256 REPTILES I'"ROM NIAS. 



A specimen from Sumatra in the collections of the Ley- 

 den Museum quite agrees with our Nias specimen as to 

 length , coloration and pholidosis of the head , except in 

 the number of lower labials, which in the Sumatra-speci- 

 men is 8 instead of 9. So do 2 adult specimens from 

 Java, collected by Boie & Macklot, having 9 lower labials, 

 and classed in our collection under the name of Xenodon 

 purpicrascens Schl. In the same bottle with these 2 speci- 

 mens is a young one (22 c. m.) which agrees with them 

 as to the pholidosis but widely differs in coloration , the 

 latter quite agreeing with Schlegel's figure of Xenodon 

 purpurascens i). There still exists in the collections of the 

 Leyden Museum another young specimen, labelled X. pur- 

 purascens and captured in Sumatra, with 8 upper- and 9 

 lower-labials, which, as regards coloration, shows some resem- 

 blance with S. ajflnis Fischer or <S. trinotatus D. & B. In 

 my opinion all these specimens belong to Simotes purpu- 

 rascens Schl., a species very much subject to variation in 

 coloration as already mentioned by Schlegel himself. 



8. Simotes octolineatus Schneid. 



9. Zapyrus fuscus Gthr. 



10. Dendropjhis picta Gra. 



11. » caudolineata Gray. 



12. Megaerophis Jlaviceps Reinh. 



Two small specimens (about 35 c. m.) in Mr. Pasteur's 

 collection , and one somewhat larger specimen (about 50 

 c. m.) captured in 1862 in Sumatra, are the only speci- 

 mens of this rare species ever sent to the Leyden Museum. 



13. Callophis intestinalis Laur. 

 *14. Platurus Jischeri Jan. 



The occurrence of 2 adult specimens in our collection 

 from Nias, classes this species in the fauna of that island. 

 15. Iclithyophis yluthwsis L.
