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.
