232 VESPERTILIONID^. 



elbow to the knee ; fur longer on the ventral than on the dorsal 

 STirface. 



Inner upper incisor on each side very slender, long, and unicus- 

 pidate, the outer incisor very small and_ close to its base; lovrer 

 incisors at right angles to the direction of the jaw ; second upper 

 premolar separated by a narrow space from the canine, through 

 which the summit of the minute first premolar can in some speci- 

 mens be seen. 



Length (of an adult d ), head and body 1""6, tail 1"*5, head 0"-55, 

 ear 0"-5, tragus 0"-22, forearm l"-3, thumb 0"-22, second finger 

 2"-25, fourth finger l"-6, tibia 0"-45, foot 0"-25. 



(Three specimens (from Palma and Madeira) have been examined 

 and measured by me and found to agree in all respects.) 



Hab. Madeira and Canary Isles. 



This species is closely allied to V. Jcuhlii, but may be at once dis- 

 tinguished by the much shorter body and longer tail, by the very 

 deep emargination on the outer side of the ear, and by the complete 

 absence of the white margin to the membranes.

 Vesperugo krefftii, Peters, MB. Ahad. Berl. 1869, p. 404. 



Ears shorter than the bead, laid forwards their extremities do 

 not reach halfway between the eyes and the end of the nose ; ear- 

 conch triangular, inner margin very convex in lower half, the tip 

 rounded off and distinct, owing to a deep and abrupt emargination 

 which occupies the upper third of the outer margin, middle third 

 convex above, then straight, lower third terminating abruptly with- 

 out forming a lobe ; tragus narrow in upper third, acutely pointed 

 and curved inwards, a distinct acutely triangular lobe at the base of 

 the outer margin. 



Wings from the base of the toes or from the metatarsus ; the small 

 cartilaginous extremity of the tail alone free ; postcalcaneal lobe 

 very shallow, as in the Serotine. 



Face in front of the ears nearly naked, glandular prominences 

 with a few long hairs ; wing-membrane naked except along the 

 sides of the body, under surface of the interfemoral with short fine 

 hairs. Above, dark reddish brown, paler beneath ; the base of the 

 hairs on both surfaces very dark brown, almost black. 



Upper outer incisor on each side extremely small, about equal to 

 the cingulum of the inner incisor in vertical extent ; inner incisors 

 unicuspidate, long and strong ; first upper premolar minute, in the 

 inner angle between the canine and the closely approximated 

 second premolar ; lower incisors transverse, placed at right angles 

 to the direction of the jaws ; first lower premolar about one third 

 the vertical extent of the second.
