ARTICLE XI. Notes on Collections of Mammals made in Central 

 and Southern Mexico, by Dr. Audley C. Butter, with Descrip- 

 tions of New Species of the Genera Vespertilio, Sciurus, and 

 Lepus. By J. A. ALLEN. 



Since the publication, in October, 1889, of my report on the 

 first collection of mammals made by Dr. Buller in Mexico, the 

 American Museum has received from him two additional collec- 

 tions, containing many species not included in his first shipment, 

 among them several apparently new to science. To make the list 

 complete to date, all of the species thus far received from Dr. 

 Buller are mentioned in the present paper, those contained in the 

 former paper being here briefly entered, with a reference to the 

 fuller record already published. 



Dr. Buller's collection of mammals numbers 238 specimens, 

 representing 46 species and subspecies, of which seven proved 

 new to science. Several others were new to the fauna of Mexico, 

 and the habitats of others are extended much beyond their pre- 

 viously known limits. Finally, it is safe to say, Dr. Buller's collec- 

 tion of Mammals is one of the most extensive and important ever 

 received from Mexico from any single collector. 



In the preparation of this paper I have been greatly indebted 

 to Dr. C. Hart Merriam, Chief of the Division of Economic 

 Ornithology and Mammalogy of the United States Department 

 of Agriculture, for the loan of material, and especially for the 

 opportunity of comparing some of the obscure species of Vesper- 

 tilio and Hesperomys with the types of species recently described 

 by him from Arizona, and also with De Saussure's types of all the 

 latter's Mexican species of " Hesperomys," fortunately just at 

 present in Dr. Merriam's possession, De Saussure's types having 

 been generously loaned him by the authorities of the Musee 

 d'Histoire Naturelle de Ville de Geneve for examination. I am 

 also indebted to Mr. F. W. True, Curator of the Department of 

 Mammals in the United States National Museum, for the oppor- 

 tunity of examining other authentic specimens of De Saussure's 

 species (some of them labeled by De Saussure himself), and also 

 the type of Dr. Coues's Hesperomys melanophrys, as well as a good 

 series of Merida specimens of Lepus.
