1 have re-examined all the specimens in the British Museum in 

 the ligbt of the remarks recently made by Prof. Barboza du 

 Bocage (Herp. d' Angola et du Congo, pp. 102 & 104) and by 

 Dr. Mocquard (Bull.Soc. Philom. [8] ix. 1897, p. 9), and although 

 I admit the possibility of several species being confounded under 

 the name of G. smythi, I am unable to separate them into two 

 by means of the characters pointed out by these authorities. 

 This is obvious from the following tabulation of the shields and 

 scales in the specimens examined by me : —

Mocquard gives 19 as the number of scales in O. ornata=fureata, 

 but the types of both these supposed species are described as having 

 only 17. A much larger material than was accessible to Bocage, 

 Mocquard, and myself is required before the variations of the 

 forms of this genus can be properly understood.
