on their own axes so that the ridges lie anteriorly and posteriorly. 

 The teeth in the maxillary series are directed backwards, and present a 

 slight inclination inwards. The palato-pterygoid are directed straight 

 backwards, and the mandibular at first directed backwards, gradually 

 acquire a strong inclination inwards. Further, the maxillary array is 

 isodont in its greater length (i.e., has teeth of equal size). A few ot 

 the most anterior are, however, progressively smaller, and the two last 

 occurring after an interval are very much enlarged. These enlarged 

 teeth have been already figured in the second of these papers (Vol. 

 XVII, facing page 2), and are in this species intermediate between 

 those shown in figs. 1 and 2 of that paper. The palato-pterygoid 

 series are isodont, as are also the mandibular, excepting a very few 

 in the extreme forefront, which are shorter.

ADDENDA. 



Since writing the above I have the following remarks to add : — 



(1) Willey says it is called " Diya polonga " in Ceylon (Spol. 

 Zeylan. April 1906, p. 233). 



(2) My notes in Fyzabad last year are wonderfully similar for this 

 month. Of specimens actually measured, I had 16 varying from 9-J 

 to 12£ inches, 2 measured respectively l'-3" and l'-5f", 2 others 

 were l'-9^" and 2'-0f", and 1 was 2'-4^". 



(3) I am able to confirm this so far as Assam is concerned, for I 

 have had 6 females heavily eggbound this month (April) containing re- 

 spectively in abdomina 39, 44, 51, 53, 21 and 34 eggs of dimensions 

 showing that they would very shortly have been discharged. 



(4) In the administration report of the Government Museum, 

 Madras, for 1896-7 I notice a female laid 36 eggs in captivity on 

 the 26th of February 1897. 



(5) Apropos this remark I quote from last year's experiences in my 

 note-book 19th July 1906 — " I have had two hatchlings to-day, and 

 both moved very rapidly, did their utmost to escape me, struck out 

 viciously and repeatedly at a stick, and both literally jumped so as to clear 

 the ground without doubt more than once." Again 20th July 1906 — 

 "Another hatchling to-day jumped, and was most ferocious. I got 

 badly bitten in my endeavours to grasp it. Its incessant contortions,
