Considering that a portion of Black Gap contains extensive limestone outcrops, these heard frogs may have been S. marnockii - TEL]

Provides a good summary of taxonomic history as well as photos of an adult and habitat in the Chisos Mountains. - TEL]

"Collections in Big Bend National Park in 1957 and 1958 yielded several additional specimens and indicated that the population is still quite strong.  It appears to have disappeared from the Stockton Plateau, however."

" We recognize this specimen as E. marnockii based on phenotypic similarity to individuals from the Edwards Plateau, following Milstead et al. (1950. Texas J. Sci. 2:543–562). This species had previously been heard calling in canyons at this locality; however, collection attempts over the last 60 years have been unsuccessful (Jameson and Flury 1949, op cit. and T. J. LaDuc, pers. comm.). To the best of our knowledge, only two other voucher specimens of this species have been collected in Presidio Co., both in 1968 from San Esteban Lake (19.3 km SE of Marfa, Texas; Texas Cooperative Wildlife Collections [TCWC] 26056, 26057), ~74 km SW of Camp Holland. The next nearest locality of this species is from two specimens collected in 1964 from Musquiz Canyon, SE of Fort Davis (likely where it bisects the Arkansas and Puertacitas Mountains; TCWC 81651, 81652) in southeastern Jeff Davis Co., ~88 km E of Camp Holland. These four TCWC specimens are currently catalogued as E. guttilatus."  Unfortunately the authors fail to mention the kind of rock substrate their specimens were found upon, since S. guttilatus may merely represent a color phase of S. marnockii found on igneous substrates rather than limestone ones. - TEL]

only trivial characters; it is believed, however, that the differences noted characterize a well-isolated population, separated by some 250 miles from the range of marnockii, and that these differences indicate that a distinct form is in process of evolution.
