From San Jose. Dr. Van Patten. 



This is a large species, being about equal to the A. edwardsii of Jamaica. It 

 is one of the most elegantly colored among the species of a beautiful genus. Its 

 affinities, as already pointed out, are to the A. squamulatus, Peters, which is very 

 near the A. laticeps of Berthold.

 Three specimens from Old Harbor. Color in life blue and brown. This animal 



haunts sunny spots on the edge of the forest.

 Specimens from Talamanca and San Jose. 



Abdominal scales small, flat, smooth; tail cylindric, with similar scales. Dorsal 

 scales smaller than ventral, pavement-like, very weakly keeled, graduating into 

 those of the lower part of the side, which are smaller. Head moderately elongate; 

 width between anterior margins of orbit equal length of muzzle from same point, 

 measured on the side. Interrugal concavity of the front well marked, occupied 

 by very small scales, much less than those of the rugae, in nine rows. Scales 

 between rug© and canthus large. Two rows separate the superciliaries, which are 

 separated by three or four rows from the occipital. Five rows of loreal scales. 

 Six smooth scales in the supraorbital disc, three inner large, transverse, the three 

 outer longitudinal. Four rows of infralabials medially; nostril surrounded by 

 small scales. Auricular meatus one-half eye-slit. 



Limbs long, toes slender, the dilatations well marked. The fore limb appressed 

 reaches the groin ; the hind limb extended attains the end of the muzzle. Fan 

 little developed.
