318 Notes on a Collection of Mammals. [ZOE 
When it is recalled that at Red Point and Blue Cafion, 7am- 
tas macrorhabdotes only, seems to occur, it appears probable that 
this is the only species, or at least the most abundant one to be 
found at Michigan Bluff also. In connection with this we have 
the fact that neither in the original description of 7. guadrimacu- 
Jatus, nor in ‘Thomas’s later notes to Dr. Allen concerning the 
type specimen, is there anything characteristic. It is thus seen 
that Dr. Allen’s first impression that Gray’s species should be . 
identified with 7: macrorhabdotes has the probabilities greatly in 
its favor. Until the original type is more critically re-examined, 
or until Michigan Bluff is explored, it may be as well to follow 
Dr. Allen in identifying 7. guadrimaculatus with the species 
here so designated. 
2. Tamias macrorhabdotes Merr. Long-eared Chipmunk. 
Eleven specimens taken in the neighborhood of Red Point 
are all distinctly referable to this species, and show but little 
variation. All were taken in late June or early July and are in 
breeding pelage. Several of the females were nursing and one 
or two contained small embryos. 
The long-eared chipmunk is pretty well distributed on the 
Forest Hill Divide, and chipmunks supposed to be of this species 
were seen at altitudes varying from 3000 to 5500 feet. On top 
of the Divide a mile or two from Red Point is a fire-swept 
stretch of woods, with charred bushes and logs and trees both 
living and dead. The soil is a rich sandy loam supporting many 
species of flowering plants. In this locality the long-eared 
chipmunk is especially abundant. Sometimes a dozen could be 
seen at once playing on the logs and charred trees or scratching 
in the dust. My observations confirm those of Mr. C. A. Allen, 
who says that this animal is almost exclusively terrestrial, and 
that if it is surprised while on trees it will try in every way to 
reach the ground unseen and hide in holes or rubbish heaps. I 
have often seen it high up on trees, where it very skillfully 
reached the ground without being seen by descending the op- 
posite side. It has the usual shrill note of alarm, somewhat 
louder than those of other species I have met.
