Two specimens of M, o. oregoni from the north base of Three Sisters, 
5,000 feet, in the Cascade Mountains of Oregon (nos. 204,722, d', and 
204,718, d’, U. S. Nat. Mus., Biological Survey collection) are larger 
than the typical form, and may be referable to cantwelli. 
I am indebted to Prof. W. T. Shaw, in charge of the museum. State 
College of Washington, Pullman, Washington, for the loan of material. 
GENERAL NOTES 
SOME NOTES CONCERNING THE MASTIFF BAT 
In Mr. A. B. Howell’s recent paper on bats, the remark is made that, after 
trying various methods, he did not succeed in making the mastiff bat {Eumops 
calif ornicus) fly (Journ. Mamm., vol. 1, no. 3, p. 112, 1920). I had the oppor- 
tunity to study several of these bats taken with Mr. Howell at Colton, Riverside 
County, California. The bats were placed in a large screen porch where there 
was ample room for them to fly. One afternoon while trying various experi- 
ments with the animals, I succeeded in making one bat take wing from the floor. 
It flew up about two feet and made a semicircular flight of about ten feet and 
then lunged to the floor again. This attempt looked rather encouraging, but as 
hard as I tried, I could not make the bat fly again. On warm days the bats were 
very active, and when disturbed they scampered about seeking a dark corner, or 
something to crawl under. When they bumped into the wall, or any perpendicu- 
lar object, they began to climb head forward until off of the floor, and then 
turned and climbed backwards, pulling with each foot alternately.

AS TO THE WOLVERINE 
The story which tells that the “glutton” or wolverine secures its prey by 
lying in wait on the branches of a tree for a deer to pass under it and dropping 
on the deer’s back and killing it has been the text for not a little jocular writing. 
Coues laughed at it and says of the wolverine, “It is imperfectly plantigrade and 
doe-' not climb trees like most of its allies.” Most people regard the tale as 
fable. Is it so, or has it — like many other traditions — a basis of fact? 
Little seems to be known of the wolverine’s habits. A few trappers have told 
of the mischief it does along the trap line, but except for that, not much has been 
written of its ways of life; and of what has been told, almost none is at first 
hand. The animal seems hardly to have been observed by naturalists. 
It is generally stated that the wolverine does not attack large animals, but. 
lives on grouse and rabbits and other small creatures. This means only that 
because — in the opinion of the writers — it is not sufficiently active to catch 
them, therefore it does not attack large animals. It will subsist on whatever 
food is most easily accessible and this may cover a wide range of species, from.
