288 SNAKES OF THE PHILIPPINE ISLANDS 



I have examined recently a single freshly preserved specimen 

 from the Patnanongan Island, east of Polillo. The color above is 

 green, lighter on the sides; the belly is yellowish green; medially 

 there is a series of irregular, reddish brown blotches from the 

 head to the end of the body; there is a broken series of bright 

 yellow spots along the sides of the body, more prominent toward 

 the tail; sometimes the yellow color extends slightly on the ven- 

 tral. The skin between the scales is black and flesh color, al- 

 ternating dorsally, the black area widening on the sides; the 

 edges of the scales over the black area are somewhat bluish. 

 The tail is dark lavender traversed by 16 black bars which do 

 not meet below ; below, behind anus, the tail is blue and yellow, 

 spotted black; on the latter half the color is grayish white. 

 There are 181 ventrals and 59 subcaudals. It, is highly prob- 

 able that this species will later be regarded as a subspecies of 

 Trimeresurus fiavomaculatus. It will be remembered that Gray 

 designated three forms under the names flavovmculata, ornata, 

 and variegata.
