198 OPHIDIA. 



Calamaria niqro-alba. (Plate XVIIl. fig. C.) 



Calamaria liimbricoidea, var., Cantor, Mai. Rept. p. 61 (not Boie). 



Upper labials five ; the first 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, much smaller than an occipital, with an acute posterior angle. The circumference 

 of the body is one-fourteenth or one-eighteenth of the total length. Ventral shields 

 147(-154)-166 ; subcaudals 30(-29)-25. Upper parts blackish, head somewhat lighter, all 

 the lower parts and the outer series of scales whitish, immaculate, both colours being well 

 defined ; a faint blackish subcaudal line. 



Pinang. Length 12-13 inches. This species has been confounded by Cantor with C. lum- 

 hricoidea, from Java, which differs in the arrangement of the labial shields. C. modesta, from 

 Java, is more closely allied to our species, but differs in its coloration, and in hanng a greater 

 number of ventral shields and a shorter tail. The three views of the head on Plate XVIII. 

 are of twice the natural size, and are taken from one of Cantor's typical specimens. 



Calamaria leucocephala. 



Calamaria leucocephala, Drnn. ^ Bibr. vii. p. 83. 



Upper labials five ; the first pair of lower labials are in contact with each other ; there is 

 no azygos shield in contact with the anterior chin-shields. Vertical shield broader than 

 long, six-sided, with an obtuse angle posteriorly and anteriorly. Ventral shields 136 ; sub- 

 caudals 37. Black above; head, neck, the two outer series of scales, and the lower parts 

 white. 



The only specimen known is in the Fort Pitt Museum at Chatham, and is 9 inches long. 

 It is probably from British India. 



MACROCALAMUS, Gthr. 



Body cylindrical, stout ; head of moderate length, slightly depressed, not 

 distinct from neck ; eye of moderate size, with round pupil ; tail short. 

 Only one pair of frontals ; nasal simple, nostril between nasal and first 

 labial ; loreal none, united with frontal ; one anterior and one posterior 

 ocular ; eight upper labials. Scales smooth, rounded, polished, in thirteen 

 series ; anal entire ; subcaudals two-rowed. Teeth equal. 



East Indies.
