Of this grass snake, said by Wall and Stanley to be common about 

 Shanghai, the National Museum had no specimen at the time of the 

 publication of the Herpetology of Japan. Thanks to the thoughtful- 

 ness of D. C. Jansen we have now a fine adult male of typical colora- 

 tion and with the typical number of two strongly keeled dorsal scale 

 rows. It has 16 scale rows, 194 ventrals; 2 anals; 109 pairs of sub- 

 caudals; 8 supralabials ; 2+2 temporals. 



ZAOCYS NIGROMARGINATUS (Bljth) 



1854. Coluber nigromarginatus Blyth, Journ. Asiat, Soc. Bengal, vol. 23, 

 no. 3, p. 290 (type locality, vicinity of Darjiling. Himalaya; cotypes in 

 Mus. Calcutta; Capt. W. L. Sherwill, collector).

 fig. B (Nepal; Sikkim ; Khasia). — Boxtlengeb, Cat. Snakes Brit. Mus., vol.

1858. Corypliodon car hiatus Gttenthek, Cat. Col. Snakes Brit. Mus., p. 112 

 (type locality, Borneo, Himalaya, Chusan"; cotypes in Brit. Mus.) (part 

 only; Khasia, Sikkim). 



1867. Corypliodon dhiimnades Jan, Icon. Ophid., livr. 23, pi. 4, fig. 1 (Hima- 

 laya) (not of Cantor, 1842). 



Zaocys dhunvnades Guenther, Ann. Mus. Zool. St. P^tersbourg, vol. 1, 

 1896, p. 205 (Lunganfu, Szechwan). 



A. series of six specimens, adult, adolescent, and young, collected 

 by D. C. Graham in Szechwan, introduce this Himalayan species into 

 the Chinese fauna as distinguished from the Chinese Z. dhumnades, 

 for I have but little doubt that the specimen collected by Berezowski 

 at Lunganfu and recorded by Guenther under the latter name is 

 identical with Graham's specimens from Suifu and Mount Omei. 



As will be seen from the list given below, the number of subcaudals 

 is in excess of those typical of Z. dhumnudes. In addition, the num- 

 ber of keeled rows is six in all the specimens, except the youngest one 

 (No. 63414) in which only four scales as keeled, the same as in Z. 

 nigromarginatus . Moreover, the color pattern, which is only plainly 

 visible in the younger ones, is that of the latter species as distin- 



^■^ Restricted by Guenther in 1864, Kept. Brit. India, p. 256, to specimen a from Borneo.
