Acerodon juhatus, Eschsch. 



Specimens ex tunned. — Nineteen from the collections of the 

 Berlin, U.S. National, and British Museums, viz. : — Luzon, 

 ten, including the two cotypes of Pt. pyrrhocepkalus (Berlin 

 Museum, nos. 340, 341, <S ad., ? ad., mounted, skulls 

 separate, that of 340 (marked 7202) being the original of 

 Mej-en^s skull figures, I. s. c.) ; "Philippines" (probably 

 Luzon), two; Leyte, three, topotypes oi Ft. auri-nuchalis ; 

 Negros, two ; Dinagat, one ; Mindanao, one. 



Remarks. — An examination of tiie al)Ove material has 

 satistied me that tiie Philippine Islands are inhabited by two 

 Yi\.ceB oi A. jubatus, \\iQ one distributed over all the islands 

 from Luzon southward to Dinagat (specimens examined 

 from Luzon, Leyte, Negros, Dinag.it), the other confined to 

 J\]indanao. The Mindanao race ditfers from typical juhatus 

 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 colour 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 

 cream-bufFy or yellowish-bufFy or ochrac^ous-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 : —
