closely adjacent to spring streams and seepage water where it is 
most mary found. It also has been taken in wet leaves in the 
spring at Goldman, Barnhart, ier and Pevely. Its habits are 
much like those of the following specie: 
Eurycea lucifuga RarinesqueE—tThe spotted tail or hoosier 
salamander is not common. Specimens have been taken at Gold- 
man, Pevely, Barnhart, and Festus. It is usually found in or closely 
associated with caves and springs. During the rainy periods in 
the spring it may occasionally occur beneath limestone slabs on 
glades and wooded hillsides but it is usually present in the vicinity 
of the springs to which it repairs when surrounding areas become 
too dry. ce, in late spring, a specimen was observed in the 
open, clinging to a ledge above a crevice from which a spring 
. As it was approached it leaped down and scurried into the 
aperture. It is likely that a cave occurs under the hill but no speci- 
mens other than a larva taken August 7, 1932, with the gills in 
an atrophied state (and with a total length of 46 mm., and tai 
length 21mm.) were to be found at this place, near Barnhart, dur- 
ing the summer. At this time, it is believed, they enter caves; at 
least they occur in cave retreats more frequently than any of the 
eae species that inhabit this region. Two adults taken from this 
e habitat on March 26, 1932, have the following measurements: 
sata length, 151 and 105 mm., and tail, 78 and 61, respectively. 
Siren lacertina Linné—Specimens are occasionally taken in the 
Meramec and Big Rivers. 
Bufo americanus HoLsrook—The American toad is commo 
in Jefferson County where it has been taken at the follows local 
ities: Danby, oo Kimmswick, Sulphur Springs, Isle Du Bois 
Creek, Barn and Hollywood Beach. It requires warmer eve- 
nings than do fhe frogs to arouse it from hibernation to enchant 
the spring nights with its high-pitched, shrill calls. On the evening 
of June 19, 1932, a transformation from the larval state was ob- 
served, near Pacific, when thousands of tiny toads became active in 
the vicinity of river ‘sloughs where their small moving bodies seemed 
to imbue the gravel with life. By July 9 comparatively few of 
ese young amphibians were seen here and comparisons of collec- 
was also taken at this time. On the e evening of August 6 a baffling 
call was heard from the vicinity of several large pools; it was a 
high-pitched, rasping sound with little carrying power and of short 
duration, and although it had most of the qualities of the call of 
the toad, it was not readily associated with the species. Investiga- 
tion of the vicinity revealed the singers to be young specimens about 
an inch in len
