Acerodon jubatus, Eschsc h.

Specimens exa mined.—Nineteen from the collections of the Berlin, U.S. National, and British Museums, viz.:—Luzon, ten, including the two cotypes of Pt. yijrrhocephalus (Berlin Museum, nos. 310, 311, ♂ ad., ♀ ad., mounted, skulls separate, that of 340 (marked 7202) being the original of Meyen's skull figures, I. s. c.); “ Philippines ” (probably Luzon), two; Leyte, three, topotypes of Pt. auri-nucbalis; Negros, two; Dinagat, one; Mindanao, one.

Remarks.—An examination of the above material has satisfied me that the Philippine Isl a n d s are inhabited by two raees of A. jubatus, the one distribute d over all the islands from Luzon southward to Dinagat (specimens examined from Luzon, Leyte, Negros, Dinag it), the other confined to Mindanao. The Mindanao race differs from typical jubatus only by its larger average size. There is no tangible differ ­ ence in the colour of the fur of the two races. Such variations in eolour as do occur (more blackish or more dark brownish tinge of back, greater or lesser amount of pale sprinkling of underparts, blackish or chocolate tinge of foreneck, more creani-bufly or yellowish-buffy or ochraceous-buffy colour of nuchal patch) are perfectly individual, independent of sex, age, and locality; practically all colour-variations are repre ­ sented in the series of ten specimens from Luzon.

The subjoined tables (pp. 27-29) give a summary of the measurements of the series of specimens.

According to the above, the two races of A. jubatus would have to stand as follows: —
