During his stay at different stations of the Upper Nile and Bahr-El-Ghazal Provinces, 
for investigations on blood-parasites, Dr. Morley Wenyon, of the Wellcome Research 
Laboratories, Khartoum, and the London School of Tropical Medicine, collected a number 
of reptiles, and, when returning home, was so kind as to pay me a visit in Vienna, on 
March 20th, 1908, where I had the pleasure of examining the very interesting collection of 
reptiles he had made in the Sudan. 1 am very grateful to him for the gift of the whole 
material, to which the following notes refer : — 
Turtles 
Cyclanorhis oligotylus, Siebenrock 
A fine young specimen from Nasser, Upper Sobat. It is coloured rather similarly to 
the larger one brought home by myself from Khor Attar. 
Lizards 
Acjama hartmanni, Peters 
A male from Taufikia; total length 208 mm., tail 133 min. I must confess that I can 
no longer have doubts about the occurrence of this species in the Upper Nile Valley, although 
I expressed such in my publication on the Sudan Reptiles {Sitz. Ber. Akad. lUm. lUtcre, 
Vol. CXVI., 1907, page 1836). The specimen before me shows all the characters that 
distinguish the typical specimen in the Berlin Museum from A. colonorum ; the snout 
being without an elongate, enlarged and longitudinally-keeled scale on the median 
elevated crest; nasal short, nostril in the middle, pointing backwards; spines around 
the ear very few and minute ; lateral scales not smaller than dorsals, less distinctly 
mucronate. 
Brown above, with a yellow median line on the back and a row of yellow, elliptical, 
dark margined spots on each side ; similar, but much less distinct, spots below them. 
Habit more slender than in .1. colonorum. Prseanal scales, 10. 
Agama colonorum, Daudin 
A male (October 14th, 1907) and a female (August 27th, 1907), from Wau (Bahr-El- 
Ghazal) ; similar to my specimens from Mongalla and Gondokoro. The species has been 
already recorded from the Bahr-El-Ghazal (Meshra-El-Rek) by Heuglin. 
Varaniis niloficur, Laurenti 
A young specimen from Wau (September 20th, 1907). 
ilahuia quinquetcrniata, Lichtenstein 
Two males and a female from Wau, Bahr-El-Ghazal Province. Scales round the body, 
36-38; preefrontals in contact in all specimens. Throat of adult male deep black. 
Dr. Wenyon has kindly given me the following notes regarding the adaptation of this 
lizard to the colour of its surroundings ;— 
“ The male lizard [Mahuia quiuqiietieniuta) is curiously marked, having the anterior 
half of its body green, dotted with black spots, while the posterior half, including the tail, is
