In this series are 64 males, ranging in length of head and body (the 

 tails being mutilated) from 54 mm. to 132 mm.; the largest perfect 

 male (63450) measures 303 (113 + 190) mm. Of the 37 females the 

 smallest measures 96 (34 + 62) mm. and the largest (42206) 260 

 (100+160) mm. It is an unfortunate fact that the majority of these 

 agamas, particularly the males, lose their tails; the older and larger 

 the Hzard the less likely it is to have a perfect caudal appendage. 



As already mentioned, if we regard the agamas from the extreme 

 west coast as typical of the species, then the males of this series are 

 not entirely typical. They are characterized by strongly spinose and 

 mucronate scales, even on the vertebral line, a moderate but distinct 

 nuchal crest, a flattened but still rounded tail wliich lacks a dorsal 

 keel. Praeanal pores in these males range from 9 to 16 with an average 

 for 61 males of 11.7 pores. In young males (41365 for example) 

 the mucro is sometimes indistinct but can be seen with a strong lens; 

 in young females (41916, 41921, etc.) they may be so poorly developed 

 as to be fairly considered lacking, Females do not differ appreciably 

 from those referred io A. a. lionotus or paratype females of A. a. 

 usamharae but do differ from a female A. a. planiceps (M. C. Z. 18276 

 from Pungo Andongo, Angola, identified by Boulenger) and females 

 of -4. a. caudospina in possessing mucros to most of the dorsal scales.
