distinctive characters of this trout, and subsequently puhlishcd 

 the results of his investigations in the Proceedings of the Boston 

 Society of Natural History (Vol. IV, p. 262,) of which the follow- 

 ing is a copy : 



" He had often been told by Anglers that the trouts of those 

 waters (upper lakes of the Androscoggin) Salmo eryihrogasler and 

 S.fonlinalis are subject to considerable variations, making it prob- 

 able, in their opinion, that there were more than two species. 



" Visiting the locality he had an opportunity of seeing and com- 

 paring large numbers of individuals. He satisfied himself that all 

 the varieties spoken of are mere varieties of color, and all referable 

 to either Salmo fontinalis or S. eryihrogasler. He was told however, 

 that about the 10th of October another trout, smaller in size than 

 the common brook trout, and inhabiting the deep waters of Moosil- 

 lamaguntic lake, would make its appearance near shore and as- 

 cend in large numbers the eastern inlet called Kennabago. This 

 actually took place, and the trout on examination proving to be 

 very different from Salmo fontinalis and the other species of Salmo, 

 he named it Salmo oquassa* Girard, and gives the following 



"Specific Description of it. It is from eight to ten inches in total 

 length. The body is subfusiform, slender, and the most graceful 

 of the trout family. The head is proportionally small, conical, 

 coregonoid in shape. 



" The mouth is smaller than in Salmo fontinalis. Differences are 

 likewise observed in the structure of the opercular apparatus. The 

 fins have the same relative position as in the brook trout, but are 

 proportionally more developed, with the exception of the adipose 

 which is considerably smaller. Their shape is alike except that of 

 the caudal, the crescentic margin of which is undulated instead of 

 being rectilinear. The scales are somewhat larger, although they 

 present the same general appearance as those of the brook troi^t. 



" The lateral line is similar in both of these species. A bluish 

 tint extends all along the back from the head to the tail, so tliat 



*Thc Dr. gave it this name undoubtedly from tlio Indian name {oquassa) of the 

 lake in which he found it — now Rangcly lal{C. I object to his mode of spelling it. 

 Matalluck, an Indian of the St. Francis, who for a long time lived 0!i those lakes, 

 and who used to be considered the guardian genius of that locality used to pronounce 

 the name of this lake, Argwas-suc, making a slight pause between the second and 

 third Bylhiblcfl.
