KUNGL. SV. VET. AKADEMIENS HANDUNGAR. RAND 47. NO 6. 13 



Boulenokr had only one type specimen and that one had »nine or ten upper 

 labials»; in the present specimens eleven is the usual nuniber, in one it is, Iiowever, 

 only nine. There is sometimes one, sometimes two elongate scales on the middle <>t 

 the snout. In the specimen from Guaso Nyiri there are about 70 scales round ili<- 

 body, but the specimens from Therä have smaller scales still, counting up to about 

 80 in nuniber around the body. 



Although, as far as can be judged from the material at hand, there are some 

 small differences between these Ägarnas and the type of A. lionotus there is certainly 

 a closer relationship between them than with a ny other Agama. There is, however, 

 on the other hand no very great difference between these smooth-backed Ägarnas 

 and the Ägarnas of the dorice type, and intergrading links may possibly be found if 

 a large material could be collected. To some degree the specimen from below Chanler 

 Falls constitutes such a link. 



The male specimen from Guaso Nyiri below Chanler Falls has 11 praeanal pores. 

 Its length of head and body is 133 mm. length of tail 253 mm. tibia 35 mm. hind- 

 foot 41 mm. 



The type locality of A. lionotus is recorded to be »S. E. of Lake Rudolf». At 

 the localities where the present specimens have been collected several other animals 

 of other groups have been found which are known to have their habitat in the count- 

 ries bordering Lake Rudolph. There is thus from a zoogeographical point of view 

 only in accordance with other discoveries made by this expedition to find A. lionotus 

 as far south as at Guaso Nyiri. 



Varanidae. 

 Varanus ocellatus Rupp. 

 Blgr.: Cat. Lizards, B. M. II, p. 308. 



The first specimen of this kind was found 8 /a south of Guaso Nyiri on the 

 steppe at Lekiundu river in a hole that it had dug under a stone. 1 held it with a 

 stick, lifted the stone and caught it by the neck. Another specimen was seen in the 

 thornbush country north of Guaso Nyiri. It had climbed up in a bush and was shot 

 there 17 ,3. This latter specimen looked very thin. 



This species belongs to the fauna of Northeastern Africa but has been recorded 

 as far south as in Usambara. 



Varanus niloticus Lin. 

 Blgr.: Cat. Lizards, B. M. II, p. 317. 



This lizard was seen several times 011 the banks of Guaso Nyiri below Chanler 

 Falls, and a specimen was also secured there with a shot. 

 Very widely distributed.
