DRACO 115 



Remarks.— This species is included in the Philippine fauna 

 solely on the strength of Werner's record. His specimen is 

 from Jolo. I strongly suspect that it is in reality D, rizali Wan- 

 dollek.

Description of species. — (From a series of specimens in the 

 Bureau of Science collection from Zamboanga and Sulu Archi- 

 pelago, collected September and October, 1917, by E. H. Taylor.) 

 Owing to the fact that the sexes are different I shall describe 

 the male and female separately. 



Male. — Rostral large, very miuch broader than high, surround- 

 ed by seven or, usually, eight scales; nasal somev^hat elongate, 

 nostril directed outward and slightly upward and backward, 

 separated from rostral and first labials by two scales and from 

 its fellow by five to seven scales; a series of enlarged strongly 

 keeled scales on head uniformly arranged in Y-shaped formation ; 

 canthus rostralis formed by three or four much-enlarged, sharp- 

 edged scales continuous with the superciliary edge, the latter 

 also sharp and formed of enlarged scales which continue to 

 above middle of eye and then suddenly cease ; a conical, or some- 

 what compressed, prominent spine on posterior part of super- 

 ciliary edge; another prominent conical tubercle on posterior 

 part of orbit; scales on supraorbital areas large, somewhat 

 keeled, the enlarged scales separated from the superciliary edge 

 by several rows of minute scales ; occipital scales large, irregular, 

 rugose; a row of scales under orbit, posterior side of orbit 

 usually enlarged with a row of enlarged scales extending back to 

 above tympanum; later naked, about size of eye opening, with 

 usually an elongate, slightly enlarged scale immediately in 

 front; nine to eleven upper labials, the last usually elongate, 

 first very small; an enlarged scale usually above last labial; 

 labials separated from suboculars by two or three scale rows; 

 mental as large as rostral, bordered by seven or eight scales; 

 gular apipendage a little longer than head, much narrowed to- 

 ward tip ; nuchal crest very prominent ; lateral crests very low ; 

 two spiny scales back of temporal region above tympanum ; a row 

 of enlarged, keeled distant scales on sides varying in distinctness, 

 very prominent or dim, more or less continuous with lateral 

 nuchal crests; wing membranes moderate; scales on tail keeled, 

 those on back only slightly or not keeled ; about twenty-five rows
