Mar. 1898. NORTH AMERICAN MAMMALS ELLIOT. 213 



from anterior end of nasals to supra-occipital, 24 mm. Greatest 

 zygomatic width, 13 mm. Length of nasals, 8.5 



Measurments, taken by the collector, W. W. Price, in the flesh, 

 of the type 9 procured at Pyramid Peak, Eldorado Co., Cali- 

 fornia: Total length, 217 mm.; tail, 124 ; hind leg, 32 ; ear, 14. 



Seventeen specimens from the following localities : 4, Pyramid 

 Peak, Eldorado Co.; i, Blue Lake, Alpine Co.; 4, Silver Lake, 

 Amidor Co.; 8, Hermit Valley, Calaveras Co. 



The nearest ally of this species is probably Z. t. montanus, 

 Merr. , and in general appearance they resemble each other, the 

 present one being, however, rather brighter on the flanks. There 

 is little difference in the general coloration, but the white tip to 

 the tail, varying from a trace to ^ of an inch in length, is a very 

 distinguishing mark. The difference in the white among speci- 

 mens is caused, I judge, by the tip of the tail having been broken 

 off. Dr. Merriam very kindly sent me skins and skulls of his Z. 

 t. montanus for comparisons, from Crater Lake, Oregon, which 

 were of great assistance. The skull of No. 79862 was that one 

 especially employed when comparing the two forms. It gives 

 me great pleasure to bestow on this new species the name of my 

 friend, Dr. J. A. Allen, Curator of Vertebrates in the Am. Mus. 

 Nat. History, New York, so well known for his works in this and 

 other branches of science.
