2. Vampyrops helleri. 



Vampyi'ops helleri, Peters, MB. Akad. Berl. 1866, p. 392. 



The following is a translation of Dr. Peters's description of this 

 species, of which I have not yet had an opportunity of examining 

 a specimen : — 



Smaller than V. lineatus, Geoffr., but very like that species. The 

 ears are rounded, emarginate externally, and furnished with a 

 rounded lobe at the base ; tragus triangular, pointed, thickened on 

 the inner margin, on the outer thin edge obtusely serrately toothed, 

 and at the base provided with an almost two-lobed process. The 

 horseshoe is free on the edge, each side above thickened, projecting 

 outwards. The lancet is pointed with a broad, also lancet- 

 shaped longitudinal raised ridge. The upper lip is finely notched ; 

 the under lip has, in the middle, a large transverse wart between 

 two smaller warts, and near them seven warts in a line, which, 

 with the corresponding row of the opposite side, form an obtuse 

 angle. 



"Wings from the base of the toes. Interfemoral membrane hairy 

 on the margin. The hair of the body extends outwards as far as 

 the middle of the forearm, and on the upper surface of the tibia, so 

 that as far as a line drawn from the proximal half of the tibia to 

 the elbow the wing-membrane is covered with hair. Brown, with 

 four white longitudinal bands on the head, and a sjdnal line of the 

 same colour as in Y. lineatus. 



Length, head and body about 2"-6, head 0"'8, ear 0"-68, tragus 

 0"-2, nose-leaf 0"-4, forearm l"-4, thumb 0"-45 ; third finger— 

 metacarp. l"-45, 1st ph. 0"-5, 2nd ph. 0"-88, 3rd ph. 0"-6; fourth 

 finger — metacarp. 1"'45, 1st ph. 0"'4B, 2nd ph. 0"'55 ; fifth finger. 

 — metacarp. l"-46, 1st ph. 0"-36, 2nd ph. 0"-4 ; tibia 0"-36, calca- 

 neum 0"'15, interfemoral membrane in the middle 0"-23. 



JIab. Mexico. 



The describer remarks that of this species he had examined 

 two perfectly similar examples which Dr. HeUer had collected in 

 Mexico. 



3. Vampyrops vittatus. 

 Artibeus vittatus, Peters, MB. Akad. Berl. 1859, p. 225. 



Of the size and appearance of small specimens of Artibeus 

 ■planirostris, but at once distinguished by the generic characters 

 of a much longer and narrower muzzle and a difiierently shaped 

 tragus. 



The distance from the eye to the extremity of the muzzle is very 

 nearly equal to the distance between the eyes; the horseshoe is 

 broader and less developed in front than in A. planirostris, but its 

 margin is also free aU round and slightly raised from the muzzle ; 

 the length of the ear, anteriorly, is exactly equal to the distance of
