spöts usually with a small white dot at their hind margin. 

 Below, the centres of the scales and plates are brown or 

 blackish, with yellowish white margins more or less broad. 

 In. the male specimens the dark colour appears as blackish 

 brown spöts on the middle of the ventral plates, forming 

 regular longitudinal rows of dark spöts on the light belly 

 and the under surface of the tail.

 bia, obtained by mr Nisser already in the year 1833,

It is with great hesitation I venture to describe these 

 specimens, now kept in the R. Natural Museum for nearly a 

 century, as a new species, but I am not able to find any 

 species described in the literature neither of this genus, 

 nor of the closely allied Oreosaurus, to which I can refer them. 

 Considering the species of Proctoporus described, my species 

 seems to be rather nearly allied to P. meleagris Blgr from 

 Western Ecuador, but the latter differs in having »inter- 

 parietal narrow not widened posteriorly, three occipitals, 

 eight rows of shields between the chin-shields and the edge 

 of the collar; collar-shields eight; thirty-four scales round 

 the middle of the body; three praeanal shields, eleven or 

 twelve feraoral pores on each side, two of which may be 

 termed prseanal. Black, upper parts minutely dotted with 

 whitish». None of these characteristics are to be found in my 

 specimens. 



In other respects they appear to be more allied to Proc- 

 toporus simoterus 0'Schaugn. which, however, is described 

 on an anomalous speeimen. The interparietal and the prse- 

 anal shields seem to be of similar shape as in that species, 

 but in other points, mentioned above, my specimens differ
