MAMMALS OF THE NATUNA ISLANDS I37 



of incisor) 6.8 (9) ; mandibular toothrow (exclusive of incisors) 7 



(9-8). ^ 



Specimens examined. — Three (one skin), all from the type locality. 



Remarks. — Rhinolophus spadix is so readily distinguished from 

 its relatives of the R. affinis group that it needs no special comparisons. 

 It is a much smaller animal than the species from the Anambas that I 

 recently referred to R. rouxii.^ In color the latter is a dull brown not 

 in the least resembling the russet of R. spadix. 



CYNOPTERUS MONTANOI Robin.

 p. 655. September, 1894 (Sirhassen and Bunguran).

 seums fiir Naturkunde, p. 75. August, 1899. (Natuna record of C. 

 marginatus placed in synonymy of C. montanoi.') 



Five specimens (three skins) from Sirhassen. These agree so 

 closely with a skin and two bleached alcoholic specimens from Sing- 

 apore, which I suppose to be the same as the Malaccan Cynopterus 

 montaftoi., that without more material it is impossible to distinguish 

 the Natuna animal from that of the southern extremity of the Malay 

 Peninsula. Cynopterus montanoi as thus understood differs from C. 

 angulatus Miller^ of Lower Siam in its more slender skull and in the 

 absence of the white border of the ear, and from C. titthcecheilus 

 (Temminck) of Sumatra and Java in its conspicuously smaller size. 



PTEROPUS VAMPYRUS (Linnjeus). 



1894. Pteropus va7npyrus Thomas and Hartert, Novitates Zoologicas, i, 

 p. 655. September, 1894 (Bunguran). 



1895. Pteropus vatHpynis Thomas and Hartert, Novitates Zoologicce, 11, 

 p. 489. December, 1895 (Bunguran). 



Six skins from Bunguran. 



.? PTEROPUS HYPOMELANUS Temminck. 



1894. Pteropus hyponielatius Thomas and Hartert, Novitates Zoologicae, 



I, p. 655. September, 1894 (Sirhassen). 



1895. Pteropus hypomelayius Thomas and Hartert, Novitates Zoologicae, 



II, p. 489. December, 1895 (Pulo Pandak, Pulo Panjang and Pulo 

 Laut). 



Eight (one in alcohol) from Sirhassen and seven (one in alcohol) 

 Pulo Laut. It is highly probable that these specimens represent a 

 species distinct from the true Pteropus hypo7nelanus of Ternate.
