Remarks . — This species differs from the two other known 
species in the absence of the secondary row of teeth in the lower 
jaw. I do not think that this fact warrants the making of a 
new genus, since we find that the second series of teeth appears 
to be degenerating, even in Ichthyophis monochrous. A single 
specimen was collected in Palawan by C. M. Weber, I take 
pleasure in naming this species for Mr, Weber, whose untiring 
efforts have greatly enriched the natural-history collections of 
the Bureau of Science. 
RANID^ 
Upper jaw toothed; diapophyses of sacral vertebrae not or 
but slightly dilated; sternal structure variable; precoracoids al- 
ways present; vertebrae procoelian; coccyx attached to two con- 
dyles; no ribs; terminal phalanges assume a variety of shapes. 
This family is represented in the Philippines by six long- 
recognized genera; namely, Oxyglossus, Rana, Staurois, Polype- 
dates, Philautus, and Cornufer. A seventh generic name, Haze- 
lia, is proposed in this paper for a species recently discovered in 
Mindanao and Basilan, characterized by a spiny skin, the skin 
on the head partially involved in the cranial ossification, and 
bony ridges in the interparietal region. 
The largest genus is Rana, which includes twenty-three species, 
or about four-ninths of the Philippine Ranidse. This colossal 
cosmopolitan genus will undoubtedly have to be divided into two 
or more genera. Boulenger® proposes to divide the group oc- 
curring in Papua and Melanesia into three subgeneric groups; 
namely, Rana s. str., Discodeles n. n., and Hylorana Tschudi, using 
the toe disks and the arrangement of the metatarsals as the basis 
for this division. Among the Philippine species there appear 
to be three natural divisions, characterized as follows: 
1. Tips of toes not or but slightly dilated; no enlarged disks; no bony 
“teeth” in lower jaw. Rana vittigera, R. moodiei, and possibly, 
R. parva, belong to this group. 
2. Tips of toes more or less dilated into pads; enlarged “teeth” in 
lower jaw. Rana magna and R. leytensis belong to this group.
