 longer in the winter than in the summer, though the ditierence 

 does not approacii that which obtains in Persian Onagers 

 and Kiangs, and there is a decide I ditference in colour. The 

 summer coat is a clear grey, which gradually turns to a sandy 

 fawn as the season advances, the ditference in tint between 

 the two being very marked when the old sandy-fawn coat 

 conies away and shows the new stone-grey coat beneath it iu 

 patches at mouiting-time. 



LXVI. — On the Fruit-Bats uf the Genus Dobsonia. 

 By Knud Andersen, F.Z.S. 



The subjoined notes and descriptions are based on ninety- 

 one specimens in the collections of the Leyden, Berlin, 

 Paris, and British Museums. The three former Museums 

 were visited by me in August and September this year, and 

 I have much pleasure in taking this opportunity of acknow- 

 ledging my indebtedness to Dr. Jentiuk, Professor Matschie, 

 and Professor Trouessart for the liberal way^ in which they 

 placed the collections under their charge at ray disposal. 

 The large series of Dobsonia from the Dutch East Indies 

 preserved in the Leyden Museum has been of special im- 

 portance for my revision of the genus. 



The latest reviser (Matschie, 1899) recognized only one 

 species of Dobsonia. The total number of species briefly 

 diagnosed below is twelve, six of which are new. 



The notes are preliminary to a completer account of the 

 genus in the British Museum Catalogue of JSIegachiroptera 

 now under preparation.

1810, Pteropus pal[l]iatus, E. Geoffroy, Ann. Mus.d'Hist. 

 Nat. XV. p. 99. In 1825 by Temminck put down as the 

 young of Cephalotes jjeroni [Dobsonia pe?'07iij (Mon. Mamm. 

 i. pp. 169, 170), a view accepted also by the original describer 

 iu lb28 (Cours d'Hist. Nat. Mamm., 13 le9ou, pp. 29, 30), 

 as well as by all later revisers of the genus. — It is evident 

 from Geofl'roy's description that the type of Pt. palUatus was 

 a quite young Dobsonia with the milk-incisors (l^g) *^ *^^"« 

 As the type locality is unknown, the description confined to
