Recorded from Perak and Singapore.

N.B. — Specimens of the harmless Zaocys are sometimes mistaken 

 for the poisonous Hamadryad, JS^aia hunyarus. A friend ouce told 

 me of his Laving killed two Hamadryads in the Larut Hills, and 

 afterwards showed me the bodies ; they were both Zaocys, but I 

 cannot say now if they belonged to this or tbe next species.

Of this fine snake, which has not previously been recorded from 

 the Malay Peninsula, 1 obtained one specimen, a male, on Penang 

 Hill, at an elevation of 1900 feet, in March 1898. Ventrals 195, 

 subcaudals 160. Total length 2965 mm. (or 9 feet 8| inches).

This Eat-Snake has been recorded from Penang, Perak, and 

 Singapore (P. Z. S. 1896, p. 882), and M. Mouhot obtained it 

 in Siam. 



Eecently I have seen seven individuals from the region treated 

 of in this paper : two caught at Bakar Bata (near Alor Star), 

 Kedah ; one from Province Wellesley ; one from the Kuala Kangsa 

 Pass (between Larut and Kinta) in Perak ; one from Kuala 

 Lumpor, Selangor (1568 mm. in total length) ; one I shot in the 

 jungle near Kabin, Siam ; and one was caught atPachim, Siam, by 

 Mrs. Stanley Plower, which measured 1780 mm. (5 feet 10 inches) 

 in total length, and is the biggest Z. Jcorros I have ever seen. 



Toung specimens may have very distinct narrow yellow cross- 

 bars on the anterior part of the body, which become gradually 

 fainter posteriorly. 



Hab. Sikhim Himalayas, Assam, Burma, Western Yunnan, 

 Southern China, Siam, Malay Peninsula, Sumatra, Java.
