Habits. A female killed in Bangkok on the 17th January, 1898, 

 contained nineteen eggs, measuring, greater axis 53 mm., lesser 

 axis 84 mm. The Siamese assured me they sometimes lose 

 buffaloes through the Cobras which frequent the fields where the 

 cattle graze, the bite of the snake being sufficiently poisonous to 

 kill such large animals.

 olive-brown to deep black, with brownish head. Below grey or 

 bluish black. Lips, chin, and throat bright yellow. " Hood " 

 ornamented with (usually) a very well-defined bright yellow Q, 

 edged both inside and out with black. Under surface of " hood " 

 yellow, with a black spot on each side. Behind the " hood " a 

 yellow collar, broad beneath, and above mottled with brown or 

 dividing into two very narrow lines, the anterior straight across 

 the neck, the posterior chevron-shaped, pointing backward. 



Perak Cobra. — Above uniform pale yellowish brown, no markings 

 on " hood," which when expanded looks very yellow, owing to the 

 pale yellow skin showing between the scales. Underneath the neck 

 are a short median series of indistinct brownish spots, and three 

 pairs of brownish spots. Eemainder of lower surface pale yellow.
