500 On a new Genus of Free-fad Baf. 



mcetin*^ in the middle line, rromaxillaiy notch narrow, not 

 expanded behind. Mesopterygoid fossa without median bony 

 ridge. Ramus of lower jaw very low vertically. 



Incisors ^; the i;pper pair long-, nearly parallel, bicuspid, 

 the lower ones subequal, all bicuspid. No trace of a small 

 upper premolar, though the large p^ does not touch the 

 canine. 



Type Platymops ]\[a.cmiUanK 



Tliis most remarkable bat is readily distinguishable from 

 any member of the jXt/ctinomus group by its extraordinarily 

 ilattened head, unusual digital pioportions, shortened wing-:, 

 and dental formula. In this group it has a curious analogy 

 with the Vespertilionine genus MimpJillufi^ being modified in 

 its proportions and the shape of its head almost exactly in 

 the same way, and having a strong superficial resemblance 

 to it. 



Platymops Macmillani, sp. n. 



Size about as in Mormopterus acetnbulosns, the abnormally 

 short forearms giving a deceptive idea of the general bulk. 

 Fur short; hairs of back about 3 mm. in length. General 

 colour above smoky bhickisli, below dull whitish along the 

 middle area, blackish along the sitles. Limbs dark above, 

 whitish below ; mombraues dark tiiroughout, except that the 

 surface near the body below is lighter, as is the extreme edge 

 of the plagiopatagium. Ears widely separated, triangular, 

 their anterior edge evenly convex, their tip rounded; anti- 

 tragal notch scarcely perceptible. Tragus fairly large, 

 quadrate, its inner edge about equal to its breadth at tip. 

 Upper side of forearm, wrist, and basal half of third meta- 

 carpal thickly and coarsely shagreened with small round 

 warts, very much as is the case in Vespertilio Floweri, 

 de Wint. V/ing-membrane attached to tlie distal third of 

 the tibia. Upper side of the short lower leg flattened, finely 

 granulated. Proximal planlar pad very prominent. Penis 

 short, without special modifications. 



8kull and teeth as described above.
