Quast 1948 Journal 112 June 11 La Laguna, 6200' ft, Sierra de la Laguna, Baja California Murray caught one Sorex ornatus lagunae last night in a Museum special mouse trap baited with walnut and set in a bank along side of stream near camp. Fifty Museum special mouse traps baited with walnut and set along running water in center of field caught nothing and no traps were disturbed. Traps were set in stream bed usually on damp ground within two feet of the running water. No appreciable cover was found along the stream bank, that the existing being formed by a few large-leaved composite plants. Shot four Vta thalassina (#343-346 incl) this afternoon. They were found on large granite boulders in canyon wall at stream exit at east end of La Laguna. Most of these lizards were seen in the rocks at the end of the flat, and none in the canyon proper. One was seen in isolated granite boulders in center of eastern portion of La Laguna. Willows grow in several small patches along the two streams (springs) in the southern side of the eastern portion and in the canyon exit in the east. The canyon exit contains the largest amount of running water in the area and the stream flows over small falls and into pools for at least 300 yds down the canyon. Willows grow in patches through the canyon at the edge. [See map pg. 117]
