found within the boundaries of the State being known to breed 

 here. In the numerous caves and cave streams the members 

 of the genus Spelerpcs are abundant, and the other Plethodon- 

 tidae find suitable homes among the rocky hills and valleys. 

 The most) noted locality for batrachians is Salamander Pond, 

 a pool about fifty feet in diameter on the summit of a rather 

 high divide less than three miles from the University. In this 

 pond Ambystoma micro&omum , jfffersoniamtm, tigrinum, puncta- 

 tum, and opacum, Diemyctylus viridescens and several species of 

 toads and frogs breed. 



1. *Necturus maculatus Raf. 



WATER-DOG. 



Occasionally seen in the larger creeks. 



2. Ambystoma microstomum (Cope). 



SMALL-MOUTHED SALAMANDER. 



This species has been taken a few times about the mouth of Mayfield's 

 Cave and at Salamander Pond. 



3. Ambystoma jeffersonianum (Green). 



JEFFERSON'S SALAMANDER. 



A very abundant species. More than one hundred and fifty have been 

 taken at one haul of a net in Salamander Pond. They appear in the 

 pond in January. Eggs have been taken as early as the sixteenth of that 

 month and they are abundant as soon as the ice leaves. The young have 

 been observed transforming in the latter part of July. 



4. Ambystoma tigrinum (Green). 



TIGER SALAMANDER. 



Rather rare. A few have been taken from under logs in winter and a 

 very few have been observed at Salamander Pond during the breeding 

 season. 



5. Ambystoma punctatum (Linn.). 



SPOTTED SALAMANDER. 



Moderately common. Breeds in several small ponds near Bloomingtoii, 

 including Salamander Pond, and may be found immediately after spawn 

 ing, under logs and stones in the woods and fields. 



6. Ambystoma opacum (Gravenhorst). 



MARBLED SALAMANDER. 



Common. In September and October, this species, with eggs, occurs in 

 Salamander Pond. The nests are cavities in the ground, near the surface, 

 under chunks of wood or the dried crust of algae and other plants. They 

 contain from fifty to more than one hundred and fifty eggs. The larvae 

 may reach a length of an inch while in the egg, but they must have water
