Miniopterus schreibersii japoniae Thomas. 



Compared with M. blepotis, which appears to be the nearest ally of the Japanese 

 species, M. s. japoniae differs strikingly in its large foot and very short, broad ear. 

 The tibia and forearm are also slightly larger, and the thumb is stouter. The dif- 

 ferences are absolutely small, but relatively large, and result in a very different 

 appearance of these parts. Two specimens from Mt. Fuji, Japan, measure re- 

 spectively: forearm, 46.5, 47; ear from meatus, 10, 10.5; tibia, 18, 91; foot, 

 9, 9.8. 



Bonhote has recently described M.fuscus from the Loo Choo Islands, but this 

 bat belongs to the group of smaller eastern Miniopteri, and is of a uniform sooty 

 brown to the bases of the hairs. Whether or not there is a representative of the 

 smaller group in Japan, has not yet been ascertained. In Europe the larger 

 group seems to be alone represented.

Temminck (Monogr. Mammalogie, 1835, vol. 2, p. 212) applied the name 

 Vespertilio blepotis to specimens of Miniopterus " tues a Java, a Timor et a 

 Amboine," and he considered Japanese specimens identical with these. He gives 

 the measurements (here converted into millimeters) as : total length, 106.5 ; tail, 

 51.8 ; forearm, 46-48. Farther on he states that females are smaller, with fore- 

 arm two to three lines shorter, but this statement probably refers to the smaller 

 species that also occurs in Java. Of the latter Mr. Thomas Barbour has recently 

 presented to the Museum three males and three females collected by him at 

 Buitenzorg, Java. The larger species, however, he did not obtain on that island, 

 although he found it on Amboina, considerably to the eastward, where a single 

 adult female was captured in a limestone cave. This bat corresponds closely 

 with the original description, and doubtless represents Temminck's blepotis. 

 This name should stand for the large Miniopterus of Java and the islands to the 

 eastward, and possibly west to the southeastern coasts of Asia, for a specimen 

 from Amoy, China, in the mounted collection of the Museum, is externally iden- 

 tical with our individual from Amboina. This latter, an alcoholic, No. 6920, 

 measures as follows : head and body, 53; tail, 55 ; ear, 13 ; tragus (inner mar- 

 gin), 5; forearm, 45.5; thumb, 5.8; 2d digit, metacarpal, 39; 3d digit, meta- 

 carpal, 40.5 ; 1st phalanx, 10 ; 2d phalanx and tip, 39 ; 4th digit, metacarpal, 

 38.5; 1st phalanx, 8.8; 2d phalanx and tip, 17.5; 5th digit, metacarpal, 35.2; 

 1st phalanx, 8.6; 2d phalanx and tip, 9; tibia, 17; foot, 7-5; calcar, 16. The 

 skull measures : greatest length, 16.2 ; basal length, 14 ; palatal length, 8.4 ; 

 interorbital constriction, 3.7; zygomatic breadth, 9.5; mastoid breadth, 8.6;
