As regards the Arctic char, of which there are a number of specimens 
in the collection, probably when all the reputed varieties are better known, 
it may be found that all are referable to one and the same species, viz.: 
Salvelinus alpinus. Nevertheless, if such be the case, it has been recorded 
under a number of trinomial distinctions, such as : 
Salvelinus alpinus alipes Richardson 
, “ stagnalis Fabricius 
“ arcturus Gunther 
I regard these to be, at most, only local variations, indigenous to the 
cold Arctic waters, of the typical European Salvelinus alpinus, and have, 
therefore, provisionally placed it binominally in the list. There is much 
confusion in the reports of these alleged varieties, some of the records of 
which are very old or very locally reported. Another alleged species 
or subspecies, recorded presumably only from Discovery bay and Cum- 
berland gulf, is Salvelinus oquassa naresi Gunther, which may not be 
separable from the typical S. oquassa, which itself, in so far as I know, has 
only been recorded from Rangeley lake in the state of Maine, and it may 
even be questionable whether or not >8. alpinus and S. oquassa are them- 
selves separable as species. 
It is quite feasible to suppose that fishes with a more or less circum- 
polar distribution might extend as varieties to the temperate zone either 
of Europe or America, so that there may be no real justification in separat- 
ing them as distinct species, and S. alpinus and S. oquassa may be a case 
in point; but until, for comparison, there is access to a large and well- 
preserved number of specimens, the question as to specific or subspecific 
rank of certain little known fishes of the Arctics must be held in abeyance. 
But, with the proviso, in substance, my real hesitancy as to identifica- 
tion lies with the sculpins, and the indecision is more in regard to species 
than to genera. There are all of fifty different kinds of sculpins considered 
to be indigenous to the waters of the Dominion, some of which are not 
well demarked from others. In the collection there are several specimens, 
belonging to at least two species, but it would require a series of specimens 
with the colours well preserved and other features pronounced in order to 
determine them with any degree of certainty. 
Insects from Baffin Island 
By J. H. McDunnough 
The insects collected by Mr. J. D. Soper in Baffin island in the summers 
of 1925 and 1926, and submitted to me for incorporation in the Canadian 
National collection, proved most interesting and of high scientific value. 
The best collection was made around Nettilling lake in 1925; the specimens 
collected in 1926 were taken in the vicinity of cape Dorset and were fewer 
in number. Although the actual number of species represented is not 
very great, it must be remembered that the insect fauna of these far north- 
ern regions is very limited and it is safe to conclude that Mr. Soper’s 
material contained a fairly complete representation of the insects of Baffin 
island. The following is a complete list of the species represented; in a 
few instances the identifications have not been completed and it is quite 
possible that several new species may be included.
