a specimen of lividus exceeding 3 feet 2 inches. I have had within the 

 last year 7 specimens from Dibrugarh and Sadiya (Assam), and more 

 recently eight from Tindharia and Pashok, 1,000 to 4,500 ft. (Eastern 

 Himalayas). Sclater (Journal, Asiatic Soc. of Bengal, Vol. LX., 

 1 1. 246) under the title lividus mentions three specimens in the Indian 

 Museum from Sibsagar and the Garo Hills (Assam), and Saidpur in 

 the Dinajpore District. The latter I could not find, but the two Assam 

 specimens are niger. I have seen 16 examples. 



Sindanus (Boulenger). — Until 1897 the only specimen known had 

 been regarded by Professor Boulenger as an aberrant ccervleus. It 

 differs however in having the costals in 17 or 19 rows in midbody, 

 the vertebral row of scales longer than broad in midbody, and in 

 having a larger number of ventrals. It is also peculiar to Sind. 

 The specimen recorded by Annandale as such from Midnapore* is the 

 next species. 



IValU (Wall). — This very distinct form agrees with the last in 

 the possession of from 17 to 19 scale rows in midbody but differs 

 in having far fewer ventrals, the vertebral row of scales broader 

 than long, the subcaudals entire throughout, the 2nd supralabial 

 markedly narrower than the 3rd, and usually than the ist also, a 

 markedly compressed body, and in colouration and habitat. There 

 are many white, equidistant arches across the back, composed 

 of ovate white spots which have no tendency to be arranged in pairs. 

 The tail is more or less mottled beneath especially towards the tip. 

 It is only known from the Ganges Valley. I obtained 8 specimens 

 in Fyzabad and have seen two more in the St. Joseph's College 

 Museum, Darjeeling, which formed part of the collection of the 

 late Dr. Vincent Richards ; the ideality not known but probably 

 Bengal, also four others in the Indian Museum from Purneah and 

 Midnapore. 



The Common Krait (Bungarus c<zruleus).i 



Norm nclatvre. — (a) Scientific. — Bungarus was applied originally by 

 Daudin in 180o anil is derived from "bungarum pamah," a vernacu- 

 lar name applied according to KussellJ to the banded Krait (Bungarus 

 faseiatus) in Bengal.

| My conception of this us a species is based upon an examination of well over 

 200 specimeas.
