be correct, but Richardson's description is so vague that we can only bo sure that his fish was 

 some one of the alpinus set, with red spots and a red belly, perhaps a nitidus or slagnalis. 



The Sunapee chair is certainly not a hybrid between the saibling and any other species, 

 European or American. The hybrid alpinus X/an'o, examined by me, has the scales adherent as in 

 alpinus, but almost as large (135 series) as in Salmo fario. Its gill rakers, 6 + 11 or 12, are stif- 

 fish and nearly straight; there are a few teeth on the shaft of the vomer (fario has many, the 

 species of Salvelinns none at all) and the color is very eccentric. The body is dark and is clouded 

 all over with sharply defined yellowish reticulations, which extend on the head and fins. Its 

 coloration somewhat resembles that of a pike. It has neither the red spots of alpinus nor the 

 black spots of fario. 



In this connection we may briefly notice the other nominal species of charr described from 

 British America and Greenland. Salvelinus arcturus seems to be a form or variety of S. alpinus as 

 already noticed. The same is true of Salvelinus nitidus and of Salvelinus stagnalis. Salvelinus alipes 

 is the same as stagnalis, and rossi probably identical with nitidus, as is also Salvelinus hearnii. 

 Salvelinus hoodi was based on a mixed lot of Salvelinus fontinalis and S. namaycush. Salvelinus hud- 

 sonicus, canadensis, and immaculatut are fontinalis, the latter name given to sea-run specimens. 

 But for all we know the alpinus may run out to sea as well and become immaculalus, too. Salve- 

 linus naresi, from the Arctic regions, seems to be the same as oquassa. If these views be correct, 

 we have in America five species of charr, each highly variable and running into many local 

 varieties. 



As for the Sunapee charr itself, we may say that it seems to be distinguished from all the 

 other forms of charr by its gill rakers. It is probably not a distinct species, and it is probably 

 native to the waters in which it is now found, and not an importation from Europe. Should it 

 appear, however, that the saibling in that part of Germany from which specimens have been 

 brought to America have gill rakers like those of the Sninapee trout, this opinion would be 

 reconsidered. Other lakes of Maine, Quebec, Labrador, and Boothia must be explored before 

 these questions can be definitely settled. 



It is interesting to notice that just as the right of the saibling to be regarded as a native 

 American has been questioned in this country, so has its citizenship in England been also denied. 



Dr. Day tells us that in olden times the people were 'taught that three sons of the church 

 introduced these fishes into Wales from Rome, and placed two in each of the lakes of Llan- 

 berries, Llynumber, and Trevennyn.' Perhaps we are justified in supposing that by the same 

 persons and at the same time two were placed in Suuapee Lake, two in Dan Hole Pond, and two 

 in the sea nt Disco."

V86. SALVELINUS OQUASSA (Girard). 

 (OQUASSA TROUT; BLUEBACK. TROUT; QUASKY.) 



Head 5; depth 5; eye large, 3i in head. D. 10; A. 9; scales 230; gill 

 rakers about 6 -f- 11. Body elongate, considerably compressed, less ele- 

 vated than in the other species of this genus, the dorsal outline regularly 

 but not strongly curved. Head quite small, smaller than in any other of 

 our trout, its upper surface flattish ; mouth quite small, the maxillary short 

 and moderately broad, scarcely extending to the posterior margin of eye. 

 Jaws about equal. Scales small, those along the lateral line somewhat 

 enlarged. Pectoral and ventral fins not elongate; caudal fin well forked, 

 more so than in the other species ; preopercle as in S. fontinalis, but the 

 lower limb more developed ; opercles without concentric striae. Colora- 

 tion dark blue, the red spots small and round, much smaller than the pupil, 

 usually confined to the sides of the body ; sides with traces of dark bars ; 

 lower fins variegated, as in S. fontinalis. Length 12 inches. Smallest and
