Nyctymene major Dobson. 



N°. 234. Adult Ç. Lorentz River, September 15. 1909. 

 N°. 309. Adult (f. Alkmaar, October 6. 1909. 

 N°. 438. Adult (f. Alkmaar, January 1910. 



Nyctymene Bechstein 1800 antidates Cephalotes Geoffroy 18 10 and Bdeligma Matschie 1899. 



The forearm of N°. 309 measures 82 mm., of N°. 234 not more than 77 mm. Upperparts 

 of head and body of N°. 234 much lighter coloured than the same parts of the two maies. 

 I do not venture to décide whether this may be perhaps a sexual différence. The unequal spots 

 on forearms, wings and ears always hâve been described as „white", our travellers however 

 remark that they are „sulphur yellow". 



Kiodotus nanus Matschie. 



Adult Ç>. Lorentz River, September 2. 1909. 



Adult Ç. Alkmaar-Camp. Collected by the military exploration. 



After Mr. PALMER Kiodotus as spécifie title has the priority over Carponycteris, the 

 former antidating more than fifty years. 



Hipposideros muscinus O. Thomas et Doria. 



1 adult maie, 2 adult females and 2 young spécimens. Lorentz River, September 16. 1909. 



Our females hâve two inguinal teat-shaped appendages much more developed than the 

 pectoral teats. 



It seems that the maie hitherto never had been captured, so that our tf spécimen 

 perhaps is the first maie known ; it makes the impression of being adult, it is however a 

 good deal smaller than the females as the forearm measures 42 mm., while in the females 

 the forearm measures 48 and 47 mm. (apud THOMAS and DORIA 47 and 45 mm.). The 

 free end of the tail is much shorter in the maie than in the females, as short as in a 

 young female having a forearm of not more than 26 mm. 



Leuconoë adversus Horsfield. 



Adult Ç. Bivak Island, December 26. 1909. 



Adult çf and Q. Bivouac-ship „Ar-end", January 12. 1910. 



Adult cf. Bivak Island, February 16. 19 10. 



The length of the forearm varies in this species between 36' and 38 mm., and is there- 



fore very constant for a species with such a large distribution through the East Indian 



Archipelago and abroad, from Siam to Australia.
