Seib, R. 1985 Nopolo to Isla Catalana, Baja California Sur, Mexico 14 May and a complete nuchal collar out might be an Eridiphos. We also picked up 5 tuberculate Phyllodactylus. Slept at about midnight. Isla Catalana to Nopolo, Baja California Sur, Mexico 15 May Antonio woke me up at 630 getting to leave. We left. Arrived back at Juncalito at 1015. Our total species list for the island is: Uta Lepidophaps (1) Cnemidophorus (tigris) night snake (1) Phyllodactylus Crotalus (2) enyo catalinaensis We drove straight to the El Presidente at Nopolo and ate breakfast. I worked on relieving my headache, wrote notes, cataloged, preserved, showered and slept. It was windy all day and the wind blew in a cloud cover. At night we drove about 27.5 mi S of Loreto, finding four snakes, all DOH: Pituophis chiloneuscos, Hypsiglena and Trimorphodon. The chiloneuscos looks very different from the cinctus S of La Paz: many small bands. Went back to the hotel and immediately passed out.
