78 COLLECTION OF OPHIDXA IN MUSEUM 
Chlorophis (Green Snakes). — In the series of this genus 
from Kakumega we have some interesting irregularities. 
In the ‘ Catalogue of Snakes,’ Yol. II, the description of 
the labials in emini is 4 nine upper labials, 4th, 5th, and 6th 
entering the eye.’ In hoplogaster ‘ eight upper labials, 4th 
and 5th entering the eye.’ As will be seen from the data 
of one of our specimens of emini (I 88), there are nine labials 
on one side of the head and eight on the other ; again, in I 39 
there are nine and seven, whilst in two undoubted specimens 
of emini there are seven on both sides. In I 89 on the right 
side (7 labials) 3rd, 4th, and 5th enter the eye, the left side 
is normal. The same thing occurs in I 37. Andersson 1 refers 
to a similar scalation in a specimen of emini he obtained at 
Khartoum, but in his snake it is the left side that has eight 
labials, the right being normal. The two specimens, I 42 and 
I 43, might be referred to either species — emini or hoplogaster. 
In the number of ventrals and sub-caudals they incline to 
emini, but in labials to hoplogaster, for in I 42, 4th and 5th 
enter eye on the right side ; 4th, 5th, and 6th on left. I 43, 
4th and 5th enter on left side, and the right side is damaged. 
Just on going to press I have received from Mr. Turner nearly 
fifty examples of these two species from the Yala river. These 
I have carefully examined. 
Thirty-two of these were C. emini, of which seventeen were 
normal on the basis of two labials entering eye ; the last 
specimen should be referred to hoplogaster were it not that 
the caudals number 112.
