liabitat not only Ueunion lait al&o Ternate. — Owiuo to a uiislakcn 

 identification of Brisson's first species of Fteropiis, tlie type of this 

 genus has hitherto been given as Fi. vnmpyrus (Merriam, Science, 

 (n. s.) i. p. 376, 1895 ; Miller, Fam. & Gen. Bats, p. b'o, 1907: 

 probably by a slip Matschie gives on p. 6 of his ' Megachiroptera ' 

 the type as Pt. conspiciUatus, on p. 12 && Ft. cdano = Ft. vampyrus). 



The genus Fteropus as understood by Dobson in his ' Catalogue of 

 Chiroptera ' (187S) corresponds to the genera Ftcropvs, Acerodon, 

 and Styloctenium of the present catalogue. The genus as hero 

 defined is equivalent to Fteropus and Desmcdopex in Miller's 

 ' Paniilies and Genera of Bats ' (pp. 56 and 60, 1907). 



Spectrum, Lacepede ; 1799. — Type (only species), '^ Spectrvm 

 vampirus." Linne's Vespertilio vamj^yims (1758) is a composite 

 species, including Ft. vampyrus, mger, and rufus. Of these, 

 Ft. niger uas apparently the only species known to the early 

 French mamnjologists from autopsy (see Brisson, /. s. c, and Bnffon, 

 Hist. Nat. X. p. 55, who distinguishes only two species of Fruit- 

 bats, the Koiissette, which is i;nquestionably Ft. niyer, and the 

 Rongette, which is Ft. suhmyer, l)oth from the Mascarenes), and 

 maj' therefore be fixed as the type of Lacepede's Spectrum. — In a 

 revised reprint of Lacepede's 'Tableaux methodiques,' published 

 in 1802 in the Didot edition of Buff'on (Quadr. xiv. p. 18S), Daudin 

 includes two species in the genus Spectrum, S. vampirus and 

 S. ruhidum ; the former is Ft. niger, the latter Ft. subniger. 



Euiiycteris, Gray; 1866. — Type (only species), '-Fteropus 

 phaioyjs," Tenim. Temminck's Ft. pJia-iojis, 1825 (Mon. Mamm. i. 

 p. 178), is Pt. rufus, E. GeolT., J 803 {Ft. edwardsi, E. Geoff., 

 1810); Temminck's Ft. pltaiopis, 1837 (Mon. Mamm. ii. p. 65), is 

 Ft. melanopogon, Peters. From Gray's diagnosis of Euvycterts 

 (only important characters: uings attached to the vertebral line, 

 the part over the back bald, or nearly so) it is clear that the 

 " P/. pliaiops'' which he proposed to separate generically from 

 Ft('rop)us is Ft. melanopogon.- — Eunycteris has been considered a 

 synonym of Fteropus by all authors except Jfatschie (ilegachir. 

 pp. 6, 11 ; 1899), who revived the name for a subgenus of Fieropnis 

 including four (in reality three) forms, Vt. melanopogoti, papuanus, 

 <hgfner [^neoJnberaicus I, and neohilernicus. I tail to see any 

 chaiactcrs that bind these three species together in contiadis- 

 iinction fo all other species of the genus, except the narrowness 

 of th« furred area of the back. Ft. jiajiunnus and neohilernieiis 

 are essentially -ditl'erent fiom Ft. 'inel(inopot,on in dentition, and the 

 latter species has no closer known allies than Ft. aruensis and 

 keyensie, which by Matschie were referred to the subgenus Fl(ropus. 



Spectrum, Gray ; 1870. — Founded by (jiray independently of 

 Lacepede's Spectrum, with which he was ajjparently unacquainted. 

 Separated from Fteropus on account of its round head, narrow face, 

 and small hidden ears. Five species : S. vulgar^ [Ft. niger; type 

 by subsequent designation: see Matschie, Megachir. p. 6 (1899)], 

 rnbricolJe [Pt. suhnir/er^, dasymallum, aneiionum, and levcnpierum. — 

 Name revived by Matschie (/. s. c.) for a subgenus of J'teropus
