on the back of the neck, somewhat resembling 
a pair of spectacles. These snakes are used by 
the Indian jugglers, in their exhibitions. 
The Coral Snakes ( Elaps ) are very similar in 
form, but the neck is not dilatable, and the 
dorsal scales are broad; many of these are 
marked with black and bright coloured bands, 
as Elaps corailinus. 
The Flat Tailed Coral Snake (Platurus) found 
in the Indian Seas, differs from the other Coral 
Snakes, by its tail being flattened like the Sea 
Snakes. 
Cases 7—13 contain the snakes which have a 
regular row of teeth on the edge of the upper 
jaw. Most of these have long conical tails, 
and broad plates under the abdomen. These 
species are, in general, innocent; a few have 
some of the upper lateral teeth rather larger 
than the rest, and grooved on the hinder edge, 
the groove communicating with a gland placed 
on the side of the face, but their bite is seldom 
so dangerous as that of the other snakes which 
have only large fangs in the upper jaw. The 
species of this division are exceedingly nu¬ 
merous and difficult to determine, and they 
have lately been divided into many genera, 
which it would be tedious to characterize in 
this sketch. Those that live on the ground and 
take to the water for protection, or to catch 
their food, have generally a cylindrical form
