YOUNG CllOCODILIANS IN CAPTIVITY. 171 



length of its snout is from two and two-thirds to three and 

 one-third its basal width (Boulenger). 



In the specimen figured in PL I., fig. 1, which 

 measures 28'25 inches, and from which the following 

 descrfption is taken, the length of the snout is 2' 75 times 

 its basal width. The snout is very long and slender, its 

 tip is slightly expanded — becoming contracted at the 

 notches ; immediately in front of the latter are two short 

 ridges running obliquely backwards and inwards. The 

 snout is laterally expanded about the level of the fifth or 

 sixth maxillary tooth, contracting again nearer the head. 



The colouration of the upper surface is a dark olive, 

 more marked on the head and snout. 



There are four small post-occipital scutes, the outer 

 pair of which are somewhat anterior to the inner ones. 

 Behind these are four large nuchals in a square with a 

 smaller pair immediately behind, making it difficult to 

 decide whether they are nuchal or dorsal. 



Continuous or sub- continuous with these are about 

 twenty-eight transverse rows, the widest with six in a row. 

 The dorsal armour is very regular. The first seventeen 

 rows of the thirty-four or thiity-five forming the tail are 

 undivided, the remainder form the serrated crest. 



There are four, somewhat indistinct, transverse dark 

 bars crossing the back, and two or three similar bars 

 sloping obliquely downwards and backwards, along the 

 sides ; in addition to which there are some dark scattered 

 blotches. Three or four heavy dark bars cross the tail 

 transversely, while the sides of it are heavily splashed 

 with black. The under surface of the throat is white, that 

 of the abdomen white also, with black marblings on each 

 shield, and the under surface of the tail is dark brown 

 with white patches. 



The lateral surfaces of the jaws shew a few hazy
