Fauna of Huachuca Mountains. — Many field naturalists have 

 visited this beautiful mountain range, but it continues to yield rare 

 and novel forms of animal life whenever explored. Unfortunately, 

 Mr. Flolzner reached the Huachucas (July 24) after the breeding- 

 season of birds was over, and in a year of phenomenal dryness, when 

 old pine trees died of drought, and birds were obliged to forsake 

 their usual haunts on account of lack of water to drink. This 

 likewise operated to increase the difficulty of finding land-shells, 

 although the molluscan fauna is rich. Mr. Holzner obtained a 

 new rabbit (Lepus floridanus holzneri) and a new pocket-gopher 

 (Thomomys fulvus intermedins) from the aspen /one at the top: 

 and his collections contain line -eric- of several rare animals. Of 

 batrachians, only a toad, tree-frog, and a frog (Bana virescens 

 brachycephala Cope) were observed. Principally through the exer- 

 tions of Maj. Timothy E. Wilcox and, to a less extent, those of Drs.
