Genus LONCHOPHYLLA Thomas 

 The striking external resemblance of Lonchophylla to Glossophaga 

 has been pointed out in remarks on that genus. The skull is longer 

 and easily distinguishable from that of Glossophaga, by the incom- 

 plete zygomatic arch, and the differing form of the incisors, the upper 

 median pair being relatively narrower, higher and more projecting 

 forward, and the lower series having trifid cutting edges. The teeth 

 are 34 in number. Two species inhabit the region under review. 



LONCHOPHYLLA ROBUSTA Miller 



Rusty Long-tongued Bat 



[Plate 37, figs. 5, 50] 



Lonchophylla robusta Miller, Proc. U. S. Nat. Mus., Vol. 42, No. 1882, p. 23, 

 March 6, 1912. Type from cave on Chilibrillo River, Panama. 



The rusty color and large size distinguish Lonchophylla robusta 

 from the other Glossophagine bats known to inhabit Panama. The 

 forearm measures about 45 millimeters.

 No. 179847, U. S. Nat. Mus. About nat. size. 



The species was first collected by August Busck in a cave on the 

 Chilibrillo River near Alhajuela, in 191 1. In the following year 

 specimens were obtained by me in a limestone cave at about 2,000 

 feet altitude on the slope of the Pirre Mountains near Cana. The 

 same cave was inhabited by Lonchophylla concava, Glossophaga 

 soricina leachii, Hemiderma perspicillatum aztecum, Hemiderma 

 castaneum and Desmodus rotundus murinus. 



Lonchophylla robusta approaches the much smaller species L. mor- 

 dax Thomas in the more important cranial and dental details and 

 departs widely from its large congener L. hesperia. G. M. Allen. No 

 close comparison with L. concava, the only other species of the 

 genus known to occur in Panama, is necessary. 



Specimens examined : Cana, 6 ; Chilibrillo River (Chilibrillo cave 

 near Alhajuela), 4 (including type).
