MORMOPS.—MACROTUS. 37 
West-Indian I. blainvillii, Leach ; but may be recognized by the non junction of the 
cutaneous bands which unite the ears with the muzzle, by the chin-leaf being deeply 
indented below, and by the reddish-brown colour of the fur. Its forearm measures 
about 2"°15.

Originally distinguished from its Antillean ally, WZ. blainvillii, by Professor Peters in 
1864, M. megalophylia has since been recorded from Venezuela, Colombia, and various 
parts of Central America. Its habits are doubtless identical with those of M. dlain- 
villit, which is described by Osburn as a Bat of great agility and rapidity of flight, but 
of very delicate constitution. He was unable to keep it lopg in confinement; but 
observed that in drinking “the tongue was protruded, but the water taken up by it 
and by the foliation of the lips was sucked in, with the head raised, by an action very 
like chewing ” *. 
3. MACROTUS. 
Macrotus, Gray, P. Z.8. 1843, p. 21. 
The next six genera of Phyllostomide are included by Mr. Dobson in his group 
Vampyri, which differs from the Mormopes in the nasal leaf surrounding the nostrils 
instead of being placed behind them; and from the Glossophage in the tongue being 
moderate in length and obtuse, and in the lower lip not being cleft above. 
Of these genera Macrotus is further distinguished by its large oblong ears, united at 
the base, and by its long tail, of which one vertebra at least projects beyond the deeply 
concave margin of the interfemoral membrane. Only two species are well established, 
both of which are natives of Central America. ‘These may be characterized as 
follows :— 
1. Ud. waterhousii. Ears longer than head; nose-leaf in front raised above level 
of upper lip; last caudal vertebra only free. Forearm 2!"15. Fur reddish- 
brown, paler beneath.
