Genus NYCTALUS Lesson 



NYCTALUS MAXIMUS AVIATOR Thomas 



Nyctalus maximuft aviator Thomas, Ann. Mag. Nat. Hist., ser. 8, vol. 8, 1911, 

 p. 380 (Tokyo, Iloudo, Japan). 



Specimens. — Four in spirits from Fusan, Korea, 



These examples are evidently indistinguishable from typical. 



NYCTALUS NOCTULA SINENSIS (Peters) 



Vesperus sinensin Peters, Monatsb. Akad. Wissensch. Berlin (1880), 1881, 

 p. 258 (Peking, Chihli, China). 



Specimen. — One in spirits from Hunan. 



Comparative material is lacking but it is likely that the present 

 example, of the noctula type, is closer to sdnensis than to labiata of 

 Nepal. Externally it is very close to typical European noctida but 

 the skull is somewhat smaller. 



NYCTALUS species 



Specwiens. — Two from Mount Omei, Szechwan. 



These comprise an immature and a newborn yoimg. The former 

 is at an indeterminate stage of growth and the skull is imperfect, but 

 it seems to belong to a smaller form than noctulu and possibly 

 represents an Asiatic race of leisleri. 



Genus EPTESICUS Rafinesque 



EPTESICUS SEROTINUS FALLENS Miller 



Eptesicus serotinus pallens Miller. Proc. Biol. Soc. Wash., vol. 24, 1911, 

 p. 53 (Chengyuanhsien, Kansu, China). 



Specime7is. — Seventeen : Cheng^'uanhsien, Kansu, 1 (the type); 

 Kuyuanchow, Kansu, 1; Haishuisan, 1, and 80 miles south of 

 Yenanfu, Shensi, 2; Tientsin, Chihli, 2; and Tsingtao, Shantung, 10. 



All but one of the Shantung specimens are juveniles. This one 

 and the Chihli examples are somewhat darker below than typical 

 pallens, but may be so allocated for the present. 



EPTESICUS SEROTINUS subspecies 



Specimens. — Six : Changshowkai, Hunan, 5 ; and one from Suyki, 

 whose province is unknown — possibly Fukien. 



Four of the Hunan specimens are alcoholics. The other two can 

 not be referred to pallens, for they are quite dark, with a different 

 quality of coloration, and the skull — especially that to the Hunan 

 skin — is. narrow and rather small. Evidently they are not ander- 

 soni, nor can they be called typical serotinus. Without additional
