 1883, p. 28, from Central Madagascar, is no doubt very near to, and 

 probably only a variety of, P. laticauda. The only difference I can 

 find, from the very short description, is the presence of large round 

 black spots edged with light blue at axilla and groin.

Snout once and a half or once and two thirds as long as the 

 distance between the eye and the ear-opening, twice the diameter 

 of the orbit. Eostral generally without median cleft ; nostril 

 pierced above, and bordered beneath by the first upper labial ; eight 

 or nine upper labials ; seven or eight lower labials ; chin-shields 

 eight, scarcely distinct from the surrounding scales, which are quite 

 or almost as large ; generally a single scale between the naso- 

 rostrals. Vertical diameter of the ear-opening about half the 

 diameter of the orbit. Dorsal scales smooth, or very feebly keeled 

 on the hinder part of the back. Ventral scales strongly keeled. 

 Femoral pores twelve to fifteen, the number being generally thirteen. 

 Tail depressed, considerably narrower than the body; segments 

 distinct, limited by a row of larger scales, composed each of seven 

 or eight transverse rows on the side, eight or nine on the upper 

 surface ; scales on the upper surface of the tail feebly keeled, those 

 on the lower surface strongly keeled, larger, subequal, not trans- 

 versely dilated. Colour much as in A. laticauda ; the lateral blackish 

 band is constantly bordered inferiorly by another pure white band, 

 and it extends along each side of the tail.
