96 CAPT. F, WALL ON THE ~~ [ Feb. 3, 
79. DisTIRA BRUGMANSII. Persian Gulf to Chinese Sea. 
Hainan (Boettg.)’. 
80. DistIRA cyANocINcTA. Persian Gulf to Chinese Seas, 
Japan, Papuasia.—I saw one specimen of this snake in the City 
Hall Museum labelled Hydrus major from Hongkong, and one in 
the Shanghai Museum. One conforms to type A, and the other 
to type C of the British Museum Catalogue. 
81. DisTrRA VIPERINA. Persian Gulf to Chinese Sea. 
82. ENHYDRIS HARDWICKII. Bay of Bengal to Chinese Sea and 
Coast of New Guinea.—There are four specimens in the City Hall 
Museum: two, labelled Hydrus major, are from Manila, and two 
from Bangkok. There is one specimen in the Shanghai Museum 
with very markedly spinose tubercles on the median six ventral 
rows of scales. These rows are also enlarged. Labials eight in 
two specimens, in one on both sides and in the other on one side 
only. 
83. PLATURUS LATICAUDATUS”*. Bay of Bengal to Chinese Sea, 
Loo Choos, New Guinea, and Western South Pacific Ocean. 
There are three specimens in the City Hall Museum labelled 
Formosa, and I saw several specimens in Mr. Owston’s collection 
obtained from the Loo Choo Islands. Ventrals 232-246. Sub- 
caudals 32-46. 
84. Puarurus coLtuBRINUS. Bay of Bengal to Chinese Sea, 
Western South Pacific Ocean.—I examined two specimens, both 
in the City Hall Museum, one from Penang and the other of 
uncertain habitat. 
85. Bunearus FascrAtus. Southern Asia from Bengal to 
China, Hongkong (City Hall Mus.).—I obtained one specimen 
from the mainland opposite Hongkong, and I saw two others in 
the City Hall Museum, one from Hongkong and the other from 
the mainland opposite. 
86. Bunearus cANDIDUS. Southern Asia from India to China, 
Hainan, Hongkong (City Hall Mus.), Formosa.—I saw two speci- 
mens in the Shanghai Museum, one in the Siccawei Collection, 
and one in the possession of Mr. Styan in Shanghai. There are 
four specimens in the City Hall Museum, one from Hainan and 
three from Hongkong. All these specimens are of variety B of 
the British Museum Catalogue, viz. multicincta. Postoculars: 
the normal lower shield confluent with the fourth labial on both 
sides in one specimen. Labials six, with the second and third 
1 Under the name of Hydrophis cyanocinctus Boettger (Mat. herp. Faun. von 
China, 1888, p. 88) describes three specimens of what I consider Distira brugmansti, 
collected by Herz in Hainan. 
2 The species described by Boulenger (Cat. Snakes Brit. Mus. i. p. 809) as Platurus 
muelleri | do not believe to be valid, and I think the specimens on which it is 
based will prove to be P. laticaudatus. The only definite point he mentions to 
characterize it is the presence of a median ventral keel in the posterior half of the 
body, and I have found this peculiarity in at least three specimens of what I consider 
undoubted P. laticaudatus.
