Demarara to the Paraguay and upper Amazons 
15351, 7, 100-157 mm., creek, Rio Morona, Allen, October, 1920. 
15352, 1, 187 mm., Contamana, Rio Ucayali, Allen, August, 1920.

17831, 1, 94 mm. without caudal, Iquitos, Morris, 1922. 
The Cashiboya specimens have three distinct areas on supraoccipital and inter- 
orbital where radiating lines run into vermiculations. In this respect Pearson, 
1924, finds that his two specimens from Lago Rogoagua, Bolivia, differ from them, 
and that the dorsal vermiculations do not radiate from a center. The ventral 
surfaces of his specimens are vermiculated, sometimes breaking up into spots.
