I am now convinced that several distinct species have been 

 mixed up under T. picturatus by Peters & Doria (Ann. Mus. 

 Civ. Genova, XIII, 1878, p. 388), whose view I endorsed in the 

 'Catalogue of Snakes' (I, p. 21 o). The specimens from Halmaheira 

 have been described by Boettger as T. punctiventris and T. hal- 

 mahericus (Zool. Anz. 1895, pp. 29 and 30); those from Coram 

 should be called T. elongatus^ Jan; those from New Guinea and 

 North Australia with lb rows of scales T. picturatus^ Schleg., 

 and T. mairii. Gray; and for those with 17 rows of scales I 

 propose the name T. doriae. 



50. Tropidonotus mairii, Gray. — Moroka, Haveri, Borepata (?) 

 near Port Moresby. 



Frontal once and a half to once and two thirds as long as 

 broad ; eye larger than in T. picturatus; two (exceptionally one)
