PIPISTRELLUS EUEPPELLI.

ill-defined. All these specimens have the simple upper incisor of the typical P. kiihli, 
and all their measurements agree with those distinctive of the species. 
I have compared the type of V. marginatus, Cretzschmar, preserved in the Frankfort 
Museum, with these specimens, and I find it agrees with them in all its structural 
features. In the text of RilppeH’s ‘ Atlas,’ it is stated that the type came from Arabia 
Petrsea ; but on the specimen itself, Egypt is given as the locality. 
Dobson has referred the Vespertilio pipistrellus of E. Geoffiroy St.-Hilaire to 
Vesperugo pipistrellm (= Pipistrellus pipistrellus), but 1 think it will more probably 
prove to belong to the species under notice; and since making this identification, 1 
have observed that Lataste ^ had arrived at a similar conclusion in 1885. Geoffroy 
regarded it as a variety of the common Pipistrelle of France, with the same figure 
and proportions, but differing from it in the pelage being of an ashy colour, whereas 
the European bat is brown.

Forehead raised above the facial portion of the skull. Glandular eminences on 
muzzle well-developed; the breadth of the face at the anterior angle of the eye is 
one-fourth more than the interval between the outer angle of the eye and the tip of 
the snout. The ears when laid forward reach to near the nostrils, and are more or less 
triangular in form, but rounded at their tips. Inner portion of conch very slightly, 
if at all, convex below the rounding off of the tip, but markedly convex at its basal 
bend backwards; outer border of conch slightly convex, terminating slightly behind 
the eye and somewhat below the level of the mouth, the notch above the lobe of the
