General colour black, the black hairs intermixed with shining white ones, especially on 

 the belly; round the eyes yellow brown hairs, also from eyes to sides of nostrils; round the 

 black ears, back of head, nape, shoulders to base of wings yellow brown, more or less con- 

 tinued anteriorly, forming a ring, more visible in the female than in the maie. Outer margin 

 of the ear feebly concave beneath the obtusely pointed tip. The hairless wings black, the 

 ditto colored small interfemoral membrane concealed in the centre by black hairs. 



Temminck's alecto was based upon a spécimen from Celebes; the type however seems 

 to be lost, as it was not in our collection when I wrote the Catalogue (1888); without the 

 type-specimen however it is very uncertain to understand Temminck's description ; Peters 

 studied the type-specimen and concluded it to be the same species as his chrysauchen. How- 

 ever this question must be solved ; perhaps the best solution is that of Matschie, viz. to 

 call the Celebes-form alecto and the eastern-form chrysauchen. After a deeper study based 

 upon extensive fresh (alcoholic) material, it may perhaps turn out that the named forms, toge- 

 ther with conspicillatus and others, belong to one species; the différences in size, color and 

 dentition indeed are very insignificant. It is very likely that the measurements given by Dob- 

 son (Catalogue, p. 56) of what he called alecto, as well as those from Peters' chrysauchen, hâve 

 been taken from dried skins, therefore I thought it important so give a séries of exact mea- 

 surements and a color-description after good conditioned alcoholic individuals. 



It seems that this species hitherto has been met with on New Guinea only in the 

 neighborhood of Doré and on the Macluer Bay (cf. my paper on the New Guinea Mammals, 

 Notes Leyden Muséum, Dec. 1906, Vol. XXVIII, p. 163). Our adult maie and female are 

 from Mios Korwar (N. W. of Schouten Islands), collected July 18. 1903, by the Humboldt 

 Bay expédition. 



2. Dobsonia paliata Geoffroy. 



Two adult female-specimens from the interior of the Humboldt Bay, collected in May 

 1903 by the Humboldt Bay expédition; one from the Mosso River, the other from the Sen- 

 tani Lake. 



Measurements in millimeters of the two adult female-specimens, preserved in alcohol :
