4. 11. 25. = 1074. Mlnas Gerae?. (As 559.) 

 Bz. 9. 3. 2C). = 1075. Rio do Janeiro. 



This specimen bears West\vood^s number N. 4 ; his list 

 adds another, captured 26. 11. 26 at Santos. 



These two species, originally placed under one number 

 (N. 4) in a clerk's handwriting, were differentiated by West- 

 wood, who placed the examples of lethe under a new number 

 (N.4*).

IV. — Notes on the Gemis Acerodon, with a Synopsis of its 

 Species and Subspecies, and Descriptions of Four new 

 Forms. By KXUD AXDERSEN. 



The Genus AcERODON. 



Type. — Pteropus juhaius, Eschscholtz. 



Species. — Six (nine recognizable forms), viz. A. mackloti 

 (three subspecies), gilvus, celebensis, humilis, lucifer, Jubatus 

 (two subspecies), 



lianye. — Timor group (Timor, Flores, Alor, Sumba) ; 

 Celebes group (Celebes, Selayar) ; Talaut Islands ; Philip- 

 pines*. 



Differential characters. — Acerodon differs from Pterojius by 

 the combination of the following dental characters : (1) Poste- 

 rior basal ledge of />4, Wj) ^nd m^ extending along inner base 

 of teeth as a broad, sharply defined shelf; this character is 

 sufficient to distinguish Acerodon from any species o^ Pteropus .^ 

 except Pt. anetianus, which possesses a perfectly similar inner 

 basal ledge in the same teeth, but in every other respect is 

 closely allied to the genuinely Pteropine Pt. samoensis : 

 (2) a well-developed antero-internal basal cusp in p* and 

 m^ (a similar, but smaller, antero-internal cusp developed in 



* The range of the " subgenus " Acerodon is stated by Matschie to be 

 the Philippines, Gilolo, Batjan, Celebes, flores, and Timor (Megachir. 

 p. 99, 1899), and essentially the same distribution is given by Miller 

 (Fam. & Gen. Bats, p. 59, l'907). Gilolo and Batjan must be excluded 

 from the known range of the genus. The records of Acerodon from the 

 Gilolo group are based on mistaken identifications of Gray's Pteropus 

 caniceps and his Pteropus mackloti var. batchiana ; the latter name is a 

 synonym of the former, and Pierc^ms caniceps a perfectly typical Pterop^ts.
