NILS GYLDENSTOLPE, THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



into Szechwan and Fokhien. The southern race which inhabits the Malay Peninsula, 

 northwards to Assam (Khasi Hills) has been separated by K. Andersen under the name 

 of Hipposiderus armiger debilis. The differences between this race and the true H. ar- 

 miger are, however, very slight (vide: Andersen, Ann. & Mag. Nat. Hist. ser. 7, vol. 17. 

 1906 p. 35—48). 



The specimens collected at Nong Bea were all obtained in a deep cave in a lime- 

 stone moimtain. The other specimens were shot just at dusk at the neighbourhood of 

 my camp at Doi Par Sakeng. 



From Northern Siarn another allied form has been described by Thomas under 

 the name of Hipposiderus lylei (Ann. & Mag. Nat. Hist. ser. 8., vol. 12. 1913 p. 88). 

 This species was foimd at the Chieng Dao cave together with Hipposiderus armiger 

 Hodgs. During my journey I also visited the Chieng Dao cave but at the time of my 

 visit not a single bat was observed though a thick layer of dung indicated that this cave 

 was inhabited by numbers of båts. 



Hipposiderus lylei is nearest related to Hipposiderus pratti Thos. from Szechwan, 

 though it is slightly smaller than that species among other particulars which makes a 

 specific separation between these two related forms necessary. 



Hipposiderus lylei has recently been obtained in the Northern Shan States why its 

 range seems to be confined to Northern Siarn, the Shan States and Upper Burma.

The Bicoloured Leaf-nosed Bat seems to be widely distributcd in Siarn and was 

 both obtained in the Northern parts of the country and in the Siamese Malaya. The 

 specimens from Chieng Mai were collected in an old pagoda outside the town in company 

 with Coelops frithii, Blyth. 



The specimen from Koh Lak was captured in my house in the village. 



The ears in this species are very large. The fur is very long and dense and of a 

 dark brown colour on the back, each hair being fulvous white at the base. The nose- 

 leaf is rather small and not very complicated.
