band along the side ; this band is only one scale wide and vanishes 

 on the tail. Tiiroat and under surfaces white." One Nairobi 5 

 specimen has longitudinal striations on whole of under surface. 



A female taken on September 20th, 1918, at Lumbo held four 

 eggs 8x6 mm. Another female taken at Pai'klands, Nairobi, on 

 22.vii. 15 had four eggs 8 or 9 by 6, irregular in shape and 

 containing small embryos. 



It seems to me that the Lumbo specimens have much longer 

 tails than the B.E.A. and G.E.A. specimens. The habit of the 

 latter is much stouter both in body and thickness of tail. Their 

 colour is much darker also. Unfortunately the series from 

 Nairobi is not available, with the exception of twelve specimens ; 

 the largest of these measures 80 mm. in head and body and 

 122 mm. in tail, which is intact. Another $ 55 + 165 mm., d 55 

 + 163, 2 55 + 162. 



The Lumbo specimens were found rushing about on sandy 

 ground, which is very sparsely grown with clumps of grass. 

 Naii'obi specimens on the other hand were collected in grass up 

 to one's knees, either on the plains or near the Parklands 

 Forest edge. They clambered with great agility about the tops 

 of the grasses. Possibly the different kind of country where 

 they were obtained explains the dijSerences in appearances and 

 the relatively shorter tail length of the grassy upland forms. 



Spiders, a little grass (probably accidentally introduced), and 

 parasitic worms were found in the stomach of a male at Lumbo. 

 The worms have been identified as immature Physaloptera.

Two males only obtained at Dodoma, 8. xii. 18. The larger 

 measured 8| inches (92"128 mm.) and the smaller just under 

 Sg inches (90'113 mm.). Colour during life : — " Pale bluish, with 

 faint coppery traces of lines on the back. Neck striated with 

 bright yellow and blackish lines. Preserved specimens do not 

 show these so well." Both specimens were living beneath boulders 

 on rocky kopjes. 



Mabuia varia (Peters). 



Blgr. Cat. Liz. iii. 1887, p. 202. 



Twenty-seven specimens collected at Nairobi, Longido West, 

 Kongwa, Morogoro, Duthumi, Lumbo, and Delagoa Bay. Was 

 also seen at Mbunyi and Kahe. The largest specimens came 

 from Nairobi, though Lumbo specimens had longer tails than 

 either B.E.A. or G.E.A. specimens.
