Ear-conoh as in typical specimens of V. abramus, but the tragus 

 is more narrowed above, slightly smaller, and the lobule near the 

 base of its outer margin is less distinct. The head is also distinctly 

 broader, and more elevated above the face-line, and this breadth of 

 the head causes the muzzle to appear triangular; the glandular 

 prominences are well developed, but occupy chiefly the sides of the 

 muzzle and the upper lip, which is considerably thickened, and do not 

 cause a depression on the upper surface. 



Thumb and feet considerably larger than in V. ahramns ; post- 

 calcaneal lobe narrower and longer, commencing close to the feet. 



Incisors as in typical specimens of F. abramus, but the first 

 upper premolar is longer, and placed quite internal to the canine, so 

 that, although the second premolar is separated from the canine by 

 a small space, the first premolar can scarcely be seen from without.

"The fur is somewhat scanty; it is thickest on tbe back, where it is of an 

 obscure dirty grey, blending in some individuals to a brownish colour, that in 

 front being thinner and of a lighter hue. The main bulk of the fur is of a 

 dark plumbeous, the above-mentioned colours constituting the tips only. 



" Tipper Jaw. — The incisors, both central and lateral, unicuspid and of equal 

 length ; the canines moderately developed ; the first premolar is very small, 

 wedged in between the canine and the second premolar, which is large, as in 

 other species of Scotophilus ( Vesperugo) ; the molars as usual, 



" Lower Jaw. — The incisors and canines not peculiar; the premolars two in 

 number ; the first is small and is unicuspid, the second larger with an obscure 

 basal cusp. The skidl is eminently Scotophiloid, being flat and broad.

" This Bat resembles the S.pipistrellus of Eiu-ope in the contour of the head, 

 the shape of the ear and tragus, the smalhiess and shape of the thumb and nail, 

 the character of the interfemoral membrane, and in the style of colouring. 

 The greater part of the fur in both is of dark plumbeous, the tip alone being of 

 a hue at variance with it. These tips in S. hesperus are brownish grey and 

 fawn, in S. pipistrellus being a rich olive-brown." 



The above desci-iption agrees very well with a specimen of a Bat from the 

 Straits of Juan da Fuca (Vancouver's Island), which is preserved in the collec- 

 tion of the Haslar Museum near Portsmouth, and whicli appears to me to be 

 identical with V. abramus ; but I hesitate to accord to the latter species so wide 

 a distribution on the evidence of a single species, though it is highly probable 

 that, as the Serotine is found also in America, tliis species, which has so wide a 

 distribution in the eastern hemisphere, may also extend into the New World,
