pores in these males range from 11 to 15, with an average for 45 males 

 of 12.7 pores. As is the case with A. a. agama, while the pores are 

 usually in a single series, occasionally a more or less developed second 

 row appears, but these are not included in the counts. 



One adult male (41908) from Fort Hall is so smooth that it compares 

 well with paratype males oi A. a. usamharae; in life, however, it 

 probably had the red, or reddish orange, head of the lionotus race 

 instead of the carmine one of the Usambara form. Writing from the 

 Guaso Nyiro camp, Roosevelt speaks of "the bright blue-green 

 lizards with orange heads." (African Game Trails, p. 315.)

As already mentioned, I may or may not have been correct in 1920 

 in referring caudospina to the synonymy oi flavicauda; until the types 

 oi flavicauda can be examined I prefer to adopt an attitude of caution 

 and recognise caudospina as distinct. From Lonnberg's remarks as 

 to the differences between his immature agama from Soy and typical 

 lionotus it seems certain that it should be referred to caudospina. 

 Angel's description of the coloration of his Naivasha lizard leaves no 

 doubt that it is caudospina; he states that the two Mount Kenya 

 specimens agree with it. 



In the Smithsonian series are seven males, ranging from 99 to 123 

 mm. in length of head and body; the tails of all seven are mutilated. 

 Of the seven females the smallest measures 19G (80 + 116) mm. and 

 the largest uninjured is 277 (112 + 165) mm. It might be added 

 that in the collection of the Museum of Comparative Zoology there 

 are even larger examples of both sexes, a male (M. C. Z. 8201) from 

 Guaso N^aro is 132 mm. in body length, and a female (M. C. Z. 

 1798) from Loita Plains is 222 (100 + 122) mm. even with the tip of 

 the tail lacking.
