D. A. Good 1987 Journal Volcán Cacao, Parque Guanacaste, Costa Rica 23 August We've been at Casa Mango. Didn't find any lumps there. Didn't go out tonight - to bed ca. 7:00. Weather windy, some rain in morning + a spattering in late afternoon. 24 August The general tendency in the weather here has been to rain early in the morning + then be less likely to by lots morning. We therefore decided to wait until mid-morning before starting our outdoor activities today. Breakfast 6:00, then road, etc until 9:30 when we hiked up toward the top of the mountain. Our first encounter with a lump was (wonder of wonders) a snake (Rhadinidae?) on the trail up to the turnoff to the peak (1195 m elev.). We began looking in moss along the ridge to the top at ca. 1420 m, where we had found Nototriton before + slowly worked our way up checking moss along the way. Found a total of 5 Nototriton today as follows: 1) In moss ca. 4 ft off ground on vertical tree trunk. Moss temp: 17.6°C, air 17.6°C. Elevation 1475m. 2) In moss ca. 5½ ft off ground on vertical branch (from horizontal trunk ca. 6 inches below). Moss temp. 17.7°C, air 18.1°C. Elevation 1475m. 3) In moss ca. 5 ft off ground on vertical trunk. Moss temp. 17.0°C, air 17.1°C. Elevation 1580 m. 4) In moss on vertical aerial root ca. 4 ft off ground. Moss temp 17.4°C, air 17.4°C. Elevation 1580 m. 5) In moss ca. 12 ft off ground on vertical trunk. This was in the only recoverable handful of moss on a trunk that had been
