DESCRIPTIONS OF APPARENTLY NEW SPECIES AND SUBSPECIES 

 OF MAMMALS FROM CALIFORNIA, OREGON, THE KENAI 

 PENINSULA, ALASKA, AND LOWER CALI- 

 FORNIA, MEXICO. 



BY D. G. ELLIOT, F. R.S.E., ETC. 



The forms described in this paper, with the exception of the mink 

 from the Kenai Peninsula, Alaska, and the mouse from St. Catalina 

 Island, California, were obtained by Mr. Edmund Heller, Collector 

 for the Museum, along the coasts of California and Oregon in 1901, 

 and in the Peninsula of Lower California in 1902, both in the low 

 lands and in the mountain ranges of Hanson Laguna and the San 

 Pedro Martir. A complete catalogue of the collections obtained on 

 these expeditions will be published later with Mr. Heller's notes upon 

 the various species procured. In the troublesome genera Thomomys 

 Microtus and Perognathus, I have been assisted by Dr. Merriam, 

 Mr. V. Bailey, and Mr. W. H. Osgood of the Biological Survey, 

 Washington, who have kindly compared a number of my specimens 

 with the types and examples in the great collection in Dr. Merriam's 

 charge, and to whom I desire to express my thanks. The measure- 

 ments given in this paper, except some of Myotis tnilleri and Putorius 

 r. melampeplns, are those of the collector's taken in the flesh.
