Digestive Tract. — When in the field Mr. Lang observed that in 

 a female 1360 mm. long that "The intestine measured 1080 mm. There 

 is no caecum. The stomach is practically divided in two sections : one 

 section is surrounded by strong muscles and resembles a gizzard; it 

 was filled with small stones (the largest 5 mm. in diameter) and heads of 

 ants it had eaten. There is towards the middle a large, roundish, raised 

 gland patch; the rest of the stomach is provided with folds; and has 

 been preserved in formalin. Towards the pyloric end is a raised portion 

 that looks like a sort of stopper, and as it projects far into the stomach it 

 certainly is of some assistance in grinding the food along its roundish 

 folded surface." 



Anal Glands. — " On either side of the anus are two ducts from which 

 a strongly smelling, white pasty excretion is given off on pressure from 

 the outside/' according to Mr. Lang. 



Reproduction. — Two fetuses were found in specimens of gigantea 

 measuring 1350 and 1365 mm. in total length. One of these fetuses 

 taken November 28, measures 240 mm. in total length. The other (Plate 

 XXXIV, figure 1) removed on December 9, measures 290 mm. 



Scales, Defense. — "The scales on the sides hang very loosely 

 down when [the animal] stretched out," wrote Mr. Lang. "If one tried 

 to unfold the living specimen it would suddenly glide its tail along its 

 side, often with such force as easily to bend over a native-made knife of 

 3 mm. thickness stabbed in its side." 



Burrow. — A burrow of this species, photographed by Mr. Lang at 

 Babeyru, is shown in Plate XXXIV, figure 2.
