Malay Peninsula Reptiles. — In the Proceedings of this Society 

 for 1896, pp. 856-914, there appeared a paper giving an account 

 of the Eeptiles and Batrachians that I had collected in the Malay 

 Peninsula from March 1895 to April 1896, and a list of the 

 species recorded from that neighbourhood by Cantor, Stoliczka, and 

 others. That list included 176 species of Eeptiles, of which 9, 

 viz., Dermochelys coriacea, Hardella thurgi, Cydemys dhor, Tropi- 

 donotus subminiatus, Macrocalamus lateralis, Hypsirhina indica, 

 Hydrophis nigrocinctits, Aijvjsurus edyouxi, and AmblycepJealiis 

 Icevis weve of doubtful occurrence in the region. In the present 

 list 3 of the doubtful species are recorded for certain, viz., 

 Dermochelys coriacea.^ Macrocalamus lateralis, and Aipysurus eyd,ouxi ; 

 9 more species are added, viz., Geoeynyda grandis, Testudo elongata, 

 Gymnodactylus marmoratus, Mahuia rugifera, Lygosoma maculatam, 

 Zaocys fuscus, Coluber tccniurus, Hypsirhina bocourtil, and 

 Hydrophis gracilis ; Gonatodes ptenangensis becomes a synonym 

 of G. ajffinis; and the names of Hemidactylus gleadovii and 

 Lygosoma jerdonianum are changed to B. broolcii and L. atrocostatum, 

 respectively : thus making a total of 184 species. 



Only one genus, Macrocalamus, is peculiar to the Peninsula, 

 and 6 species, viz., Gonatodes ajjiyiis, Lygosoma singaporense, 

 Cylindrophis lineatus, Macrocalamus lateralis, Calamaria albiventer, 

 and Hypsirhina indica.
