The first plethodonid salamander is reported, the species Ambystoma rosaceum is discussed in greater detail than before, and two subspecies are recognized. Spea is elevated from subgeneric to generic rank, and S. stagnalis Cope is removed from synonymy and is recognized as a subspecies of hammondii. The species listed include the following: 2 salamanders and 19 anurans (1 Scaphiopus, 2 Spea, 9 Bufo, 1 Elentherodacttjlus, 2 Hyla, 3 Rana, and 1 Microhyla). Reference is made to various habitats that are associated with elevations arising from lower deserts and extending into the western mountains. The role played by the dry and wet annual cycles is also noted. This is the third report on the herpetology important studies are cited in the first of this of western Chihuahua (Tanner 1985 [1986], series (Tanner 1985 [1986]).
