new Fera from Asia and Africa. 89 



Ilab. N. Siam. Type from the Chiengdao Cave, 50 miles 

 north of Chiengmai. Alt. 350 m. 



Type. Adult male (skin in spirit). B.M. no. 13. 4. 18. 3. 

 Collected January 1913. Presented by Th. H. Lyle, Esq., 

 II. B.M. Consul at Chiengmai. 



The Sze-chwan Hipposideros pratli being as yet only 

 known from the type specimen, a female, and the present 

 example being a male, it at first sight seemed possible that 

 we had here the unknown male of that species. But further 

 examination shows such differences as to render this im- 

 possible, notably the smaller general size, the much smaller 

 teeth (this in a male as compared with a female), and the 

 development of the pendant lappets at the front edge of the 

 horseshoe, not at all likely to be a sexual character. 



The type-specimen was obtained in a cave in company 

 with examples of //. armiger, as also happened curiously 

 enough with the type of H. pratti. 



This adds another to the many new Siamese mammals 

 discovered by Mr. Lyle, and I have had great pleasure in 

 connecting his name with it.
