Show 1882. ] FROM THE CAROLINE ISLANDS. 757 woolly; above, it grows thinly along the humerus and half the forearm, and thickly over the whole of the interfemoral membrane, and down the tibiae nearly to the ankles. Beneath, the proximal halves of the humeri are covered ; there are a few hairs behind the elbow and on the proximal third of the interfemoral. The fur along the back is nearly two inches in breadth. Ears very short and almost buried in the fur, both edges evenly convex, the outer more strongly so than the inner; tip sharply pointed. Wings arising within half an inch of each other on the back. Interfemoral membrane very narrow in the centre, quite bidden by the fur. Teeth (Plate LV.) smaller even than in Pt. phaocephalus. Canines with much narrower postero-internal ledges. Above, the first premolar is either absent, or, if present, stands quite outside the tooth-row ; last molar about the same size as one of the outer incisors. Below, the first premolar is slightly larger than the penultimate molar, the latter, like the other molars, being remarkably small. Last molar about equal to one of the outer incisors. The following are the dimensions of three specimens of this species. The first is the specimen described; the other two, however, only differ from it in being of a somewhat darker colour throughout and in having slightly longer ears. a. b. c. Mortlock I.
