372 MR. G. E. DOBSON ON THE GENUS ScoTopHILus. [May 4, 
the first premolar is less crushed in between the canine and second 
premolar than in any other species of the genus; it is, however, 
similarly flattened from before backwards, and has two short cusps 
arising internally from the cingulum, which are not found in the 
other species. 
Se. greyti (included in synopsis above) has been named but not 
described. I therefore add a description of this species (the smallest 
of the genus known), taken from an examination of the types in the 
British Museum, and from a specimen of an adult male, preserved 
in aleohol, from Port Essington in North Australia, presented by 
the Earl of Derby to the National Collection. 
ScoToPHILUS GREYII. 
Scotophilus greyii, Gray, List of the Specimens of Mammalia in 
the British Museum, 1843 (not described); Voy. ‘ Erebus’ ‘and 
‘ Terror, 1844, pl. 20 (not described). 
Crown of the head slightly elevated above the face-line; muzzle 
flat above, rather broad, glandular prominences on the sides of the 
face moderately developed: ears short, triangular, shortly rounded 
off above; basal lobe of inner margin rounded, ascending portion 
slightly convex, emarginate opposite the base of the tragus, and 
terminating in a distinct rounded lobe. Tragus broad, obtuse, with 
a triangular lobule near the base; inner margin straight, outer 
straight below, sloping inwards above from a point opposite the 
middle of the inner margin. 
Wings to the base of the toes; postcaleaneal lobe small, but 
distinct, rounded, placed on the caleaneum at a distance from the 
ankle equal to the breadth of the foot ; last caudal vertebra free. 
Above chestnut-brown throughout; beneath similar, the extreme 
points of the hairs ashy. 
Upper incisors close to base of canines, inclined forwards and 
inwards; lower incisors not crowded, indistinctly lobed; lower 
canines without internal basal cusp; first lower premolar small 
and blunt, crushed in between the canine and second premolar and 
pushed slightly inwards; posterior upper molar equal to half ante- 
penultimate molar. 
Length: head and body 1'7, tail 1'*3, ear 0'5, forearm 1°38, 
tibia 0:5, foot and claws 0'°35. 
The following description of a new genus and species has been 
taken from a specimen preserved in alcohol, which had been ob- 
tained in the Bellary Hills, Southern India, by the Hon. J. Dormer, 
and presented by him to the British Museum, 
Scotozous, nov. gen, 
General characters those of Vesperugo, Keys. & Blas., but with two 
incisors only in the upper jaw.
