. The snakes of the Philippine Islands. Snakes. DRYOPHIS 223. Kin. 19. Drijophis prcnculoris sp. nov. ; drawing: of a Polillo specimen; a, head. dorsal \ie\v ; h, bead, lateral view- frontal at least one and a half times as long as wide; very narrow behind; in its widest part it does not equal width of supraoculars; parietals large, elongate; supraoculars large and projecting, so that eye is hardly visible from above; canthus rostralis very sharp; 2 large preoculars, the upper separating supraoculars from prefrontals; 2 loreals, the posterior largest; nostril in a very elongate, very narrow nasal; 2 small post- oculars ; temporals 2 -|~ 3; parie- tals bordered by 3 temporals; 9 upper labials in the following order of size: sixth, fifth, eighth, second, first, third, seventh, fourth, ninth; fourth, fifth, and sixth enter eye; mental very small, triangular; 7 lower labials in the following order of size: fifth, fourth, sixth, seventh, first, third, second; 4 labials touch first pair of chin shields; scales smooth, in 15 rows; ventrals, 227, keeled laterally; subcaudals, 110; anal undivided; eye large, equal to half its distance from snout; latter acuminate, projecting. Color in life.—Bluish green tending toward yellowish green on sides, with no markings of any sort; head greenish; belly green- ish with a narrow cream line running full length of body and tail on outer part of ventrals and anals. Remai'ks.—This species is widely distributed, from Mindanao to Luzon. In the character of the anal shield and in the arrange- ment of the preoculars it is constant. In Negros and Panay there occurs what appears to be a variety of the species. It is red and doubtless represents what has been regarded by other authors as Dryophis prasinus xanthozonus. However, Druophis xanthozona is a distinct species and is probably confined to southeastern Asia and Java. I regard the red foi'm here as merely a color variety of Dryophis preocidaris. A red form also occurs in Dryophis prasinu
