Cyclocorus lineatus Reinhardt. 



A specimen of this common species was taken in the mountains 

 near Zamboanga. 



Ablabes tricolor Schlegel. 



One specimen of this very rare species was taken on Bubuan 

 Island, Tapian Group. It was at rest in the branches of a low 

 shrub. It agrees in remarkable detail with specimens from 

 Palawan in regard to head scales. Ventrals, 137 ; anal divided ; 

 subcaudals (tip of tail missing) , 103. 



Holarcliiis meyerinkii Steindachner. 



A single specimen of this rare snake was taken on Papahag 

 Island, near Bongao. I regard this form specifically distinct 

 from Holarchus octolineatus Schneider." The species is also 

 known from Tawitawi. The type locality is "Sulu Archi- 

 pelago." 



Dendrophis pictus Gmelin. 



One specimen taken on Lapac; a c3conu on Cagayan Sulu. 



Dendrelaphis modestus Boulenger. 



A single male specimen was taken on Bubuan, Tapian Group ; 

 it agrees very well with the type description in regard to scala- 

 tion of head. The dark streak on the side of the head is very 

 dim; there is a bright orange streak along the anterior part 

 of body (almost disappearing in alcohol); ventrals, 175 ; tail 

 with tip missing.

Three specimens of this species were taken in Bongao. It 

 is reported as being common there.

Psalmodynastes pulvenilentus Boie. 



Two specimens were obtained from near the top of Bongao 

 Mountain, at an elevation of 700 meters. Both were under a 

 small log. They show very marked color variations. One is 

 very dark with slightly lighter mottlings; the other is gray
