CYLINDROPHIS MACULATUS. 179 



scales in the anterior part of the body, and become somewhat larger posteriorly ; anal bifid ; 

 subcaudals nan-ow, simple. 



The Cylindrophides are burrowing animals, only occasionally found above ground ; they 

 feed on insects, worms, and small mammals living in earth-holes. 



Width of the interocular space more than the length of the snout . C. rufus. 

 Width of the interocular space equal to the length of the snout . . C. maculatus. 



Note. — Mr. Jerdon (Journ. As. Soc. Beng. xxii. p. 527) mentions two Cylindrophides occurring in the 

 Peninsula of India, and adds the following characters (!) : — 



" C curticeps. Differs from C. maculatus (? ?) in its shorter, more triangular head, &c. &c." 



" C. macroscelis*. Differs from both in the much larger scales." 



Very probably these new species of Mr. Jerdon will turn out not to be Cylindrophides at all.

Head depressed, broad, short, its width between the eyes being more than the length of 

 the snout. Vertical shield as broad as long, subtriangular, not larger than a supraorbital. 

 Ventral shields scarcely larger than the scales of the adjoining series. Scales in nineteen or 

 twenty-one series. Ventrals 184-200 ; subcaudals 6-9. Brown or black : belly with irregular 

 white cross bands, extending more or less up the sides ; the first of these cross bands is behind 

 the angle of the mouth, frequently extending near to the median line of the back, and 

 forming an interrupted collar. Sometimes a white spot on each frontal. This spot, the 

 collar, and the lower part of the tail are bright vermilion during life. 



This species attains to a length of 30 inches, and is found in many islands of the East 

 Indian Archipelago (Java, Borneo), in Gamboja, at Singapore, and on the coast of Tranquebar. 

 The differences in the number of the scales and in the coloration do not depend on the 

 various localities, and therefore are not indicative of different specific forms.
