SIAPHOS 221 



ities. This is the first record of this species * in the Islands. 

 Known also from Celebes and Sanghir Islands, the latter being 

 the type locality ; the type was collected there by Dr. A. Meyer.

Description of species. — (From the type. No. 894, E. H. Tay- 

 lor collection; collected on Canlaon Volcano, Negros, De- 

 cember 23, 1915, elevation 900 meters, by E. H. Taylor.) 

 Rostral large, covering the end of the conical snout, forming a 

 broad suture with frontonasal, about equal to that with nasals; 

 frontonasal very large, convex anteriorly and concave pos- 

 teriorly, forming its largest suture with frontal; prefrontals 

 absent; frontal rather triangular in shape, longer than broad, 

 the anterior part rounding, not as wide as supraocular region; 

 frontoparietals fused into a single large scale, which is distinctly 

 wider than supraocular region, and in contact with three supra- 

 oculars; interparietal as wide as frontal, but shorter; parietals 

 elongate, diagonal, more than twice as long as wide, joined be- 

 hind interparietal, in contact anteriorly with two very small 

 postoculars; three or four pairs of enlarged nuchals; nostril 

 pierced in the middle of the single nasal, which is followed 

 by two frenals subequal in size, as high as nasal; two super- 

 imposed preoculars; eight superciliaries, anterior largest; four 

 supraoculars, two touching frontal, second widest; two pairs 

 of slightly enlarged postoculars and a row of scales above upper 



* Except for the disk present on the lower eyelid, this species might be 

 united with *S. quadrivittatum. The coloration and markings are nearly 

 identical, and they vary in no other essential detail save the one mentioned. 

 Peters states of his species, ''Unteres Augenlid undurchsichtig und Trom- 

 melfell vollstandig von dachziegelformigen Schuppen versteckt." While he 

 states that the eyelid is opaque, he neither mentions the presence of a disk, 

 nor states that the eyelid is scaled. Boulenger's description (op. cit.) 

 which appears to be taken from Peters's description (op. cit.) of type, states 

 "Lower eyelid scaly." Whether or not he examined the type is not stated. 

 I am strongly inclined to believe that the two forms, infralineolatura and 

 quadrivittatum are identical. I shall, however, retain them as separate 

 species until the types of the latter are examined on the point in question. 

 The fact that the type locality of 5. quadrivittatum is Mindanao, with 

 specimens known from Celebes, makes the habitat of the two species iden- 

 tical. If the types of S. quadrivittatum have the lower lids scaled, it 

 might prove a case of individual variation. Nelly de Rooij (op. cit.) 

 retains the two separate, and also states that the lower eyelid is scaled.
