to the group in which the anterior upper premolar stands in the tooth- 
row, between the second premolar and the canine. The color as 
described by Dobson — “sulphur-brown above, beneath canary 
colour” —he considers perhaps due to faulty preservation. The 
type locality is Kordofan. 
Four skins and eleven alcoholics from Abu Zor on the Blue Nile 
agree structurally in all particulars with dobsoni and undoubtedly are 
referable to that species. The slight narrowing of the vertical process 
of the sella at its middle and the high blunt tip of the connecting 
process are characteristic. The forearm measurement of the type is 
given as 44 mm., and in our series varies between 42 and 44.5 mm, 
The color is a smoky or smoky drab above and clear drab below, so 
that the yellowish tint observed by Dobson is doubtless, as Mr. 
Thomas suggests, a result of poor preservation. As no cranial 
measurements are published, the following are appended: — skull, 
(14,471 M. C. Z.) greatest length 18 mm.; palatal length 6; zygomatic 
breadth 9.5; mastoid breadth 9; upper tooth row to front of canine 
' 6.8; lower tooth row to front of canine 7. 
All our specimens were from a single large colony that inhabited 
the dark interior of a hollow baobab tree. A huge limb had broken 
off making a hole about two feet in diameter by means of which access 
was gained to the interior. The hollow trunk was about ten feet in 
diameter and the main colony of bats was resting in the upper part of 
its dark interior. Many, disturbed by my presence flew around and 
around within the great cavity but did not attempt to pass out into 
the daylight. A faint chippering note was frequently given as they 
flew about. All but three of the fifteen preserved proved -to be females. 
The British Museum has a specimen of Rhinolophus hipposideros 
minimus from Sennar, but we did not meet with the species (Andersen, 
Ann. mag. nat. hist., 1904, ser. 7, 14, p. 455). 
RHINOLOPHUS ACROTIS Heuglin. 
Sharp-eared Leaf-nosed Bat. 
Rhinolophus acrotis Heuglin, Nova acta Acad. Leop. Carol., 1861, 29, art. 15,

At Magangani, about ten miles below Roseires on the Blue Nile, a 
solitary leaf-nosed bat was found hanging inside a hollow baobab tree. 
It was a male and apparently represents Heuglin’s species, the type
