Article XXV. A NEW D'EER AND A XE\Y LYNX 

 FROM THE STATE OF SINALOA, MEXICO. 



By J. A. ALLEN. 



A few years since, the Museum purchased a few mammals 

 from Mr. J. H. Batty, collected by him at Escuinapa, southern 

 Sinaloa, in December, 1895. Among the species represented 

 are Lepus insolitus Allen, Canis vigilis Merriam, and the Lynx 

 and Deer here described. Both are well-marked forms that 

 appear to have hitherto escaped notice.
