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.
