AND ODONTONYCTERIS. 137 



mens have been collected by voii Rosenberg in the Aru- 

 islands (Wokam), in the Berlin Museum there are a Macro- 

 glossus-c^ and a Syconycteris-(S^ from the same island, Wokam, 

 and also from v. Rosenberg's collections. The Dresden- 

 specimens and a male from the Ley den Museum I bring 

 under the heading Macroglossus nanus, the somewhat larger 

 (f and 9 from the Leyden-collection are Syconycieris papu- 

 a72a-specimens. Accordingly to Matchie there is a difference 

 in the seventh palate-ridge between his Wokam-cf and the 

 the specimens from New Guinea viz: the seventh » verlauft 

 fast geradlinig nur ganz schwach nach vorn gebogen und 

 ist in der Mitte nicht stumpfwinklig geknickt". As there 

 nearly always are individual variations we should not 

 attach too great importance to such small differences ; in 

 our cf the seventh palate-ridge is much more triangularly 

 shaped than in our Q, and there are even small differences 

 in the length of muzzle, fore-arm, second and third finger, 

 but they are all of subordinate importance. There are no 

 two animals exactly alike in- and outside as little as two 

 leaves of a given tree are alike in all minute details. In 

 size the Aru-specimens of Syconycieris are much smaller 

 than the New Guinea-specimens (from the Dresden- and 

 Berlin Museum) in all their dimensions, besides other small 

 differences, f. i. the lobule at the base of the outer margin 

 of the ear is very minute and rounded off, the grooves in 

 the upperlip vary a little, a. s. o. ; the material however at 

 present at hand is too small to loose here the specific 

 question ; we want fresh specimens.
