Lou, James 1974 Chilomysus sericus 21 March El Sombrero Trailer Park, La Paz, Baja California Sur, 80 for seven individuals have been found by us on our trip to Baja, six here in Bed Papafuss' study area (see journal of 18 March) and the first one 9.3 mi W San Gregorio Parador on Mex. Hwy 1, Baja Calif Norte, (17 Mar). All but one have had dark dorsal bands with the light-colored scales tinged lightly with orange; the ventor is cream- colored. One individual found yesterday, however showed much more darker orange color dorsally and extending laterally into the flanks. Also, the dorsal bands are marked by being not solid, but variously broken into a network of brown and orange. This pattern is more evident posteriorly, with the anterior bands being solid brown, and the posterior-most bands being mostly orange dots surrounded by brown orange ground color - tail tip orange dots brown outline
