FURTHER NOTES ON SNAKES FROM THE CHIN HILLS. 775 



Ingested was found the remains of a large " Ophisaurus gracilis, '* 

 swallowed head foremost as seems usual. 



Callophis macclellandi. (var : typica). — One specimen (51/10) 

 was found in a nullah with its head much battered on 2nd June. 

 Its length was 27'5 inches, tail 2-25 inches. The ventrals were 

 200, and subcaudals 20. The head had the usual ivory white 

 band ; the black bands were 25, of which 2 were on the tail. In 

 addition there was a dorso-lateral series of black spots intermediate 

 between the black bands. These spots commence after the 5th 

 band and occur after each band except the 8th and 9th and the 

 last on the tail, but the spot on the left after the last band but two 

 and the last but one on the body has disappeared, and in these two 

 places the intermediate black blotch of the belly has become dis- 

 torted upwards on to the flank.

In the two first cases a shrew had been swallowed. The last had 

 some abnormalities in the subcaudals as follows: — the 1st to 6th 

 from the vent are entire, the 7th to 15th divided, and the 16th to 

 22nd entire. The supracaudals were in even rows unaffected by 

 these anomalies.
