species, ami that it was only by a slip of the memory that he gave 

 it a name which lie had, fourteen years earlier, proposed for a 

 different species of the geiuis. In 1870 (Cat. Monk. &c. p. 110, 

 under the synonyms of Pl.hi/pomelas) he had discovered the lapsus, 

 but now committed the error to identify the A.ru bat with the 

 widely different Ft. ht/poindaniis, Temm., the technical name of 

 which he wrote Pt. hypomehis. 



Plerojjiis r.i l't)i<>po[/on var. aniejisls, Peters ; 1SG7. — -Type : J ad, 

 mounted, skull in situ, Am Islands, collected by Bernstein, acquired 

 by the Berlin from the Leyden Museum, lleg. no. 4962. The 

 figure of the skull iu the ' Megachiroptcra des Berliner Museums ' 

 {I. s. c.) is not drawn from the type, nor from the only other 

 specimen in the Berlin Museum (4703, Aru, Dr. Beccari) ; the 

 original may be a Leyden skull (?). — Dobson (Cat. Chir. 1878) 

 followed Peters, iu so far as he considered Pt.aruensis only a variety 

 of Pi. melanopo(ion, but with this variety he united Pt. keyensis. 

 Jentink's view (Cat. Ost., 1887; Cat. Syst., 1888) is only a slight 

 modification of Dobson's ; he recognized Pt. aniensis as specifi- 

 cally distinct from Pt. melanopogon, but uuited with the former 

 Pi. kei/eiisv;. Matschie (1899) recognized P<. nielanopojon, aruoisis, 

 and ke)jen.sis as distinct species, but the former he placed in the 

 subgenus Eimi/iUeris, the two latter in the subgenus Pteropus. 



Pterojius rubirfinosus, Hoscnherg; 1867. — Described by Rosenberg 

 as uniform " roestkleurig," darkest on head and neck, palest on 

 underparts, iris brownish red ; somewhat larger than '' Pt. argen- 

 toYies" [which in Rosenberg's writings is synonymous withPi. aruensis 

 and Pt. heijensis, as shown by a series of specimens from the Aru 

 and Key Islands in the Leyden Museum, collected by Rosenberg, 

 and labelled Pt. ar(jentatiis\ One example only, Wokam, Aru 

 Islands ; original number 23. In Rosenberg's manuscript Catalogue 

 preserved in the Leyden Museum this specimen (Wokam, no. 23) is 

 described as " roestgeel," larger t ban Pt. argentatiis, iris brownish 

 red, 9th April, perhaps a new species. The type is not in the 

 Leyden Museum. By Matschie {I. s. c.) referred, with a query, to 

 Pt. aruensis, but Rosenberg's brief notes (as quoted above) would 

 rather seem to indicate a species allied to Pt.jJapnanus. — Rosenberg's 

 ' Reis naar de Zuidoostereilanden ' (dated 1867) appears to have been 

 published late in 1867 or early in 1868, in either ease after the May 

 issue of the ' Monatsberichte ' of the Berlin Academy for 1867 which 

 contained Petcrs's description of Pt. melanoj^ogon var. artansis. 



Pteropus fiimigatus, Rosenbei'g ; 1867. — Described by Rosenberg 

 as " graauw-bruin " (in the German version, 1878, " einfarbig 

 rauchbraun ''), smaller than Pt. argentatu', iris brownish yellow; 

 common in Wonumbaj , Aru Islands. In Rosenberg's MS. Catalogue 

 of his collections (Leyden Museum) only one specimen is registered : 

 Wonumbay, no. ;')6, female, " grijsachtig bruin," below medium size, 

 iiis browni.sh yellow, 15th May. The type is not in the Leyden 

 Museum. By Matschie {l.s.c.) put down, with a query, under 

 Pt. aruensis, a suggestion certainly not supported by Rosenberg's 

 ijotp on the colour and size. Perhai)s a distinct species.
