In one of the specimens the occipital ridges are higher and 
blunter than in the one described. In a Balabac specimen, which 
is about half grown, the low ridge following the canthus ros- 
tralis and that between the eyes form a distinct angle at the 
anterior corner of the eye and then a second angle is formed 
at the union of the occipital ridge with the interorbital ridge; 
the connection between the supratympanic ridge and the occip- 
ital ridge behind the eye is very indistinct; the parotoid gland 
is as long as its distance to the anterior corner of the eye. The 
specimen is a male, showing the internal openings to the vocal 
sacs. There is a rather distinct skin fold from the parotoid back 
toward the groin, surmounted by rather large tubercles, which 
is only dimly evident in the specimen described, where the 
markings are indistinct, and the limbs dimly barred. 
A young specimen from northern Palawan (42 millimeters) 
has distinct markings, but the cranial ridges are dim or wanting. 
As shown by my specimens, the cranial ridges are variable in 
arrangement and distinctness and the relative length of limb 
and body varies. 
Specimens collected by myself were found along streams in 
the low mountains of northern Palawan and Busuanga, during 
rain storms. The type was collected at Puerto Princesa in 
Palawan by A. Everett. 
PELOBATID^ 
Upper jaw toothed; vomerine teeth frequently present; diapo- 
physes of sacral vertebrse strongly dilated; terminal phalanges 
simple; vertebrse procoelous or opisthocoelous ; pupil vertical. 
The family is widely distributed, but has comparatively few 
species. It is found in Europe, India, Malasia, and central North 
America. Only one genus, Megalophrys, has been recognized in 
the Philippine fauna.
