Two specimens of this species were found — one by Mr. 

 McNamara at La Carlota, the other by myself in the mountains 

 near Isabela. 



Dendrelaphis terrificus Peters. 



It appears that Dendrelaphis caeruleatus Griffin is a discolored 

 specimen of this species.* A careful comparison of the type 

 with specimens of D. terrificus, from Mindanao, reveals no dif- 

 ferences in scalation. One specimen in the Bureau of Science 

 collection is from Negros. 



Calamaria gervaisii iridescens subsp. nov. 



Type. — No. 201, E. H. T. collection. Canlaon Volcano, Occi- 

 dental Negros, P. I. ; elevation about 900 meters. E. H. Taylor, 

 collector. 



Adult female. — Rostral a little deeper than broad, the part 

 visible above equal to the suture between prefrontals; inter- 

 nasals absent; prefrontal very large, about as broad as long, 

 touching two labials laterally ; loreal absent ; frontal much longer 

 than its distance from the end of snout, twice as wide as supra- 

 oculars, shorter and not as wide as parietals; nostril pierced 

 in a minute nasal ; latter fan-shaped ; one preocular, very small ; 

 supra-ocular scarcely twice as long as wide; one small post- 

 ocular ; five upper labials, last largest, third and fourth entering 

 eye; an elongate posterior temporal behind the fifth labial, 

 bordering the parietal ; mental as deep as wide, touching the chin 

 shields; three labials touch the first pair of chin shields, which 

 are much larger and slightly wider than the second pair; scales 

 in 15 rows; ventrals, 178; subcaudals, 14; anal single; total 

 length, 306 millimeters ; tail, 14. 



Color in life. — Dark iridescent brown above, vidth a very in- 

 distinct series of four darker lines, each minutely powdered 

 with a lighter color. Series of white dots begin on the outer row 

 of scales and continue regularly to the base of tail. A second 

 row of dots begins on the second row of scales, but continues 

 only a short distance. Top of head mottled with dark brovni, 

 the labials almost covered vnth yellowish white. Lower labials 

 and scales on neck and chin yellow, with brown maculations. 

 Ventrals barred across belly with blackish brown and canary- 



* The color on which Griffin's species appears to have been founded seems 

 to be the result of the specimens having been preserved in fonnalin, since 

 specimens of the species of Dendrelaphis, Dryophis, and Crysopelea turn 

 this blue and lose almost all their original markings and color when pre- 

 served in formalin.
