ON THE GLOSSOPHAGIN®. P55 
The first lower premolar possesses a small, anterior, basal cusp and is, therefore, almost 
as large as the other premolars. The main cusp throughout scarcely higher than the 
basal cusp. 
Anura wiedii Peters. 
Auricle much the same as in Lonchoglossa. The tip of the tragus is pointed. Nose 
leaf simple, acuminate, no depression above nostrils. The gland mass at the side of the 
nostril continuous with that extending up to the side of the nose leaf. Upper lip with 
two equidistant warts. Fur everywhere long and silky. Above, apical third dark brown, 
basal two-thirds Isabella brown. Below, apical third Isabella brown ; basal two-thirds dark 
gray. Thus the arrangement of color is boldly contrasted with that of other forms in the 
group. Fleshy mass of forearm, the interfemoral membrane, the thigh and the feet 
covered with short hair. On the ventral aspect the forearm is covered with fur which 
extends thence a short distance on the interfemoral membrane. 
The proportions of the wing of Anuwra are those of a larger animal than Loncho- 
glossa, though the thumb is of the same size. The lower extremities are almost identi- 
cally the same in size, the calcar alone being larger in Lonchoglossa. The absence of the 
phalanx has already been noted in Chernycteris. Alliance with this genus is suggested 
in the great width of the cleft in the lower lip and in the possession of warts on the 
upper lip. 
The muscle fascicles and membrane markings are as in Glossophaga, but the 
terminal cartilages of the fourth digital interspace while spatulate exhibit the limb on 
the somad side greatly prolonged. This character is not seen elsewhere in the group. 
The cartilage of the fifth digit while terete is also greatly prolonged on the free margin of 
the endopatagium. These characters indicate that there is more strain on the wing 
during flight than in any other genus. . 
The Skull—Vhe skull is almost identical with that of Lonchoglossa. The alveolar 
height is one-third the width of the neck of the canine and one-seventh the vertical dia- 
meter of the anterior nasal aperture. The zygoma by careful maceration is shown to be 
cartilaginous. A specimen of Lonchoglossa shows the same structure. The skull is 
24 mm. long. The brain case is 60 mm. long, and the face 40 mm. The lower border 
of the masseteric impression is not produced. Dobson’s figure, Pl. XX VII, Fig. 4, does 
not agree in all respects with our example. 
In 1830, Rengger (Naturgesch. der Sdugeth. von Paraguay, 80) described a species 
of bat under the name Glossophaga villosa. Since Wagner (Suppl. Schreb. Siugeth.) 
assigns this forma place under Chernycteris, it is well to state that while G. villosa 
Rengger retains three premolars in both jaws, that the tail is absent, the interfemoral]
