21. Calamaria sumatrana, Edeling. M., I. 



Three specimens of this little-known Calamaria were obtained, 

 two by Prof. Moesch, one by Mr. Iverseu. The following descrip- 

 tion is drawn up from these specimens : — 



Rostral a little broader than deep ; frontal longer than broad, a 

 little shorter than the parietals, rather more than twice as broad as 

 the supraocular ; one prse- and one post ocular ; five upper labials, 

 third and fourth entering the eye ; two pairs of chin-shields in con- 

 tact with each other, the anterior in contact with the mental. Scales 

 in 13 rows. Ventrals 168, 176, 174 ; anal entire; subcaudals 13, 12, 

 1 2. Tail pointed. Reddish brown above, with five black longitudinal 

 lines ; each scale of the outer row with a white spot ; a yellow collar 

 on the nape, narrowly interrupted in the middle, and a similar 

 marking at the base of the tail ; lower parts uniform yellowish, with 

 a black line along the middle of the tail. 



Total length 265 millim. ; tail 12. 



This Calamaria resembles strikingly, at a first glance, the Javan C. 

 quadrimaculaia, from which it differs in having five instead of four 

 upper labials, and in the separation of the first pair of lower labials 

 by the anterior chin-shields. Sjjecimens from Kiu Kiang and Hong 

 Kong have recently been referred ' to C. quadrimaculaia, but, in 

 spite of their similar coloration, belong to a distinct species, for which 

 I propose the name of C. septentrionnlis. C. septentrional is differs 

 from C. quadrimaculaia in the frontal being as broad as long and 

 in the tail being rounded at the end.

I suspect Elapoides annvlatus, Sauvage (1884), to be founded on 

 a young specimen of this species.

Otherwise identical specimens, from the same locality, have either 

 19 or 21 rows of scales.
