Type.—No. 1638, Bureau of Science collection; collected near 
the southern end of Tawitawi Island, P. I., October, 1918, by 
E. H. Taylor. 
Description of type.—(Female.) Vomerine teeth in two short, 
obliquely placed series between choanz, separated from the latter 
by a distance half their length, and from each other by a distance 
nearly equal to their length; choanz large, distinct, distance 
between them greater than distance from eye to nostril; distance 
between Eustachian tubes equals their distance from nostril; 
head rather flat, longer than broad, very slightly depressed on 
middle part of snout; canthus rostralis angular; loreal region 
nearly vertical, somewhat concave; snout rounded when viewed 
from above, rather pointed when viewed laterally, projecting; 
nostril much nearer end of snout than eye; distance between 
nostrils equals their distance from eye, as well as the interorbital 
- distance and width of upper eyelid; diameter of eye reaches 
beyond nostril; diameter of tympanum from two-thirds to three- 
fourths that of eye; tympanum very distinct; skin above smooth 
or minutely granular; no dorsolateral glandular folds; no supra- 
tympanic folds; no fold or a very indistinct one above insertion 
of forearm; skin on sides with occasional, rather large tubercles; 
limbs smooth above and below; belly, chin, and throat entirely 
smooth; anal region strongly granular; limbs slender; first finger 
very slightly longer than second, both a little shorter than fourth; 
fingers with small disks, rather pointed in front; subarticular 
tubercles distinct; three distinct carpal tubercles, the largest at 
base of first finger; toes slender, long, the disks larger than the 
finger disks, tips somewhat pointed; toes scarcely more than 
half webbed; the membrane reaches second subarticular tubercle 
on fourth toe; fifth longer than third, reaching midway between 
first and second subarticular tubercles; a small inner metatarsal 
tubercle equal to about one-fourth the length of first toe, and 
a distinct outer metatarsal tubercle; subarticular tubercles of 
toes well developed; a very slight fold from tip of fifth toe to 
tibia; males with well-developed internal vocal sacs; tibiotarsal 
articulation reaches nostril.
