eyes; a dark blotch on the temporals, which is connected with 

 the band; small spots on the nasals; chin yellow; on the edges 

 of one-half of the ventrals are small spots that involve one or 

 two of the body scales ; on each alternate ventral are two larger 

 rectangular spots ; throat variously spotted with dark. Ventral 

 surface yellow; below tail, yellowish with no or very few spots. 

 Total length, 299 millimeters; tail, 59. 



Variation. — A second specimen taken at the same locality (No. 

 41, E. H. T. collection) is very different in scalation, but it seems 

 to be an abnormal specimen. A small loreal is present on the 

 right side of the head; two preoculars are fused into one on 

 the left side. The first lower labial on both sides is broken in 

 two, making it appear that there is a pair of minute chin shields 

 behind the mental. The temporal elements on the right side 

 are not normal, the parietal is broken and there are two anterior 

 temporals. In coloration and marking they are practically 

 identical.

Remarks. — Both specimens are from Bunawan, Agusan. 

 They were collected by myself from under piles of sod. This 

 form is obviously different from other Philippine species. The 

 markings are distinctive; the loreal is absent and only a single 

 labial enters the eye ; two preoculars are present. These charac- 

 ters together with many minor differences separate it from 

 H. meyerlinkii and H. ancorus. From iif. burksi it is separated 

 by markings and coloration and the above mentioned characters, 

 save that of the single labial entering the eye in which the two 

 forms agree.
