regions. Wilcox (g1) mentions one showing little or no dorsal 
groove. ‘They are almost the last of the salamanders to go into 
winter quarters and appear early in the spring when, soon after 
emerging, they begin to breed. 
This species is not common in the State. 
Specimens in the U. S. Nat. Mus., recorded by Cope from Lancaster and 
Ripley. In Cin. Soc. Nat. His., collected by Rev. Mark, in Hamilton Co.; 
in O. S. U. Mus., from Portsmouth and Sugar Grove. 
Amblystoma punctatum Linn. Larger than preceding. Body dark 
brown or black, with a series of large circular yellow spots over the body, 
head and tail; on the tail the spots are sometimes confluent. Below anda 
short distance up on the sides are smaller spots that give a pepper-and-salt 
appearance. Legs also spotted above as the dorsal part of the body. Costal 
grooves sometimes Io, generally 11. Length 6% inches. 
This species resembles somewhat in size and general features 
the species Hgvinum, but in tégvinum the spots are not circular as 
in punctatum, but are elongated and often fuse into one another. 
Moreover, figvizum has twelve costal furrows. Its habits are 
similar to those of figvinwm, both being more terrestrial than 
many of the other salamanders, being found under rotten wood 
away from water, in cellars, etc, The eggs are laid in masses in 
ponds and ditches. 
In the State they are found in small numbers, but they are 
generally distributed. Eastward they replace figrinum. 
Specimens in the U.S. Nat. Mus., recorded by Cope from Cleveland. 
In Oberlin College, collected by Lynds Jones in Lorain Co.; in O.S. U. 
Mus., collected by J. C. Bridwell and E. V. Wilcox at Columbus; also 
reported from Sugar Grove. 
Amblystoma tigrinum Green. Above, body yellowish brown to black, 
with irregular blotches and spots of yellow, sometimes almost forming trans- 
verse bands. Below, lighter with few spots. Form large, sometimes the 
spots are inconspicuous. Costal grooves 12. Tail long, compressed. Larg- 
est and heaviest of the salamanders, save the first two, Vecturus and Crypto- 
branchus. Vength ro inches or under. 
The larva of this species is the axolotl of the West, where, 
over the plains, the pools abound in the spring with the young. 
Later as summer sets in they undergo metamorphosis and begin 
a terrestrial existence. The gills are lost and the length increases 
nearly one-half. Breeding takes place about the first of April. 
‘The eggs are laid in pools and are attached to water-plants. The
