Natural history.—One female (QCAZ 3046) collected on 15 October 1995 contained two oviductal eggs. The sizes of these eggs are mm x mm and mm x mm; their volumes are mm^ and mm^ respec- tively. The same female had a body temperature of °C when collected (A. Quiguango and Juan M. Guayasamin, field notes, 24 February 1998). The smallest juvenile (QCAZ 719), collected on 17 May 1988, has a total length of 134 mm (SVL = 45 mm, TL = 89 mm). Distribution and ecology.—Stenocercus varius occurs at elevations of 1460-2200 m on the western slopes of the northern part of the Cordillera Occidental. It inhabits the upper valleys of the Rio Blanco and Rio Toachi (Pacific Drainage) in Provincia Cotopaxi and Provincia Pichincha (Fig. 19). The distribution lies within the Very Humid Premontane Forest and Low Very Humid Montane For- est. The mean annual temperature is 18-24°C and 12-18°C, respectively. The mean annual precipitation is 2000-4000 mm in both life zones. Individuals have been found on tree trunks, fallen logs, and rocks in partially cleared ar
