groin, lateral and usually high, and often conspicuous and protuberant. The elevation or flatness of the lumbar glands seems to be due to individual variation; living specimens in the field had conspicuous and protuberant, or non-elevated, indistinct lumbar glands. Lumbar glands are not to be confused with inguinal glands, which are roundish, often yellowish, sometimes diffuse, lateral but low, often inconspicuous, and usually not protuberant. Inguinal glands occur in the genus Microbatrachylus and in some species of Eleutherodactylus, and have been described as flat, or low, or small, or indistinct for most species of Syrrhophus.

For financial assistance with field work I am grateful to Rollin H. Baker, and those individuals who administer the Michigan State University Development Fund and the Bache Fund of the National Academy of Sciences (Grant No. 463). I am grateful also to J. Keever Greer, Donald F. Switzenberg, and Rudolph A. Scheibner for aid in the field, to Edward H. Taylor, James R. Dixon, and William E. Duellman for profitable discussions, and to Thomas Sweringen for figure 1. The specific name alludes to the habitat (Latin, saxatilis = found among rocks).
