2. Chilonycteris personata. 



Chilonycteris personata, Wagner, Wiegm. Archiv, 1843, p. 367 ; 

 id. Suppl. Sehreb. Sdugeth. v. p. 680 (1855); Burrmister, Thiere 

 Brasiliens, p. 76 (1854) ; Peters, MB. Akad. Berl. 1872, p. 360. 



Slightly larger than the preceding species, and distinguished from 

 it by the absence of the small cutaneous projections from the upper 

 margins of the nostrils and by the less abrupt elevation of the outer 

 margin of the ear-oonch at the junction of its upper third with its 

 lower two thirds, which forms hero a right-angled notch. 



According to Wagner and Burmeister, it resembles Oh. davyi (see 

 p. 453) in all respects except in the attachment of the wing-mem- 

 brane and nakedness of the back. 



Pur above dark brown, beneath paler, the extremities of the hairs 

 much paler on both surfaces. 



Length, head and body 2"-l, tail 0""7, ear 0"'6, forearm l"-75. 



Hah. Guatemala ; Venezuela ; Brazil (Mato Grosso). 



The type of this species, which I have not yet seen, is preserved 

 in the Vienna Museum, and the above description is taken from 

 Wagner and Burmeister. 



3. Chilonycteris psilotis. 



Resembles Ch. madeayi closely in size, hxit easily distinguished 

 by the absence of the notch on the outer side of the ear and of the 

 small projections from the upper margins of the nostrils, as well as 

 by the colour of the fur and by the different proportions of the 

 bones of the extremities. 



The inner margin of the ear-conch is quite similar to that of Ch. 

 madeayi, but, at the termination of the emargination which occu- 

 pies the upper half of the outer side, and is much shallower than in 

 that species, instead of an abrupt elevation forming an acute-angled 

 notch, the margin becomes very gradually convex, almost straight 

 (Plate XXIII. fig. 2, ear, enlarged). 



The small projection on the upper surface of the muzzle, expanded 

 lower lip, and horizontal cutaneous process from the chin as in Ch. 

 madeayi, with which it also agrees in dentition. 



Fur orange above and beneath, with orange-brown extremities ; 

 darker above, paler beneath. 



Length, head and body l"-7, tail 0"-7, head 0"-65, ear 0"-65 x 0"-3, 

 tragus 0"-2, forearm l"-65, thumb 0"-25 ; third finger— metacarp. 

 l"-5, 1st ph. 0"-28, 2nd ph. 0"-5, 3rd ph. 0"-55 ; fourth finger— 

 metacarp. l"-3, 1st ph. 0"-3, 2nd ph. 0"-35 ; fifth finger— metacarp. 

 1"-15, 1st ph. 0"-38, 2nd ph. 0"-35 ; tibia 0"-6, foot 0"-4.
