II. Coluber prasinus, Blyth. 



A specimen from Pu-piao (alt. 4,600 feet) in the Yung-chang 

 Fu district. 



12, Helicops schistosus subsp. yunnanensis (x'lnderson). 



Atretium schistosum, Daud., var. yunnanensis, Anderson, Anat. 



Zool. Res. Yunnan Exp., p. 822 (1878). 

 Helicops schistosus var. andersoni, Wall, Rec. Ind. Mus., iii, p. 146 



(1909). 



A specimen from Mong Wan must be attributed to this race, 

 the internasal being divided into three shields as in two of the 

 three original specimens, which are the types of Wall's variety as 

 well as of Anderson's. So far as I am aware this form has only 

 been found in Yunnan. It is distinguished from the typical form 

 of the species by the splitting of the iiiternasal into either two or 

 three shields. 



13. Tropidonotus stolatus (Linn.). 



A specimen from Lo-po-ssu-chuang (Mong Hum) (alt. ca. 5,000 

 feet). The markings are unusually conspicuous owing to the pale 

 ground-colour of the dorsal surface, but I am not sure how far this 

 is due to partial maceration of the specimen. 



14. Tropidonotus nuchalis, Boulenger. 



Botdenger, Cat. Snakes Brit. Mus., i, p. 218, pi. xiii, fig. i. 



I attribute to this species, which was originally described 

 from the upper basin of the Yang-tse-kiang, two small specimens, 

 one (total length 31 cm.) from Tengyueh, the other (total length 

 43 cm.) from Pe-lien (alt. 5,800 feet) in the same district. They 

 agree fairly well with Boulenger's description and have the mid- 

 dorsal groove on the neck (which doubtless suggested the specific 

 name) conspicuously present ; but in one the suture between the 

 internasals is distinctly and in the other slightly shorter than that 

 between the fronto-parietals. The smaller specimen is dark with a 

 pale transverse bar running across the neck and interrupted by 

 the nuchal groove, and with a minute white spot on each side of 

 a large number of the dorsal and lateral scales. In the larger 

 specimen these minute spots have disappeared and the nuchal 

 cross-bar is represented by a brownish spot on either side. The 

 dark lines on the sides of the head were apparently faint or absent 

 in both specimens, but their state of preservation is too bad to 

 justify an exact statement on this point. 



15. Bungarus fasciatus (Schneider). 



A young specimen from Chu-tung (alt. 5,500 feet) in the 

 Yung-ping Hsien district.
