ALLEN : NOTES ON CHIROPTERA. 



27 



from Sumatra is stated to show no indication of a whitish border to the ears, but 

 this character is plainly present in the alcoholic specimens obtained by Mr. Bar- 

 bour in Java, and is mentioned also by Temminck. A Javanese specimen skinned 

 out from alcohol agrees well in color with that described by the latter. 



MEASUREMENTS OF CYNOPTERUS TITTHAECHEILUS. 



In his original description, Temminck gives the following measurements (here 

 converted into millimeters): total length, 127; forearm, 76; distance from 

 anterior corner of eye to tip of nostril, " 7 lignes," or about 15.5. The forearm 

 measuremeut corresponds closely with that of our specimens, which are evidently 

 larger than those from Sumatra referred by Mr. Miller to this species. It seems 

 probable that the Sumatran bat is distinct. 



The following cranial measurements are from the skull of an adult male, 

 No. 6937, from Buitenzorg, Java : greatest length, 36 ; basal length, 32 ; inter- 

 orbital constriction, 6.5; zygomatic breadth, 23.8; mastoid breadth, 14; man- 

 dible, 28 ; maxillary tooth row (exclusive of incisors), 12.7; mandibular tooth row 

 (exclusive of incisors), 14. 



The collection also contains a mounted specimen labelled " Borneo," whose 

 thumb and (dried) ear are smaller, but otherwise it is practically identical with 

 this" species. Its range may eventually be found to be more extensive than at 

 present supposed. 



Ptenochirus lucasi (Dobson). 



Two alcoholic specimens from Sarawak, Borneo, agree well with the cliaracters 

 given by Dobson. 



Rousettus collaris (Illiqer). 



Two specimens, Nos. 6748, 9, 6749, ^, from Cairo, Egypt, seem to be this 

 species rather than R. aeffj/piiacus, and probably indicate nearly the northern 

 limit of its range. They are preserved in alcohol, and measure as follows : tail, 

 13, 15.5; ear from crown, 18, 18; forearm, 93, 95; thumb, 35, 35; 2d di^-it, 

 metacarpal, 47, 44.5; 1st phalanx, 9, 10; 2d phalanx, 10, 9.4; 3d digit, meta- 

 carpal, 62, 62; 1st phalanx, 41, 42; 2d plialanx, 56.4, 57.7; 4th digit, meta-
