PYTHON CURTUS. 245 



long appear in the first number of the Annals of the 

 Leyden Museum. 



A short diagnosis, sufficient for identification of speci- 

 mens , which might reach Europe from the same or from 

 adjacent localities, may here follow. 



Body short , compressed before the vent , less so towards 

 the middle of the trunk and the neck. Internasals as 

 long as , but much less broad than frontonasal plates. Two 

 rather large prefrontals, frontal divided into two halves, 

 each of them smaller than either prefontal or frontonasal. 

 About five pairs of parietals , the first of which are the 

 largest and touch the supra-oculars and frontals with their 

 edges. Three supra-oculars on each side. Two grooves 

 in the rostral plate and one in each of the two front 

 pairs of upper labials. On each side eleven upper labials 

 and sixteen lower labials; five or six of the latter are 

 indistinctly pitted and brown-streaked anteriorly. Eye com- 

 paratively smaller than in other Pythons. 



Only 160 ventral shields from throat to vent, 32 sub- 

 caudal ones , divided in the middle. Ground-colour (in 

 spirits') a light brownish yellow with dark brown markings 

 and clouds , having about the pattern of the allied species 

 (P. reticulatus , P. hivittatus). Upper surface of the head 

 light all over. A broad dark streak runs along the sides 

 of the head , passes horizontally through the eye , and is 

 interrupted by a narrow light one from the eye to the 

 seventh and eighth upper labials. Behind the parietals a 

 median light line is marked off by darker shades to the 

 right and left. 



The specimen was procured by S. Muller, the naturalist 

 to the Leyden Museum , from that part of Sumatra which 

 lies between Padang and Indrapura. It measures 46 cm.
