Freere, H. 1980 2 December (continued) Quebrada ~5 Km (air) NE Najitos, Piura Prox. Peru This is a fairly broad valley, bounded by loose hills and filled w/ low shrubs and trees and one "farm" at the NE end. We split into four groups and worked separately, from ~1000-1145. Saw many Deirodon guttulatus and collected 5 nice adult by mouse and with a pellet rifle. I got one small Tropidurus sp. on a small wooden coral beside an abandoned adobe hut a few hundred meters W. of the farm house. As John Bowlin's group returned to the cars from another valley to the E. of this one he spotted a Callopistes lying in front of a tunnel, near a small tree, at the W. upper edge of the valley. Almost missed it before it went in. I joined him, and we dug 'til ~1330, a total of ~7-8 m of trench, ~1m deep and .5-.7 m wide - difficult digging because wind blew it in almost as fast as we shoveled it out. About .5m down we ran into sea shells, pot shards, and (?) old goat dung. Also several skins of Amphibaena occidentalis ~3-5m down, seemingly fresh. Also
