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 platineum 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. 

 (Garman, '91.) 



Specimens in the U. S. Nat. Mus., recorded by Cope from Columbus. 

 In the Mus. Cin. Soc. Nat. His., collected by Chas. Dury in Hamilton Co.; 

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

 man at New London. 



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.
