12. VESPEKTILIO. 325 



front of the base of the tragus in a very distinct small thickened 

 lobe ; tragus long, attenuated, and acutely pointed, outer margin 

 slightly concave above, inner margin correspondingly convex, so that 

 the tragus inclines outwards (Plate XIX. fig. 10, ear, enlarged). 



Feet large ; wings from the base of the toes ; calcaneum short, the 

 last caudal vertebra free. 



Above black, the hairs with light brownish-yellow extremities ; 

 beneath dark at the base, the terminal one fourth of the hairs yel- 

 lowish white. 



Above and beneath the fur of the body extends upon the wing- 

 membranes nearly as far as a line drawn from the middle of the 

 humerus to the knee-joint ; above, the base of the interfemoral only 

 is covered ; beneath, a few fine hairs appear on the proximal half 

 chiefly along the tail. 



Teeth as in V. mystacinus. 



Length, head and body l"-7, tail l"-4, head 0"-6, ear 0"-65, tragus 

 0"-33, forearm l"-35, thumb 0"-3, third finger 2"-2, fifth finger l"-8, 

 tibia 0"-6, foot 0"-35. 



Other specimens vary in being slightly larger or slightly smaller. 



Sab. North (and probably Central) AJnerica ; according to Allen, 

 not found west of the Rocky Mountains. 



This species approaches V. mystacinus, but not so closely as V. 

 nitidus. The ears are larger, and the outer margin of the ear-conch 

 not deeply emarginate above ; the feet are also larger, and the last 

 caudal vertebra is free.

40. VespertiUo carolii. 



Vespertilio carolii, Temminck, Monoyr. Mammal, ii. p, 237 (1835-41). 



Head scarcely elevated above the face-line ; glandular promi- 

 nences between the eyes and nostrils rather more developed upwards 

 than in most species of the genus, resembling in this respect V. 

 levis ; they do not add to the breadth of the muzzle, nor cause a 

 concavity between them on the face ; extremity of the muzzle pro- 

 jecting slightly beyond the lower lip in front. Ears somewhat 

 shorter than the head ; laid forwards the tips extend exactly as far 

 as the end of the nose ; the internal basal lobe acute in front, the 

 horizontal margin joining the ascending margin slightly under a 

 right angle ; the inner margin of the ear regularly convex from the 

 base upwards, except quite near the tip, where it is straight ; tip 

 obtusely rounded off, projecting slightly outwards ; beneath the tip 

 .nearly half the outer margin is slightly concave, then convex, 

 distinctly concave opposite the base of the tragus, and terminating 

 in a small convex lobe. The shape of the ear is similar to that of 

 V. mystacinus, but the lower half of the outer margin is less con- 

 vex. Tragus narrow, attenuated in its upper third, which inclines
