Show 372 MR. G. E. DOBSON ON THE GENUS SCOTOPHILUS. [May 4, the first premolar is less crushed in between the canine and 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. Sc. greyii (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 alcohol, 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; postcalcaneal lobe small, but distinct, rounded, placed on the calcaneum 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 antepenultimate 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 obtained 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. & Bias., but with two incisors only in the upper jaw.
