and the tibia is considerably longer than the skull. The wrist in 

 all reaches in advance of the snout ; but the tip of the fourth toe, 

 in three, reaches the eye, whilst, in two, it is in advance of the eye. 

 The digits are rather long, and laterally compressed. The fourth 

 finger is only very slightly longer than the third, and the fourth 

 toe than the third. The tail is somewhat slightly compressed 

 beyond the base, but afterwards it is round and tapers to a fine 

 point; it is about twice as long as the distance between the 

 snout and the vent. Six to twelve prseanal pores in the male, 

 with callose scales on the abdomen. 



OHve, mottled with brownish ; blue about the eyes and along 

 the labial line ; the throat more or less reticulated with bluish 

 lines. TJnderparts yellowish, but a few blue spots on the belly. 

 A young male is olive, but the body has brownish markings, 

 and bluish green on the head above, and bright blue below with 

 dark blue lines ; belly greenish yellow, mottled with blue ; tail 

 yellow at the base, olive distally, with about 18 brown bars. 

 Another male is entirely blue above and brilliant blue below, the 

 base of the tail yellow. 



The rosette of spines on the post-temporal region, the short, 

 but well-defined nuchal crest, with a rosette of spines on either 

 side of it, near its middle, are all absent in A. annectens, Blanf., 

 in which the lateral fold along the side over the shoulders is 

 also practically absent, but, if feebly present, it never presents 

 the small spinose rosettes that occur in the Arabian form. The 

 scales also of the body are smaller in the Abyssinian species, in 

 which there are 150 on the type around the middle of the body, 

 and only 119 in the Arabian species. 



A. adramitana is distinguished from A. cyanogaster, Eiippell, 

 and from A. nupta, De Kl., by its much smaller scales.
