18/1.] DR. J. ANDERSON ON INDIAN HKl'TILES. 155 



The posterior dilatation is 3" 3'" in diameter, and 3" 5 " in length. 

 The greatest external length of the abdominal plates is 7", and their 

 narrowest portion measured antero-posteriorly is 2" 6'". The in- 

 guinal plates are triangular, and in close contact with the abdominal 

 ones, and form a zigzag suture with each other : their greatest 

 length is in the mesial line, 4" 3" ; and the greatest breadth across the 

 anterior margin of one is 4" 5'". The odd and inguinal sutures are 

 marked with many raised lines bearing tubercles in some cases. The 

 lines are rather weak for the size of the specimen. The abdominal 

 plates are marked with lines of the same character as in the former ; 

 but the tubercles are much more numerous, especially on the external 

 and internal portions, and on the former in particular they form 

 well-marked, closely packed, shining papillae. 



There is a well-marked swelling anteriorly on the mesial line, with 

 a slight depression on either side externally and posteriorly ; the 

 vertebral line is concave behind the swelling within about two inches 

 of the end, where it is again convex. 



The general surface is not so rough compared with the great size 

 of the animal as in T. gangetieus. 



The wavy raised lines and the tubercles that they bear are more 

 sparse and coarser on the vertebral line, and along the lines of the 

 sutures of the costal plates, and not merely on the vertebral line, as 

 observed by Theobald. 



The chief differences that separate it from T. gangetieus are the 

 less developed character of the osseous portion of the sternum, and 

 the relatively finer character of its sculpturing on both aspects. The 

 toes are broadly webbed, and the claws are strong conical structures, 

 the largest being about one inch in length. 



T. jeudi, which is doubtfully assigned by Dr. Gray to the island 

 of Java, was described from a skull in the British Museum. This I 

 have carefully compared with the skull of the specimen from which 

 the foregoing description is derived, and cannot detect any characters 

 by which to separate the two. 



Varanus lunatus, Gray ; Gthr. I. c. p. 66. 



This species appears to be common in the Agra district. The 

 adults are olive-brown above, yellower on the tail and underparts, 

 and very obscurely banded on the sides, with a darker tint of the 

 same colour as the upper parts, where the banding is scarcely per- 

 ceptible. It is more marked, however, on the tail. Some of the 

 specimens are black, spotted on the sides and back in almost the 

 same way as V. draccena. The largest specimen is 45^ inches, of 

 which the tail measures 26". 



These lizards are much infected by ticks about the anal region, 

 neighbourhood of head, and body generally. 



Varanus flavescens, Gray ; Gthr. 1. c. p. 65. 



I have received a young specimen of this species from Agra. It 

 is light yellow, banded with brown.
