the upper reaching the upper surface of the head but not the ver- 

 tical ; two postoculars. Temporals 2 + 2, or 2 + 2 + 2. Ventrals 

 205 ; anal bifid, subcaudals 119. Upper parts brownish-olive, nearly 

 all the scales with black margins; lower parts whitish, the posterior 

 part of the belly and the subcaudals black. 



One specimen was obtained by Dr. Meyer in Luzon ; it is 8| feet 

 long, the tail measuring 26 inches. 



Tropidonotus manadensis. 



Allied to T. stolatus, but with the anterior frontals obtuse in 

 front. Scales in nineteen rows, strongly keeled, except those of the 

 outermost series. Head somewhat depressed, and rather dilated be- 

 hind ; eyes of moderate size, Loreal large, a little longer than deep. 

 One prse-, three postoculars. Eight upper labials, the third, fourth, 

 and fifth entering the orbit. Temporals 2 + 3. Veutrals 138 ; anal 

 bifid ; subcaudals 76. Dentition diacranterian. Upper parts brownish 

 olive; a very indistinct broad darker band runs along the back. 

 The upperside of the head and neck are uniform greenish olive, and 

 behind bordered by a horseshoe-like black band, with the convexity 

 directed backwards, and its branches running downwards on the sides 

 of the neck ; the parts immediately behind this band are yellowish. 

 A rather irregular series of black spots along each side of the ante- 

 rior portion of the abdomen, the remainder of which is white. The 

 sutures between the upper labials black. 



One specimen, 18 inches long (tail 5 inches) has been obtained by 

 Dr. Meyer at Mauado. 



Tropidonotus caljlistus. (Plate XVII. fig. C.) 



Scales in 21 series, all strongly keeled, not emarginate behind. 

 Head rather deep and short ; eye large. Anterior frontals longer 

 than posterior ; occipitals .as long as vertical and posterior frontals 

 together, rounded behind ; loreal deeper than long ; the single ante- 

 rior ocular reaching to the upper surface of the head, but not to the 

 vertical ; four postoculars. Nine upper labials, the fourth, fifth, and 

 sixth entering the orbit ; temporals 2 + 2. The posterior chin-shields 

 louger than the anterior, and much divergent. Ventrals 156 ; anal 

 divided ; subcaudals 76. Maxillary teeth in a continuous series, the 

 posterior scarcely louger than the preceding. 



A greenish-olive band commences from a bright yellow spot on 

 the neck, runs, four scales broad, along the median line of the back 

 and the tail ; it is bordered on each side by a dark brown band, seven 

 scales broad in the middle of its length, encroaching with its zigzag 

 outline upon the median dorsal band. The outermost series pf scales 

 and the corners of the abdominal shields are yellow, this colour 

 forming another straight narrow band. A black baud along each 

 side of the belly. All these bands extend to the end of the tail. 

 Upperside of the head black, with a yellow interocular cross band. 

 Side of the snout and upper lip yellow. 



A single specimen, 12 inches long (tail 2f inches), was obtained
