Note on a specimen of Prosymna sandevalli 
{Smith). 
By Lewis Henry Gough. Ph.D. 
A specimen of Prosymna sundevalli (Smith) received on 
■28th February, 1908, from Pretoria cads for a few remarks. 
The specimen is 32 cm. long, of which three belong to the 
tail ; the proportion of the tail to the body is thus smaller 
than that of the specimen recorded by Boulenger Cat. of Snakes, 
Vol. II., p. 248. The coloration is also remarkable, differing 
from the normal. The upper surface is a bright chestnut 
brown, each scale edged with darker, the vertebral row being 
bright yellow ; several of the scales have white spots, the 
outer row is almost all white, the second row being white with 
a brown spot at the base of each scale. 
The frontal and parietal s are brighter chestnut than the 
rest of the body, a dark band runs from eye to eye in front 
oi the frontal. There is no trace of the two rows of brown 
spots along each side of the back. 
The scales of the head differ in following points from the 
normal ; the frontal is only just as long as the parietals, and 
there are only six upper labials instead of seven or eight. 
Ventrals 161, Anal 1, Sub-caudals 25. 
The other two specimens of P. sundevalli (Smith) in the 
Museum (taken at Krabbefontein, Zoutpansberg) are normal 
in coloration and in the proportion of the frontal to the 
parietals, but vary in the same way with regard to the labials, 
having but six.
