cobra. In a well grown adult I have measured the fangs one-eighth 

 of an inch along the straight, and I think in the largest specimens they 

 will be found scarcely to exceed this length. They are caualiculate 

 with a very obvious seam on the anterior face where the circumflexed 

 margins of the walls forming the canal meet. Often two fully oper- 

 ative fangs occur side by side in the same jaw. Behind these the 

 maxilla is hollowed to receive the sac in which the reserve fangs 

 develop, and behind this again it gives origin to four small teeth, 

 which are grooved though in no way connected with the poison 

 apparatus. 



Glands. — These structures, as far as 1 can judge, are relatively about 

 as well developed as in the cobra. They are smooth, somewhat 

 retort-shaped, and when cut into reveal a cancellous structure similar 

 to the appearance of a sponge. 



Poison. Physical properties. — I have rarely seen the poison " in 

 vitro " either in the liquid or dried state, and can find no special 

 references to its re-action, taste, and appearances, etc. To the naked 

 eye it appears, when fluid, much like cobra venom, a clear fluid, with 

 the consistency and colour of pale salad oil. 



Quantity. — I have no records of the yield of a single gland nor can 

 I find any in literature, but the yield is, I think, very considerably 

 less than that of a cobra of the same size.
