black line through the eye is narrower and more distinctly defined, and 

 is even continued forward round the nose ; and the labial plates above 

 and below are more or less black-margined. Whether the two races are 

 local, or merely casual varieties of the same, remains for observation to 

 determine. 



Tr. nigrocinctus, nobis, n. s. Another beautiful species, affined to 

 the last, but at once distinguished from it, structurally, by the extra- 

 ordinarily large size of its penultimate and ante-penultimate upper labials 

 (posterior to the eye) : the occipital plates are also proportionally smaller. 

 Colour, olive-grey above, passing (like the last) to bright green towards 

 the head ; and conspicuously marked throughout with a series of about 

 50 narrow transverse black bands, some perfect, others broken and alter- 

 nating: head with two broad black lateral streaks, one from behind the 

 eye to the cleft of the mouth, the other below the eye : a narrow and 

 indistinct black band edging the occipital plates posteriorly ; and behind 

 this, a broad pale collar, which was probably bright red above in the living 

 Snake ; and this red colour would seem to have extended upon the cheeks 

 between the two broad black stria : lower-parts white, each scuta begin- 

 ning to be margined with grey from about the twentieth ; and this grey 

 gradually darkening posteriorly, until towards and upon the tail it 

 becomes blackish and occupies about half of each scuta ; besides which a 

 row of small lateral spots may be traced, corresponding with those of the 

 preceding and certain other species. Rows of scales 17 : abdominal scutcz 

 160 \ subcaudal scutellce 81 pairs : length of specimen 26| in., of which 

 tail 6^ in. 



Bungarus flaviceps, J. Keinwardt, apud Cantor, J. A. S. XVI, 1033. 

 Specimen 46| in. long, of which tail 7i in.; the hexagonal row of scales 

 along the spine highly compressed and tectiform. As shewn by the pre- 

 sent specimen, Dr. Cantor's supposed distinctions of colouring of the 

 adult and young are rather those of individual variation.* 



Megalophrts guttulata, nobis, n. s. A species of remarkable 

 beauty ; and belonging to a very different subtype from that to which the 

 great ' edible frog' of Sikim (M. gigas, nobis, J. A. S. XXIII, 299), is 

 referable. Tympanic membrane distinct, though much contracted : fore 

 and hind-limbs subequal ; the hind-toes short and but slightly webbed. 

 Length of the larger of two specimens, from snout to vent, 3£ in. ; of 

 extended fore-limb 2£ in. ; and of extended hind-limb 3f in. In the 

 great Sikim Megalophrts (?), the hind-limbs are nearly four times the 



* Unfortunately, this rare Snake has received injury from the attacks of ants. 

 When alive, its head and tail were bright red, as Dr. Cantor describes.
