120 F. Stoliczka — Malayan Beptilia and Amphibia. [No. 2, 



obtuse angle behind ; the shields of the second pair are only about half 

 the size of the first, entirely separated from each other by two scale-like 

 shields following each other, and by two other somewhat larger shields 

 from the first very large ventral. Scales smooth, in thirteen rows ; ventrals 

 163, anal entire, subcaudals 22, the last single occupying the shortly pointed 

 end of the tail. 



Uniform irridescent brownish black above, the two outer series of scales 

 on either side mostly white ; upper labials spotted with yellow, the fifth 

 labial being almost entirely yellow. Lower side, beginning a short distance 

 from the throat, with two or sometimes three ventral shields alternately yel- 

 lowish white and black, the black colour encroaching laterally upwards upon 

 the yellowish white lateral bands, and being longitudinally connected along 

 the edges of the ventrals and subcaudals ; the latter have besides an inter- 

 rupted blackish line along the middle, and the pale colour is tinged with 

 vermilion. Possibly the red colour extended over the whole of the light 

 coloration during the life of the snake. 



The only specimen examined was sent to me with several other species 

 by my friend Mr. Stahlknecht of Singapore ; he collected the same near 

 Dilli on Sumatra. 



In general aspect the species resembles G. LinncBi, but differs essential- 

 ly in several points of its structure. It a:lso does not agree with any of the 

 species more recently described by Bleeker and Edeling, or figured by Jan. 



OXTCALAMUS LO^GICEPS. 



A single specimen of this rare snake was in the Penang collection ; it 

 measures seven inches of which the tail is one. 



The following may be added to Cantor's and Griinther's descriptions : 



The rostral shield is of moderate size, reaching with its angle to the 

 upper surface of the head ; anterior frontals small, each about one-third the 

 size of a posterior ; the suture separating the two anterior frontals is only 

 two-fifths of the length of the suture between the posterior frontals ; vertical 

 six sided, the sides touching the supraciliaries being parallel to each 

 other ; one supraciliary not quite as wide as half the width of the vertical ; 

 occipitals nearly double the length of the vertical, reaching down on either 

 side to the postocular ; nasal in a single shield. 



Vent. 137, anal entire, subcaudals 29. 



Uniform irridescent black above and below, many of the ventrals and 

 subcaudals with paler posterior edges ; a pale yellowish spot on the fifth 

 upper labial and a second one on each side of the throat. 



SiMOTES BICATENATUS. 



In several specimens, the dark dorsal band is divided by a pale reddish
