SUMMARY 
In 1911 Hurter listed 102 eee: of camber vie Ae sora for 
the state of Missouri, several of which are not no wee as 
valid and many of which have undergone a more or cia mplete 
nomenclatorial metamorphosis. Since the publication of ‘that list 
the usual need for revision has arisen. Several new species have 
come to light, thus rant aig the need for a newer and more ac- 
curate compilation of specie 
The present paper lists 62 species known definitely to inhabit 
Jefferson County, Missouri, at this time. In addition to these the 
writers would like to include the following species which, while not 
generally classed as native here, are so related to surrounding Ale 
e their appearance in this county possible and a 
least worthy of recognition here: 
trophryne carolinensis ee — The narrow- 
mouthed toad has been taken in St. Louis County, and since the 
Meramec River offers ample opportunity for breeding, the species 
may also be native to Jefferson County. 
Natrix sipedon oa baheacaees ett R)—This water snake 
is fairly common just across the Mississippi River in Illinois and 
it is entirely possible that it may also ibe found occasionally on the 
Missouri 
Sternotherus odoratus (LATREILLE)—Since the musk turtle 
is found just across the Mississippi River in Illinois and just south 
of this county in St. Francois County, it may also occur here 
Graptemys geographica (Le Sueur)—The map turtle has been 
reported from the Meramec and Big Rivers by competent observers.
