524 Dr. A. Giinthcr on Beptiles and Batrachians 



Mabouia striata, Ptrs. 



Two specimens from Uganda (alt. 3800-4500 feet). In 

 both the snborbital scute is entirely excluded from the labial 

 margin ; also the hind leg is conspicuously shorter than in 

 typical specimens, not reaching the axilla ; so that I enter- 

 tain some doubts as to the propriety of identifying these 

 specimens with Peters's species. 



Chamcpsaura tenuior, sp. n. (PI. XXI. fig. B.) 



This species is conspicuously more slender than its con- 

 geners, especially the head and snout are narrower and longer. 

 Both the vertical as well as the single posterior frontal are 

 elongate, nearly twice as long as broad ; otherwise there is 

 great similarity between this and the other species. The 

 fore limbs are about as long as tlie orbit and without claw ; 

 the hind limbs are not quite twice as long as the fore limbs 

 and provided with a single claw. Thirty-six scales between 

 the ear and vent ; twenty-four round the body. Back of the 

 trunk with a pair of narrow parallel brown lines. 



One specimen from Kampala, Uganda, 22\ inches long, 

 of whicli the tail takes 18. 



Chamceleon senegalensis, var. Icevigata, Gray. 



Two specimens, one from Kavirondo (alt. 3900-1000 feet), 

 the other from the foot of Mount Ruwenzori (5000-6000 feet), 

 obtained together with the following species. 



Chamceleon Elliott, sp. n. (PI. XXI. fig. A.) 



This species is represented by several specimens from the 

 same localities as the preceding, and is apparently more 

 common. The upper surface of the head distinctly concave, 

 the superciliary edges and the canthus rostralis being raised, 

 and coarsely granular. Three rows of enlarged granules com- 

 mence about the middle of the interorbital space, and converge 

 to form a distinctly elevated occipital crest, covered with 

 tubercles. A longitudinal row of small tubercles traverses 

 the temporal region. No rostral appendages ; no occipital 

 lobes. Body finely granular, with small tubercles irregularly 

 scattered. A continuous row of tubercles along the middle of 

 the back and anterior portion of the tail, forming a low crest. 

 A gular-ventral crest formed by pointed tubercles. No tarsal 

 process. Scales on the side and upper surface of the head 

 and of the temples small, flat. Tail as long as, or rather 

 shorter than, the body and head. Frequently a whitish line
