing, Dutchess county. New York, who caught it in the upper affluent of Union 

 river in the State of Maine, during the middle of September. I propose the name of 

 Salmo gloverii as a token of gratitude towards an artist whose labors, if promoted, 

 would contribute so much to popularize natural history, and spread its benefits through- 

 out the country.' 



Suckley (1874, p. 143-144) in a paper written in 1861, pronounced Girard's Salmo 

 gloverii the young of Salmo sebago and based his description of the latter species upon 

 three specimens in the Smithsonian collection, one of which was Salmo gloverii. 



After giving detailed descriptions of the three specimens Suckley went on to say: 

 'The young ;S'. sebago may be distinguished from the young of any other salmon and 

 trout on the Atlantic slope, by its strongly-marked black spots and coarse scales. The 

 adult male in the collection was 19 inches long. The young of this fish was described 

 as a distinct species, by Mr. Girard, in 1854, and named the Salmo gloveri. Upon com- 

 paring the types of both, their manifest identity is so apparent, that I have not the least 

 hesitation in making S. gloveri a mere synonym of Salmo sebago, Grd. Three specimens 

 of the species are in the Smithsonian collection — male, female, and young.' 



The three specimens to which reference is made were doubtless those upon which 

 Girard based his descriptions of Salmo sebago and Salmo gloverii.
