back in the body than ordinary, these snakes may be recognised externally by the 
thickening of that region. The figured species (Adeniophis intestinalis ) is an 
extremely elongated and slender snake, inhabiting Burma and the Malayan Islands, 
and attaining a length of 2 feet. It is generally brown above with a yellowish 
black-edged line running down the middle of the back, and a nearly similar one on 
each side of the body; the under-parts being banded with yellow and black. 
Craits Although the native name crait applies properly only to a single 
member (Bungarus cceruleus ) of this genus, it may be conveniently 
extended to include the whole of the eight species, which range from India to the 
south of China, five occurring in India and Ceylon. Closely connected with the 
BANDED ADDER, OR RAJ-SAMP ( J Hat. size). 
resplendent snakes by the genus Hemibungarus, in which a solid tooth is present 
behind the fangs, the craits have from one to three small solid teeth behind these; 
and the smooth scales are arranged in thirteen or fifteen rows, with the middle row 
of the back larger than the others. The head resembles that of the last genus in 
being imperfectly distinguished from the neck, as well as in the size and number of 
its shields; while the small eye has a similar round pupil. The tail is of moderate 
length, or short, with the shields on its lower surface arranged in either a double 
or single series. The banded adder ( B. fcisciatus ) belongs to a group in which 
the shields on the lower surface of the body are very large, and broader than long; 
those of the tail being arranged in a single series. The species is distinguished 
by the presence of a distinct ridge along the back, by the obtuse extremity of 
the tail, and by the front temporal shield of the head being scarcely longer than
