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 choan*, separated from the latter 
by a distance half their length, and from each other by a distance 
nearly equal to their length; choanee 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; loreai 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 v/ebbed ; 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.
