3i8 Notes on a Collection of Mammals. [zoe 



When it is recalled that at Red Point and Blue Canon, Tam- 

 ias iuacroj'habdoies 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 T. quadrimacii- 

 latus, 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 T. 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 T. quadrimaadatus 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.
