digits feebly compressed and unicarinate ; limbs rather broadened

Remarks. — The specimen here described contained two em- 

 bryos, almost fully matured. They measure 90 and 86 milli- 

 meters, respectively; the heads are 6.5 millimeters wide; snout 

 to vent, 48; hind leg, 6. The head scales are identical with 

 those of the mother save that the interparietals are a little wider 

 than deep ; the nuchals are present in one specimen, in the other 

 they are broken. I am inclined to regard the presence of the 

 nuchals as a normal character, although the type does not show 

 them. This species is apparently very rare. I have been un- 

 able to find it, and there is no specimen in the Bureau of Science 

 collection. I believe that it is an inhabitant of northern, central, 

 and eastern Luzon. 



It is the largest known species of the genus and is readily 

 recognized by the elongate body. Boulenger gives the following 

 measurements of the type:
