EAST AFRICAN LIZARDS. 141 



Many specimens are infested with a small acarid {Pterygosoma 

 againce) beneath the ventral scales. A new nematode {Oochoristica 

 agamce) * was found in several. 



Agama flavicauda (Werner).

Several specimens in the Nairobi Museum were collected by the 

 writer at West Kenia (23. xi. 1 5). A large male measures 8| inches 

 (100'120 mm.). These specimens were taken in the thatch of 

 a pig-sty, and in. an isolated pinnacle of earth where they had 

 taken up their abode in the holes excavated by Sand-Martins, 

 as well as in natural crevices. There are also specimens in the 

 Museum collected by Mr. Allen Turner at Kegamaia, near 

 Mt. Elgon. 



There can be no doubt that Agama caudospina recently 

 described by Meek from Elementeita, B.E.A., should be relegated 

 to the synonymy of this species. Werner's description was based 

 on a single male of unknown locality. Both names are very 

 descriptive of this species, which is quite unlike any other Agama 

 collected. 



Agama lionotus (Blgr.). 



Blgr. P. Z. S. 1896, p. 214, pi. viii. 



Thirteen specimens from Voi, Mbunyi, Longido West, and 

 Dodoma. Was also seen at Kahe and Kongwa ; there are 

 specimens in Nairobi Museum collected by the writer near the 

 Kedong Valley. 



The type specimen from S.E. of Lake Rudolph, as well as 

 specimens from Mt. Kenia and Ngaya (south of Lake Victoria), 

 B.E.A,, which are in the British Museum, were examined. 

 Arranging the specimens geographically from the type locality 

 southwards one finds a marked increase in the scale-rows. 



I draw attention to this for a purpose. These Dodoma speci- 

 mens are strikingly different in life to those collected elsewhere. 

 The throat of the males from other localities was invariably
