deflected, though placed at a slight angle with palate. Occipital 
region without trace of tubular elongation. Alveolar line projected 
backward barely touches audital bulla and occipital condyle. Ros- 
trum short (least distance from orbit to nares less than lachrymal 
width), its dorsal profile slightly concave. Premaxillaries in con- 
tact anteriorly, but not fused, slender throughout, and tapering 
above to a recurved point 
distinctly below upper 
rim of nares. Palate nor- 
mal. Audital bullae well 
developed, but without 
tube or lip at meatus. 
Mandible with broad low 
angular process. Exter- 
nal form short and heavy. 
Nostrils very prominent, 
almost tubular. Upper 
lip divided by a deep nar- 
row vertical groove. Sec- 
ond finger with well-de- 
veloped claw. Wings 
from sides of back. Tail 
distinct, its terminal half 
free from the inter femo-

weak, its length about 
equal to breadth of foot.
