107 



Coloi- in life. — Bluish brown above with three darker lines 

 beginning near the head and continuing to end of tail ; these are 

 scarcely visible anteriorly ; each line incloses a series of small, 

 dim, whitish yellow dots; ventrals with a heavy brownish line, 

 extending the length of body ; a small whitish dot on end of each 

 ventral, but not continuing on subcaudals; scattered triangular 

 black spots on ventrals ; head markings more or less indistinct, 

 regular; labials lighter with a dull stripe below eye, the lighter

Variation. — There is much variation in certain scale elements 

 in this species and it appears to be associated with geographical 

 distribution. The Mindanao forms vary uniformly in scale 

 count from Negros or Luzon specimens, and might be regarded 

 as worthy of subspecific rank. Specimens from Samar and 

 Leyte or southern Luzon would probably connect the various 

 forms. Table 17 shows the differences that exist between the 

 southern and the northern groups. There is a marked differ- 

 ence between the tail length of the Mindanao and the tail length 

 of the northern specimens, especially in the males, the average 

 being about 16 millimeters. The Mindanao specimens average
