species. It is the smallest of the eastern species hitherto recognized, aud, ac- 

 cording to Tomes, is " very similar " in color to M. blepotis, but usually with 

 "a more decided rufous tinge," owing to the reddish tips to the hairs. The 

 measurements of our two specimens follow; they are No. 6764, adult female, 

 and No. 6765, adult male, and their respective dimensions are in each case given 

 in this order: head and body, 45, 47-5 ; tail, 44, 46; forearm, 40, 38.5; thumb, 

 4.8,4; 3d digit, metacarpal, 35, 34; 1st phalanx, 8.7, 9.8; 2d phalanx and tip, 

 31, 31.5; 4th digit, metacarpal, 34, 33.3; 1st phalanx, 7.5, 7-5; 2d phalanx 

 and tip, 15.5, 15.6; 5th digit, metacarpal, 31.5, 31; 1st phalanx, 7.3, 7.5; 

 2d phalanx and tip, 8, 8.5; tibia, 15.6, 14.7; foot, 7, 7; ear, 9.2, 10. The 

 skull of No. 6764 measures : greatest length, 14 ; basal length, 12 ; palatal 

 length, 6.6 ; iuterorbital constriction, 3.7 ; zygomatic breadth, 7-6 ; mastoid 

 breadth, 7.8 ; mandible, 10.5 ; maxillary tooth row (exclusive of incisors), 5.4; 

 mandibular tooth row (exclusive of incisors), 5.8. The rostrum is slightly longer 

 and the braincase smaller and less inflated than in M. pusillus, which it nearest 

 approaches in size. 



Murina hilgendorfi (Peters). 



Among the Japanese bats presented by Mr. Thomas Barbour is an alcoholic 

 male of this species, collected on Mt. Fuji, Japan, December 14, 1906. The type 

 specimen came from Yedo, and is well figured and described by Peters (Monats- 

 ber. konigl. preuss. Akad. Berlin, 1880, p. 24, plate), but I have found no record 

 of tlie discovery of other specimens. The measurements of our specimen. No. 

 6924, foUow, and in some cases are accompanied by the corresponding dimensions 

 given by Peters for the type: head and body, 54; tail, 41; forearm, 43 (41); 

 thumb, 12 ; 2d digit, metacarpal, 36 (34.5) ; 1st phalanx, 4.5 (4) ; 3d digit, 

 metacarpal, 40 (38); 1st phalanx, 17 (18); 2d phalanx, 15 (15); 3d phalanx 

 (cartilage), 7-6 (8.5) ; 4th digit, metacarpal, 37-5 (36) ; 1st phalanx, 14 (14) ; 

 2d phalanx and tip, 12.5 (13.5) ; 5th digit, metacarpal, 37.5 (37) ; 1st phalanx, 

 14(13.5); 2d phalanx and tip, 13 (12); tibia, 17.8 (17); foot, 8.5; calcar, 

 13.5 (14); ear, 17.5 (17); tragus, 7.8 (10). The skull measures: greatest 

 length, 20; basal length, 16.2 ; palatal length, 10.5 ; interorbital constriction, 5 ; 

 zygomatic breadth, 11.5; mastoid breadth,' 10; mandible, 14; maxillary tooth 

 row (exclusive of incisors), 6.5 ; mandibular tooth row (exclusive of incisors), 7. 



The fur is thick and woolly, and appears to be like that of Peters's specimen, — 

 bright brownish above, and gray-white tipped, with dark bases below. 



Kerivoula hardwickii (Horsfield). 

 A single specimen was obtained by Mr. Thomas Barbour at Buitenzorg, Java. 



MOLOSSIDAB. 

 Chaerephon plicatus (BncHAXNAN). 

 Mr. Thomas Barbour obtained a fine series, including both sexes, from Buiten- 

 zorg, Java. It is a house bat, often found in the interstices of buildings. One
