5. ScotopMlus rueppellii. 



Nycticejus riippellii, Peters, MB. Akad. Berl. 1866, p. 18. 

 Scotophilus i-ueppollii, Bobson, P. Z, S. 1875, p. 371. 



Ears about the same length as in Sc. temminckii ; the internal 

 basal lobe short, rounded ; lower half of the inner margin of the ear 

 regularly convex, upper half straight ; tip obtusely rounded, outer 

 margin commencing abruptly by a small concavity beneath the tip, 

 causing it to project slightly outwards, then slightly convex down- 

 wards, emarginate opposite the base of the tragus, and terminating 

 in a convex lobe. Tragus shorter, subacutely pointed, and less 

 curved inwards and forwards than in Sc. temmincJcii, the lobule at 

 the base of the outer margin succeeded by a shallow emargination, 

 terminated above, slightly below the middle of the outer margin, by 

 a prominent tooth, above which the margin becomes slightly convex ; 

 inner margin straight, below, slightly concave in upper third ; no 

 transverse ridge on the outer surface of the tragus (Plate XV. 

 fig. 2). 



Pur similar in distribution to that of Sc. temmincJcii, but some- 

 what longer and of a darker shade. Some specimens are very dark 

 brown above, the extreme tips slightly ashy ; beneath dark brown, 

 the terminal one fourth of the hairs ashy. In others the fur has a 

 chestnut tinge throughout. 



The cingulum of each upper incisor develops a minute cusp 

 posteriorly and externally. The lower incisors are more crowded 

 between the canines than in Sc. temminckii, forming by their 

 arrangement an acute angle. 



Length (of an old $ with worn teeth), head and body 2"-8, tail 

 l"-9, head 0"-9, ear 0"-7, tragus 0"-3, forearm 2", thumb 0"-4, third 

 finger 3"-5, fifth finger 2"-25, foot 0"-48.

Scotophilus greyii, Graij, List of the Specimens of Mammalia in the 

 British Museum, 1843 (not described) ; Voy. ' Erebus' and ' Terror,' 

 1844, pi. 20 (not described) ; Bobson, P. Z. S. 1875, p. 372. 



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 (Plate XV. fig. 4). 



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.
