Neotropical Bats of the Genus Eptesicus. 361 



America in the form known a3 E.f, miradorensis , but I am 

 now able to record its presence as far into S. America as 

 ]\Iori(ln, Venezuela, whence comes a bat wliicli I may com- 

 mence by describing. 



Eptesicus fxiscus pelUceus, subsp. n. 



General characters very much as in E. f. miradorensis^ 

 All., of Mexico and Ccntial America, but fur decidedly longer.. 

 Colour quite as iu Guatemalan miradorensis, the dorsal hairs 

 blackish for four-fifths tiieir length, theirends glossy cinnamon; 

 underneath paler, the ends dull buffy whitish. Hairs of back 

 about mm. in length. 



Skull about as in miradorensis. 



Dimensions of the type (measured on skin) : — 



Forearm 54 mm. 



Third tinger, metacarpus 50, first phalanx 19'5. 



Skull : palato-siuual length 8"6 ; interorbital breadth 4'3 ; 

 front of canine to back of «t' 7"5 ; front of ^* to back of ni^ b"l. 



Hah. Heights near Merida, Venezuela. Type from La 

 Culata. Air. 4000 m. 



Type. Old female. B.M. no. 98. 7. 1. 28. Collected 

 20th June, 1897, by S. Briceiio. One specimen only. 



Turning now to the true lightly built S. -American species^ 

 there is a considerably larger number of names to be reckoned 

 with than has hitherto appe:ired, as I find no less than fourteen 

 described from ditfrrent parts of the continent, some of these 

 having been wholly neglected by modern writers. Indeed, 

 the earliest one of all, hrasiliensis, Desm., 1819, seems never 

 to have been uted, hut should evidently supersede hilarii, 

 I. Geoffr., 1824, for the comparatively large dark-coloured 

 Biazilian S])ecies, with which it is probable that derasns^ 

 Burm., 1854, arctoides and nitens, Wagn., 1855, and arge, 

 Cope, 1889, are all synonymous. Then it seems evident that 

 dorianns, Dobs., 1S85 (^lisiones), is synonymous with furi- 

 nu//s, D'Orb., 1847 (CorrientesJ, with ft)rearm* 37-38 mm., 

 wliilc tor the pale Ecuadorean and N. Peruvian coast-species 

 I tear that iiinoxius, Gerv., 1841 (Amotaiie, Piura), will have 

 to supersede csjkhUv, Cabrera, 1901 (Babahoyo). E. melauo- 

 ptei'us, Jent., 1904, would be the name lor the Guianan species 

 (forearm 37—10 nnn.), to which chapmani, Allen, 1915, is 

 likely to be nearly related. Then andinus, Allen, 1915, 

 would be the highly suitable name lor a dark-coloured species 

 which ranges down the Aiuban chain frmn N. Cvdombia to 

 Peru, our most southern examples coming from Chanchamayo.
