Examples of Lithodytes from Waco are not as brightly 
colored as those from the type locality, nor are the mark- 
ings of the upper surfaces as well defined. Miss Dick- 
erson? mentions Helotes specimens in which the superior 
surfaces were tinged with salmon-pink. As a rule, San 
Antonio and Waco examples of the same species, both in 
reptiles and amphibians, have widely different colors. 
Specimens of Holbrookia texana Troschel, and Sceloporus 
consobrinus B. & G., from the San Antonio district dis- 
play shades of red not exhibited by examples from Aus- 
tin northward. 
The following description was written in the field: 
(Baylor University Collection No. 5281, male, Waco, 
Texas, March 5, 1910.) Skin very smooth. Superior 
surfaces brownish gray with a few large brown spots 
having pale greenish centers. (These spots were very 
distinct in the living animal, but are now much faded, 
their outlines being barely perceptible. The animal was 
accidentally suffocated in the collecting can.) Outer and 
inner surfaces of limbs, bright yellowish green, this color 
extending along the side of the body to a point midway 
between the fore- and hind-limbs and forming conspic- 
uous patches. Below pale grayish dotted with white on 
the chest and throat as in pale Hastern examples of 
Engystoma carolinense Holbrook. Throat pale yellow- 
ish, a blackish line along the edge of the under lip. Bars 
on upper surfaces of the limbs present, but rather indis- 
tinct. Spots along side of body and head very conspic- 
uous, blackish brown in color. Spot in front of arm 
insertion pale in color but distinct. Spaces below dark 
spots under eyes and along upper lip, white. Iris bronze. 
Vocal pouch well developed. 
This specimen is only about half grown and the limbs 
are comparatively shorter than in larger examples. Total 
length, head and body, 1-13/16 in. The coloration, how-
