the fur it approaches the former ; in the size of the skull it 

 appears to average smaller than either. 



Pteropus hypomelanus luteus, subsp. n. 



The palest race of the species. Back, rump, and flanks 

 same shade of brown (from nearly seal-brown to Mars-brown) ; 

 head, mantle, throat, foreneck, breast, and belly ochraceous 

 buff, buff, or cream-buff, with or without a brownish wash on 

 throat and anal region. Forearm 128-136 mm. 



Type. £ ad. skin and skull, Kiriwini Island, Trobriand 

 group, 15th Feb. 1895; collected by A. S. Meek; B.M. 

 96. 11. 5. 5. 



Specimens examined. Seven, in the collection of the British 

 Museum. 



Range. New Guinea ; Conflict Is. (Itamarina) ; Trobriand 

 group (Kiriwini) ; Woodlark I. 



Remarks. — The difference in colour between Pt. h. luteus 

 and any of the western races of the species (genitalis, enqanus, 

 condorensis, canus, lepidus, annectens, tomesi) is very great, 

 but the gap is completely overbridged by those races which, 

 step for step, through the Philippines (cagayanus), Celebes 

 (macassaricus) , and the Gilolo group (hypomelanus), lead, in 

 colour as in geographical habitat, up to luteus. The inti- 

 mate relationship between all these forms is further shown 

 by the fact that, save in the colour of the fur, they are in all 

 respects (in skull, teeth, ears, quality, distribution, and length 

 of fur, and external dimensions) indistinguishable from each 

 other, except enganus, which averages smaller, canus and 

 lepidus, in which the teeth average larger, and annectens, in 

 which the skull averages smaller. 



Pteropus satyrus, sp. n. 



Allied to Pt. hypomelanus, but with smaller eyes and longer 

 fur. Diameter of orbit 12*2 mm., against 12 7-132 in all 

 forms of Pt. hypomelanus ; length of fur of back 18-19 mm., 

 against 10-14 mm. in Pt. hypomelanus. — Back and rump 

 blackish seal-brown, thinly and evenly sprinkled with pale 

 greyish hairs, producing the general effect of a blackish 

 colour slightly lightened with greyish. Centre of breast and 

 belly golden buffy (type) or nearly cream-buff (paratype) ; 

 sides of breast and belly, anal region, and flanks blackish 

 very slightly sprinkled with pale greyish. Mantle chocolate 

 (type) or between cinnamon and russet (paratype), these 

 colours gradually darkening on sides of neck and fore- 

 neck to dark chocolate (type) or russet (paratype). Crown
