220 DR. KNUD ANDERSEN ON BATS. [Apr. 7, 



Specimens examined. — 24 specimens (19 skins) and 23 skulls, 

 from the following localities : — 



British Museum: — Brazil: Pava (1); Egas (Teffe), Amazonas 

 (1).— Peru: Chanchamayo, 1200 and 1500 m. (2).— Ecuador : 

 Sarayacu (1). — Colombia : Cali, 1100 m. (1) ; Onaca, Santa Marta, 

 700 m. (2). — Venezuela : Valencia (1). — Panama : Colon (1) ; 

 Chiriqui (2); islands off Panama: Brava I, (3); Cebago I. (1); 

 Jicaron I. (1); Insoleta (1); Gobernador I. (3). — Costa Bica ; 

 Miravalles, 400-500 m. (1).— 21 skulls, from all the localities 

 enumerated. 



U.S. National Museum*: — Trinidad: Port of Spain (1). — 

 Panama : Colon (1). — Skulls of both specimens. 



Eavige. — From Sao Paulo and Peru, at least as far north as 

 Costa Rica ; unrepresented in the West Indies (Trinidad 

 excepted). 



Pefcers's Urodernia hilohatum, 1866. — The type, in the Berlin 

 Museum, is " ein jiingeres Exemplar aus St. Paulo in Brasilien" ; 

 Peters had also " zwei andere ausgewachsene [Exemplare] aus 

 Cayenne'"' in the Berlin Museum, and "ein mannliches aus- 

 gewachsenes Exemplar in Weingeist " from the Frankfurt 

 Museum without exact locality {cf. Riippell, I. s. c). The whole 

 of the original description and all measurements (there is an 

 obvious error in the measurement of the second phalanx of the 

 fourth digit) precisely agree with the series of specimens here 

 referred to U. hUobatum. — The figures in the plate belonging to 

 Peters's intended Monograph of Bats (Z. s. c.) are excellently 

 drawn and partly well reproduced, but the hind legs in the life- 

 size figure (fig. 1) are much too short, as if drawn from a damaged 

 specimen (with broken legs ?). 



Lyon's Uroderma convexum, 1902. — Type : $ young ad. ; Colon, 

 Panama. Based on two specimens from the type locality. For 

 comparison Lyon had two U. hilohatum from Chapada, Brazil 

 (probably Sao Joao River, Chapada da S. Maria, N. Minas Geraes ; 

 and probably the same specimens as recorded by Cope, 1889, 1, s. c, 

 and by Rehn, 1901, I. s. c). — The characters of U. convexum are 

 summed up, by Lyon, as follows : " Similar to L . hilohatum Peters, 

 but with tooth-rows distinctly arcuate" ("less nearly parallel 

 than those of U. hilohatum "). 



Besides a specimen from Colon in the British Museum (pre- 

 sented by Marquis Doria), nine specimens from islands W. of 

 Panama, two from Chiriqui, and one from Costa Rica, I have had 

 for examination Lyon's paratype, a young adult from Colon. — 

 " U. convexum " is in every respect indistinguishable from U. 

 hilohatum from Brazil, Peru, Ecuador, Colombia, Venezuela, and 

 Trinidad. Li the whole sei'ies of skulls of U. hilohatum examined, 

 23 in number, the upper tooth-i-ows are decidedly arcuate ; by 

 close comparison of the skulls an excessively small variation in the 

 outline of the tooth-rows is, of course, observable, as is also, the 



* U.S. N. M. nos. 22472 (37901), 111721.
