Hab. N. Siam. Type from the Chiengdao Cave, 50 miles north of

Type. Adult male (skin in spirit). BM. no. 13. 4. 18. 3. 
Collected January 1913. Presented by Th. H. Lyle, Esq., H.B.M. 
Consul at Chiengmai. 
The Sze-chwan Mipposideros pratti 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 impossible, notably the smaller general size, the much 
maller 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 H. armiger, as also happened curiously enough with the 
type of H. pratt. 
This adds another to the many new Siamese mammals discover- 
ed by Mr. Lyle, and I have had great pleasure in connecting his name 
with it.
