REPTILIA 



Indian Cobra. Naia tripudians. Plato LXI. 



The general coloration of the fundus oculi in this Snake is light 

 gray-blue, sparsely dotted with pigment of a similar but deeper color. 

 The whole background is regularly covered with opaque nerve 

 fibres. From the button-like optic disc arise three vessels, appar- 

 ently two arteries of small size and one larger vessel — probably a 

 vein. The centre of the papilla shows the remains or the undeveloped 

 tissues of a pecten.
