a " specific name ") but Peters, who edited his paper, decided that it 

 was " Ves^erugo imbricatus, Horsf.," by which he meant tralatitius 

 abramus, and under this name Hutton's notes appear.* More 

 recent collectors have found the species at various localities through- 

 out Northern India, but I can find no published name which 

 appears to be referable to it. 



Pipistrellus paterculus, sp. n. 



A small species with a long os penis as in P. abramus. 



Size about as in P. coromandra. Ears about as in that species ; 

 tragus medium, its inner edge straight or slightly concave, outer 

 slightly convex. Fur rather short, hairs on shoulder barely attain- 

 ing 4 mm.; those on lower back about the same. Colour above 

 sepia brown, the tips of the hairs considerably lighter than their 

 proximal four-fifths ; undersurface brown washed with drab. (One 

 specimen out of six is in a somewhat tawny phase.) Wings to the 

 base of the fifth toe. A well-developed post-calcarial lobule. 

 Penis very large, as large proportionally as in P. abramus, and 

 provided with a bone upwards of 9 m.m. in length. This bone, 

 unlike that of P. abrainus, is practically straight ; it is thickened 

 at the base, where there is a grooved surface for attachment, 

 while terminally it is provided with a pair of well-developed 

 prongs turned down at an angle of 45 degrees to the shaft, each 

 prong so bent in at its tip towards its fellow as nearly to 

 complete a ring. No other species of Pipistrellus has so large an 

 OS penis with the exception of P. abramus, and in that the bone 

 has a peculiar double curve, and its terminal prongs are far less 

 developed. 



Skull without special characteristics, smaller than that of P. tra- 

 latitius, larger than in coromand/ra. Brain-case rather variable in size. 

 Basial pits shallow and inconspicuous. 



Inner upper incisor rather short, with well developed secondary 

 cusp (absent in one specimen); outer incisor rather shorter than the 

 secondary cusp of the inner incisor, its area rather less than that of 

 i\ p* separated from the canine, the fairly developed p\ which 

 about equals i^ in area, half internal, well visible externally. Lower 

 premolars subequal in area, the point of the posterior directed more 

 inwards than that of the anterior. 



Dimensions of the type, the italicized measurements taken in 

 the flesh : — 



Forearm 30 (largest specimen 31-5). 



Read and body 45 mm.; tail 33 ; ear 10*3. Third finger, meta- 

 carpus 28, first phalanx 10.7. Tibia 10.5. Foot 5.8. 



Skull, greatest length 12-3, mesial length 10.1 ; condj^le to front 

 of canine 11.2; zygomatic breadth 7'8; constriction 3*3; breadth
