Dobsonia viridis umbrosa, subsp. n. 



All essential characters as in D. viridis of the Kei Islands, 

 but the colour averaging darker throughout. In the most 

 marked specimens the crown is blackish "bistre" instead of 

 " raw umber/' the nape is a lighter shade of bistre instead of 

 bright yellowish or " raw sienna," and the under surface near 

 "mummy-brown" instead of "tawny olive" or "clay- 

 colour." 



Forearm of type 118 mm. 



Hub. Ceram. 



Type. Adult female. B.M. no. 7. 1. 1. 259. Collected in 

 1859 by A. R. Wallace. Purchased with the Tomes Collec- 

 tion. 



Although in rare instances the Ceram Dobsonia has the 

 bright coloration characteristic of the typical Kei D. viridis, 

 the colour of the majority of specimens is so much darker 

 that it should apparently have a definite subspecific name. 

 Besides five specimens of umbrosa collected by Mr. Wallace, 

 the Museum possesses a number of both Aru and Ceram 

 forms obtained by the late Mr. W. Stalker. 



Myolis [Leuconoe) stulkeri, sp. n. 



A large species with enormous feet; no interfemoial fringe. 



ISize large, about equalling that in M. pequinius, therefore 

 alone exceeded among Old- World members of Leuconoe by 

 the Chinese M. riclcetti. Fur very soft, fine, and velvety ; 

 hairs of back about 6 mm. in length. General colour a 

 variable greyish brown with silvery gloss, the hairs blackish, 

 with dark " broccoli-brown " tips ; head rather greyer. 

 Under surface strongly contrasted creamy whitish, the hairs 

 slaty for two-thirds their length. Limbs and membranes 

 uniform pale brown, naked throughout except just at the base 

 of the tail; interfemoral without a fringe, though there are a 

 few scattered hairs along its posterior border. 



Ears of medium lenglh; tragus long, narrow, pointed, with 

 a well-marked external basal lobule. Feet exceedingly large, 

 their proportionate size seeming to increase in this genus in 

 the larger species. 



Skull large, of normal shape. Middle upper premolar 

 about half the size of the anterior, shut in in the internal 

 angle between the other two. Middle lower premolar of the 

 same proportionate size as above, but in the tooth-row. 

 Other teeth as usual.
