taken was 28 inches long and weighed 9 pounds. It is probably this species 
that resorts in large numbers to certain streams about Cumberland sound, 
to Padle river in Merchants bay, and Salmon river at Ponds inlet. 
NOTES ON A COLLECTION OF FISH FROM BAFFIN ISLAND 
By Andrew Halkett 
This collection, made by Mr. J. D. Soper and referred to me for iden- 
tification, consists of a Northern pollack, two species of sticklebacks, two 
species of sculpins, and an Arctic char, and comprises numerous specimens. 
The identification, w r ith proviso placed below the list, is as follows: 
Northern pollack (Boreogadus saida) 
Arctic stickleback ( Pygosteus pungitius brachypoda ) 
Common stickleback ( Gastrosteus aculeatus ) 
Greenland sculpin ( Myoxocephalus groenlandicus ) 
Long-horned sculpin ( Oneocottus hexacornis ) 
Arctic char ( Salvelinus alpinus ) 
Of the northern pollack, of which there is one specimen, nothing fur- 
ther need be said. 
Of the sticklebacks there are, as shown in the list, two species. The 
former, which in my Check-list I denominated the Arctic stickleback, 
I give under the trinomial: Pygosteus pungitius brachypoda, but it may be 
questionable whether or not the arctic form is entitled to subspecific rank. 
At most it is evidently only a variety of the nine-spined stickleback which 
has a very wide distribution in Canada. The average number of dorsal 
spines in the specimens of the collection may be placed at about ten, but 
there are individuals in the collection with the number of spines below or 
above ten. This, however, is not of great consequence, for the sticklebacks, 
many of which at least can live equally well in fresh, brackish, or salt water, 
are subject, even individually, to great variation. In regard to the latter 
(Gastrosteus aculeatus), there is in my Check-list a note: “G. aculeatus 
and G. bispinosus are treated here as one and the same species, the Euro- 
pean name being adopted for the two/’ and I know of no modification of 
structure to warrant the separation of the common stickleback, which has 
a wide distribution in northern Europe and northern America, into separate 
species or subspecies. In the collection there are two adult and about 
two dozen very young specimens of this stickleback. 
The Greenland sculpin by some has been regarded as being identical 
with the European sculpin (Myoxocephalus scorpius), but this has been 
disputed by others. I have, therefore, as the question is pending, placed 
the specimen in the collection provisionally in the list under the technical 
name Myoxocephalus groenlandicus. 
The second mentioned sculpin is quite probably circumpolar in its 
distribution, and may not be essentially different from the European 
sculpin Oneocottus quadricornis. I placed the presumed northern species 
in my Check-list as Oneocottus hexacornis with a footnote: “0. hexacornis, 
0 . quadricornis, and 0 . labradoricus provisionally treated here as one and 
the same species,” but am not clear as to the identification of the specimen, 
having little to go by except descriptions which are not very decisive and 
records some of which are very old.
