19. Cyclophis major (Gthr.). Common near Kiu-kiang. 
20. Tropidonotus annularis (Hallow.). Common near Kiu-kiang. 
21. Tropidonotus tigrinus (Boie). Very common near Kiu-kiang. 
22. Tropidonotus swinhonis (Gthr.). Ichang. 
23. Tropidonotus macrophthalmus (Gthr.). Kia-tiang-fu in Sze 
Chuen (alt. 1,070 ft.). 
24, Ophites septentrionalis (Gthr.). One specimen from the neigh- 
bourhood of Kiu-kiang. 
25. Lycodon rufozonatus (Cant.). Common at Kiu-kiang and at. 
Kia-tiang-fu, Sze Chuen. 
26. Bungarus semifasciatus (Kuhl). One specimen from the country 
near Kiu-kiazig. 
27. Callophis annularis (Gthy.). One specimen from the country 
near Kiu-kiang. 
28. Trimeresurus canthomelas, sp. n. (Plate I. Fig. A.) 
The second upper labial shield forms the front part of the facial pit; 
upper part of the snout with three small shields in front. Supraciliary 
scute large, not divided. Scales in twenty-one rows, keeled. Ventrals 
185, 189; subcaudals 59, 68: anal and preanal not divided. Black, each 
scale with an elongate greenish-yellow spot, the spot frequently including 
small black specks. By the modification of the extent of the black colour 
on the scales a chain of subrhombic spots is formed along the vertebral 
line; the yellow of the scales within each rhombic spot is of a more 
reddish shade. Upper part of the head black, with a pattern of narrow 
symmetrical lines; a deep black band from the eye to the angle of the 
mouth; labial shields yellow, with a series of black spots on the sutures. 
A rather indistinct row of black spots along the sides of the body. Lower 
parts yellow, marbled with black, the black colour predominating in the 
posterior half of the length. 
Five specimens of this beautiful snake were obtained at Ichang by 
Mr. Pratt, one of the largest being thirty-one inches long, the tail measur- 
ing five inches. Mr. Boulenger considers it to be identical with T.jerdonii 
(Gthr.) from the Khassya Hills, but by its striking coloration it forms at 
any rate a well-marked variety. It feeds on mice; and the specimen I 
extracted from its stomach proved to be an undescribed species. 
29, Trimeresurus monticola (Gthr.). Kia-tiang-fu in the province 
of Sze Chuen (alt. 1,070 ft.).
