tically have to be touched to become alarmed. Snakes must find 
these little creatures easy prey at such times. A collection of adults 
that were taken on April 23, 1932, were clasped in pairs, and the 
females depesited eggs on Apri 25. On cool, rainy days captive 
individuals remain concealed under leaves in water in their cages. 
the evening of August 6 this species was heard singing in a pool 
in an abandoned stone quarry near the Meramec River. 
Hyla crucifera Wirp—While not commonly found, the spring 
peeper occurs in large numbers in some localities during the breed- 
ing season in February and Marc ey have been taken at 
Danby, Imperial, Sulphur Springs, Goldman, and Barnhart. These 
ardent little singers are little daunted by the presence of human 
time in captivity. During the night of March 21-22 many eggs 
were deposited in the water, where they were observed clinging 
singly to the under surfaces of submerged oak leaves or lying on 
the bottom of the container. Tadpoles introduced into a container 
with some Ambystoma larvae on August 8 were later found with 
only parts of the tails protruding from the salamanders’ mouths. 
In nature carnivorous salamanders are probably a serious menace 
to the tadpoles. One tadpole that was rescued from a salamander 
had a body length of 16.5 mm.; tail, 27.8; posterior legs, 20; great- 
est body depth, 7.1; greatest width, at anterior leg bulges, 8.5; 
tail depth, 8.2; thickness, 2.9. Some other features were: Dorsum 
olive drab; rostrum, flesh pink diffused with olive; digits, dark 
olive; latero-ventral areas, pearly iridescent, sen is arent, re- 
anterior fat dilation orange yellow, darkening to deep a 
Goldman, on moist fallen leaves beneath a sandstone ledge where 
its protective coloration was remarkable and this gave rise to the 
assumption that this might account for the infrequence of the dis- 
covery of specimens during the summer and fall months. 
versicolor versicolor (Le Contre)—Although Hurter 
asi * listed the tree toad from Jefferson County, we have not, 
as yet, been fortunate enough to take it here. It is ae 
rare about water in the spring, becoming arboreal in the summer
