XIX. — SNAKES FROM SUMATRA 



BY Dr. Th. W. VAN LIDTH DE JEUDE. 



On the following pages I give a list of the snakes collected by Mr. 

 Edw. Jacobson, during various excursions, which he made in the Padang 

 Highlands and in the country of Korintji. Mr. Jacobson, to whom the 

 Leiden Museum is already indebted for many valuable collections of 

 East-Indian animals, kindly presented these snakes to our Museum. 



The collection though not a large one is a very valuable one, and 

 proves the importance of a careful investigation of the fauna of Central- 

 Sumatra. Of the 36 species, 2 species and one variety are new to science, 

 viz. Pseucloxenodon Jacobsonii, Galamaria crassa, and Simotes annulifer 

 Blgr. var. annulata. Moreover the collection contains a specimen of Ano- 

 malocliilus iveberi Lidth, which is, as far as I know of, the second known 

 specimen of this interesting form, the typical specimen being collected 

 in Kaju-tanam, Sumatra by Prof. Max Weber. Coluber taeniurus Cope 

 and Calamaria leucocephala Dum. and Bibr. were until now not represented 

 in our collections. 



1. Python reticulatus (Schneider). 



A young specimen from Muara Kiawai, Ophir districts, Padang High- 

 lands, YI, 1915. 



Ventrals 309. Anal undivided, subcaudals 91/91. 



2. Anomalochilus weberi Lidth. 



One specimen from Tanangtalu, Ophir districts, Padang Highlands, V, 1 91 5. 



As to the pholidosis of the head and the number of scales on the 

 body this specimen very well agrees with the typical specimen in the 

 Leiden Museum. Frontal quadrangular, much broader than long, the 

 anterior angle very obtuse, nearly straight, the posterior angle rounded. 

 Ventrals 253, anal divided, subcaudals 3 + 4/4. Scales in 21 rows. 



As to the coloration this specimen is of a brown colour, the scales 

 edged with light, along the sides light spots, mostly alternating, on the 

 anterior half of the body these spots occur more rarely, two small round 

 spots on the tip of the tail, no white spots on the praefrontals and the 

 frontal. Lower surface with irregular light spots, placed in pairs or con- 

 fluent.
