tion, and is almost identical in color and markings. A third 

 specimen, in my own collection, differs from the described form 

 as follows: In my specimen the black blotches are very much 

 wider inclosing elongate grayish spots ventrally, about 28 on 

 body and about an equal number on tail. Head has 2 small 

 spots on frontal and another spot on each parietal ; the black line 

 behind eye is present. Below, body is muddy yellow with a 

 series of irregular black blotches along both sides of ventrals; 

 below, tail is dark, variegated with lighter spots. Width of 

 head is 32 millimeters ; length of head, 45. There are 14 and 

 15 lower labials; the loreal is nearly twice as long as wide; 

 the diameter of eye is less than its distance to nostril.

There is a single fawn-colored form in the Bureau of Science 

 collection (No. 90). It has no markings of any kind. In the 

 size of the head, in body proportions, and in scalation it agrees 

 with the two specimens recorded above. 



The knoATO variation of ventrals in Philippine specimens is 

 261 to 279 ; of subcaudals, 129 to 153. The range for the species 

 given in Boulenger's Catalogue '■' is 248 to 290 and 114 to 156 

 for the ventrals and subcaudals, respectively. The temporals 

 range from 2 -f 2 and 2 -f 3 to 3 + 3 and 3 + 4. The upper 

 labials vary from 8 to 10, and there is consequent variation in the 

 number of labials entering the eye. The species attains a length 

 of more than 2 meters.
