Amblystoma jeffersonianum platineum Cope. Plumbeous, paler 
below. Width of head less than three times in length to groin. Eye larger. 
Body-length longer. Costal grooves 12. 
The sub-species Alatineum resembles somewhat individuals of 
Plethodon glutinosus, but it may be told from that species by its 
slenderer shape and the absence of parasphenoid teeth. 
Little seems to be known of the habits of the sub-species. 
DeKay gives them as frequenting springy places. (Paulmier, 
’02, p. 399.) In the State they are not common. 
Specimens, in the U. S. Nat. Mus., recorded by Cope from Cleveland. 
In Oberlin College, collected by Lynds Jones in Lorain County. 
7 Amblystoma microstomum Cope. Costal grooves 14. Color black- 
ish, with a plumbeous tinge, spotted indistinctly sometimes with lighter. 
Head broad, but small, and fusing with the body without a neck being evi- 
dent in proportion to body. Lower jaw prominent. Tail not as long as 
head and body, round, compressed posteriorly. Legs small. Altogether 
the slenderest species. Length 8 inches. 
Occurs in the State in general, but more common in hilly 
regions. They leave the water after breeding and are to be 
found under logs and partly buried in damp turf. The small 
eggs are attached to water weeds in little masses. By June they 
are ready to leave the water. At times this species leaves its 
winter quarters while it is yet winter, being taken in February.

in O. S. U. Mus., collected by E. V. Wilcox at Lancaster, and E. EK. Master-

family: PLETHODONTIDAE. 
Hemidactylum scutatum Tschudi. Above brown, lighter below 
where there is a sifting of dark blotches. Sometimes plumbeous dorsally, 
snout light. A marbling in the median dorsal region. Costal grooves 13. 
Length 3 inches. Toes 4-4. 
This species may be distinguished from those of the genus 
Plethodon by its having only four toes in the hind feet. 
It is a rare species for Ohio, but one specimen being thus far 
recorded. However, Hay (’92) mentions forty being taken at 
Brookville, Ind., which is within 10 miles of the Ohio-Ind. line. 
Specimens in the U. S. N. Mus., recorded by Cope from Ripley, Ohio; 
collected by Hoy. 
7. I follow Stejneger in discarding the genus Chondrotus Cope.
