with well-developed W-shaped cusps, the last molar half the antero- 

 posterior diameter of the antepenultimate molar ; the two lower in- 

 cisors small, with broad straight cutting-edges ; first lower premolar 

 equal to or exceeding the second in cross section at the base, but less 

 than it in vertical extent. Premolars and molars in both jaws 

 very close together, their vertical extent in relation to their antero- 

 posterior diameter at the base much greater than in Phyllostoma 

 hastatwn.

This species is easily distinguished from all other known species 

 of Phyllostomidse by the peculiar toothed and crenulated condition 

 of the margins of the erect nose-leaf. 



In the mouth and throat of a specimen preserved in alcohol, in 

 the Collection, I found portions of some small Coleopterous insects.

Ears large, as in T. crenuliitmn, more rounded oif above ; nose-leaf 

 similar in size, but the margin of the lancet-shaped portion is entire 

 from the tip downwards as far as a small emargination immediately 

 above its base, beneath which a tooth-like process occiirs, on the pos- 

 terior side of which the posterior margin of the horseshoe-shaped 

 membrane is fastened ; the central longitudinal ridge of the lancet 

 is much developed ; on either side at its base, at the inner margins 

 of the nasal apertures, valve-like covering processes occur; horse- 

 shoe-shaped membrane as in T. crenulatum ; lower lip with a large 

 wart in the centre of a V-shaped double row of small transverse 

 warts. 



Wing-membrane from the metatarsus ; calcaneum slightly longer 

 than the tibia. 



The hair of the body extends sparingly for a short distance only 

 on the membranes, the proximal half of the humerus is clothed ; the 

 forearm, femur, and tibia are naked. Above, dark brown, with a 

 pale-coloured spinal line ; beneath, dirty yellow, the under surface 

 of the jaws and sides of the neck bright reddish yellow. 



Hab. Brazil (Mato Grosso). 



The above description is taken from Dr. Peters's notes on the 

 single type specimen preserved in the Vienna Museum, which I have 

 not yet seen. 



The following are the measurements of this species and of 

 T. crenulatum : —
