CALAMARIA ALBI VENTER. 197 



Three specimens, from 8 to 9 inches long, were collected by Mouhot in the southern parts 

 of Siam, and in the Lao Mountains, Cochinchina. We have given three views of the head, 

 of twice its natural size, and a portion of the belly, to show its peculiar coloration. 



Calamakia quadkimaculata. 



Calamaria quadrimaculata, Dutn. ^ Bibr. vii. p. 73. 



Upper labials four ; the fu'st pair of lower labials are in contact with each other ; there 

 is no azygos shield in contact with the anterior chin-shields. Vertical shield as broad as 

 long, six-sided, half as large as an occipital. The circumference of the body is one-fourteenth 

 of the total length. Ventral shields 136-145 ; subcaudals 13. Light brownish, with five or 

 seven brown longitudinal lines ; neck with a broad blackish-brown collar, edged with white 

 anteriorly and posteriorly. Lower parts uniform white ; a faint blackish subcaudal line. 

 Upper part of the taU with two pairs of white spots, one at its base, and the other on its 

 extremity. 



This species is found in Java. Having seen a specimen from General Hardwicke's collec- 

 tion, it is possible that it occurs also in British India. For this reason, and for comparison 

 with C. siamensis, we have admitted it in the present work. 



Calamaria albiventer.

Upper labials five ; the first pair of lower labials are not in contact with each other ; there 

 is no azygos shield in contact with the hind part of the anterior chin-shields. The cii'cum- 

 ference of the body is one-twelfth or one-thirteenth of the total length. Ventral shields 

 160-166, subcaudals 16-17. Head brown, vpith darker dots; trunk brown, with four ver- 

 milion longitudinal streaks, the outer of which runs along the joining edges of the two 

 outer series of scales; a third, rather indistinct, pair of streaks run along the joining edges 

 of the third and fourth outer series of scales. Belly carmine, the brown coloration of the 

 side just touching the margin of the ventral shields. A black serrated line along the middle 

 of the subcaudals. 



Pinang. Length 11 inches. The young specimens mentioned by Cantor appear to belong 



to another species.
