Caught a juvenile Pseustes at 1602 m in leaves beside trail at xxxx/025m (just before bridge over Saltito).

The Liebman's saw a subadult Felis concolor last night. June 9 May Today Rodolfo Peralta found at noon a Bothrops asutus: 296+32mm, 22.0g. It contained a Heteromys, freshly swallowed head-first; SV 102 mm, tail 95 mm, max dia (head) 15 mm, 28.5 g. Dave Hardy and walked out the CE's
