388 Mr. G. A. Boulenger on 



XXXVII. — A List of Reptiles and BatracMans from the 

 Island ofNias. By G. A. Boulengek. 



The following list is based on several collections recently trans- 

 mitted to the Natural- History Museum by Dr. M. Schreiber. 

 The collector is Hr. Sandemann. The herpetological fauna 

 of Nias has already formed the subject of a paper by Dr. J. 

 G. Fischer t J who enumerates twenty- two Eeptiles and three 

 Batrachians. Twenty-seven Eeptiles and six Batrachians are 

 recorded below, of which eleven of the former and four of the 

 latter (preceded by an asterisk) are not mentioned in Fischer's 

 list. On the other hand, the following species recorded in the 

 latter have apparently not reached us : — Qehyra mutilata, 

 "Wiegm. ; Tiliqua sulcata, Ptrs. ; Tiliqua percarinata, Ptrs. ; 

 Ablabes ornatus, Schleg. ; Ahlabes haliodirus, Schleg. ; Cal- 

 lophisflaviceps, Cant. ; and Rana chalconota, Schleg. The 

 snake described by Fischer as Simotes affinis, sp. n., I identify 

 as S. lahuanensis, Gthr. ; and his Trimeresurus erythrurus, 

 Cant., var., I suspect to be T. formosus, Schleg. 



REPTILIA. 



*1. Hemidactylus frenatus, D. & B. 



2. Gecko stentor (Cant.). 



3. Gecko monarchus (D. & B.). 



*4. Ptychozoon homalocephalum (Crev.). 



5. Draco volans, L. 



*6. Aphaniotis fusca, Ptrs. 



7. Gonyoceplialus grandis (Gray). 



8. Calotes cristatellus (Kuhl). 



*9. Tiliqua rufescens (Shaw). 



10. Xenopeltis unicolor, Eeinw. 



*11. Calamaria StaJilknecJiti, Stol. 



Three specimens of a Calamaria agree so well in most 

 respects with Stoliczka's description of G. Stahlknechti (Journ. 

 As. Soc. Beng. xlii. 1873, p. 119, pi. xi. fig. 2), from 

 Sumatra, that I can separate them only as a colour-variety. 

 The lower surface of the body is either uniform yellowish or
