108 The Philippine Journal of Science 



Measurements. — Total length, 125 millimeters; snout to vent, 

 108 ; tail, 17 ; width of head, 4.5. 



Remarks. — ^While no specimen of D. novse-guineae is at hand 

 for comparison, I have no doubt as to the distinctness of this 

 species. The difference in the proportional length of the body 

 and tail is especially evident, while the position and distinctness 

 of the eye, the smaller size of the interparietal, and the color- 

 ation are all distinctive characters. The head is not depressed, 

 but is the same thickness from end of snout to the neck. A 

 single specimen was found on a small rocky hill emerging from 

 the great swamp not far from the mouth of Agusan River. 

 This is the first record of this family and genus in the Phil- 

 ippines. A second specimen has been taken on Canlaon Volcano 

 on the Island of Negros, at an elevation of about 915 meters.
