Skull: greatest length, 28 ; basal length, 24.8 ; palatal length, 16 ; interorbital 

 constriction, 4-7; breadth outside first molar, 5.6 ; mastoid breadth, 10 ; greatest 

 breadth of brain case, 9.5 ; mandible, 20.3 ; maxillary tooth row (exclusive of in- 

 cisors), 9; mandibular tooth row (exclusive of incisors), 9.4. 



Remarks. — I am indebted to Professor A. E. Verrill, of Yale University, for 

 the privilege of describing this species. The original lot contained three speci- 

 mens, all from Zorritos, and one of these, the type, has been presented to the 

 Museum of Comparative Zoology ; the two others are in the Peabody Museum at 

 Yale. The type is slightly the smallest of the three ; the forearms of the two 

 others measure 39.6 and 40.6 mm. respectively. The forearm of L. mordax, de- 

 scribed by Thomas from Bahia, Brazil, is given as 34 mm., " all the specimens 

 about the same," and the other measurements are correspondingly smaller in the 

 eastern animal (3d digit, metacarpal, 31; 1st phalanx, 11.3; 5th digit, meta- 

 carpal, 29 ; 1st phalanx, 8.5 ; greatest length of skull, 23.7). It is not unlikely 

 that further research will discover intergrades from the region between Peru and 

 the Brazilian coast ; but in the absence of these, the Peruvian bat may for the 

 present stand as a full species. Additional measurements of the two other 

 specimens at the Peabody Museum, New Haven, follow (original numbers are 

 illegible) : 



MEASUREMENTS OF . LONCHOPHYLLA HESPERIA. 



The tongue of the second specimen projects 21 mm. beyond the nose. 



Anoura geoflroyi Gray. 



A small series of adults and young was collected at Texolo, Vera Cruz, Mexico, 

 on March 15, 1899. 



Lonchoglossa caudifera E. Geoffroy. 



A series of five alcoholic females from Rio Janeiro, Brazil, shows an interest- 

 ing variation in the development of the rudimentary tail. In Nos. 4000 and 

 4001 it distinctly projects just beyond the free border of the uropatagium, and 

 consists in the former of four vertebrae (outside the body), the terminal one 

 of which is much shorter than the others, and whose combined length is 4 mm. 

 In No. 4006 the tail is about 3.5 mm. long outside the body, and only reaches to
