ALLEN : NOTES ON CHIROPTERA. 43 



men of T. albiventer the hairs are slightly darker at their bases than at their tips. 

 This specimen does not seem to have become faded appreciably, notwithstanding 

 its exposure in an exhibition case. The tail, as in T. disci/era, extends apparently 

 just beyond the posterior border of the interfemoral membrane, thus differing from 

 T. tricolor, in which from "one fourth to one third" is free from the interfemoral 

 membrane. The third and fourth digits of the pes appear to show syndactylism, 

 as in T. disci/era, though in the specimen as mounted this is a trifle difficult to 

 determine. The measurements of our Ecuadorean specimen are not sensibly dif- 

 ferent from those of T. disci/era. 



VESPEBTTLIONIDAE. 

 Myotis adversus (Hoksfield). 



A single female, alcoholic, No. 6S69, was collected by Mr. Thomas Barbour at 

 Buitenzorg, Java, and by him presented to the Museum. It measures as follows : 

 head and body, 46 ; tail, 38 ; ear, 16 ; tragus, 6.6 ; forearm, 37 ; thumb, 6 ; 2d 

 digit, metacarpal, 32 ; 1st phalanx, 3.6 ; 3d digit, metacarpal, 36.6 ; 1st phalanx, 

 14.5; 2d phalanx and tip, 19; 4th digit, metacarpal, 35; 1st phalanx, 10; 2d 

 phalanx and tip, 11 ; 5th digit, metacarpal, 34; 1st phalanx, 8 ; 2d phalanx and 

 tip, 9; tibia, 16; foot, 10; calcar, 14. Skull: greatest length, 15.5; basal 

 length, 12.7 ; palatal length, 8 ; interorbital constriction, 3.5 ; zygomatic breadth, 

 9.4; mastoid breadth, 7.8; mandible, 11; maxillary tooth row (exclusive of in- 

 cisors), 5.8 ; mandibular tooth row (exclusive of incisors), 6.1. The large foot of 

 this species is in marked contrast to the small delicate pes of M. muricola, which 

 also occurs at Buitenzorcr.

Myotis gOUdoti (Smith). 



The collection contains two alcoholic females from Madagascar, Nos. 5986, 

 5987, whose measurements, on account of the paucity of such data, are here 

 given, the second measurement in each case being that of No. 59S7 : head and 

 body, 44,44; tail, 40.5, 42; ear, 17, 16; tragus, 6.5, 6; forearm, 41, 38.5; 

 thumb, 7.7, 8.2; 2d digit, metacarpal, 37, 34; 3d digit, metacarpal, 38, 35; 1st 

 phalanx, 13.6, 12 ; 2d phalanx and tip, 19.6, 19 ; 4th digit, metacarpal, 38, 34; 

 1st phalanx, 10.5, 10; 2d phalanx and tip, 11, 10; 5th digit, metacarpal, 36, 

 33.5 ; 1st phalanx, 9, 9 ; 2d phalanx and tip, 9, 9.8; tibia, 17, 16 ; foot, 10.6, 9; 

 calcar, 13.8, 14.2. The skull of No. 5986 measures: greatest length, 15.5; 

 basal length, 13 ; palatal length, 8 ; interorbital constriction, 3.5 ; zygomatic, 

 breadth, 9.8 : mastoid breadth, 8 ; mandible, 11.5 ; maxillary tooth row (exclu- 

 sive of incisors), 6 ; mandibular tooth row (exclusive of incisors), 6.2. 



Myotis muricola (Hodgson). 



Two specimens from Sarawak, Borneo, are referable to this species, as well as 

 a series of fourteen from Batavia and Buitenzorg, Java, collected by Mr. Thomas
