Fam. PROTEIDÆ.
_Necturus maculatus_ Rafin. University Lake, Olentangy River, and Lake
Erie. Near Sandusky, on both the Lake and Bay shore, decaying specimens
of the mud-puppy, mostly young, were found in numbers in 1900. Almost
all were covered with a fungus—probably _Saprolegnia_.
Fam. CRYPTOBRANCHIDÆ.
_Cryptobranchus alleganiensis_ (Daudin.) Columbus.
Fam. AMBLYSTOMATIDÆ.
_Amblystoma opacum_ (Gravenh). Portsmouth and Sugar Grove.
_Amblystoma tigrinum_ (Green). Columbus. This salamander appears early
in the Spring and is often found in small pools. Individuals are taken
nearly every Autumn in the basement of the Biological Hall while they
are seeking shelter. A specimen taken thus had many characteristics in
common with _xiphias_ Cope and it is doubtful how valid _xiphias_ is, as
a species.
_Amblystoma microstomum_ (Cope). Columbus and New London.
Fam. PLETHODONTIDÆ.
_Plethodon cinereus cinereus_ (Green). Sugar Grove.
_Plethodon cinereus erythronotus_ (Green). Sugar Grove, Columbus, and
Worthington. In the early part of the year this is the commonest
salamander in the ravines in Franklin County. It is found generally away
from water, under loose debris two or more rods from the stream.
_Plethodon glutinosus_ (Green). Sugar Grove. This salamander is found in
such localities as were mentioned for _P. c. erythronotus_.
_Gyrinophilus porphyriticus_ (Green). Sugar Grove.
_Spelerpes bilineatus_ (Green). Sugar Grove. Habits apparently aquatic.
_Spelerpes longicauda_ (Green). Sugar Grove. This salamander is abundant
in this region where it may be found in May under stones at the edge of
the water together with its eggs; the eggs are attached to the under
side of a hollow stone. Some individuals were found in May, 1900, away
from water.
_Spelerpes ruber_ (Daudin). Fairfield County.
_Desmognathus fusca_ (Rafin). Sugar Grove and Perry Co. Aquatic in
habits.
Fam. PLEURODELIDÆ.
_Diemictylus viridescens miniatus_ (Rafin). Sugar Grove.
Fam. BUFONIDÆ.
_Bufo lentiginosus_ (Shaw). Columbus and Knox County. This is the common
toad of Central Ohio.
_Bufo lentiginosus americanus_ LeConte. A specimen from the sand dunes
of Cedar Point, Sandusky, Ohio.
Fam. HYLIDÆ.
_Acris gryllus crepitans_ Baird. Knox County, Central College and
Columbus. The common cricket-frog of Central Ohio is this subspecies.
The young resemble the species _gryllus_ LeConte in having the under
surface of the thigh reticulated and blotched.
_Chorophilus triseriatus_ (Wied.). Sugar Grove.
_Hyla versicolor_ LeConte. Knox County and Columbus.
_Hyla pickeringii_ Storer. Sugar Grove.
Fam. RANIDÆ.
_Rana virescens_ Kalm. Sugar Grove and Columbus.
_Rana palustris_ LeConte. Sugar Grove.
_Rana sylvatica_ LeConte. Knox County and Sugar Grove.
_Rana clamata_ Daudin. Columbus.
_Rana catesbiana_ Shaw. Columbus.
