the State. Prof. H. Garman considers the size of gryllus (1.4 in.) 

 as given by Le Conte as the only reliable difference. This is much 

 larger than any in my series, and as the Samburg specimens are 

 smaller and more slender than those from the Cumberland plateau, 

 the theory that the southwestern frogs are larger than northeastern 

 ones is contradicted. Le Conte defines the habitat of gryllus in the 

 south Atlantic States, and that of crepitans in the remainder of the 

 eastern United States, but Prof. Cope's identification of the Smith- 

 sonian series allots specimens of both forms to both sides of the Alle- 

 gheny Mountains in such a way that faunal definitions lose their 

 significance. Such being the case I have lumped the entire Ten- 

 nessee series under the original specific name. 



Specimens: Samburg, 10 ad.; Chattanooga, 2 ad.; Sawyer's 

 Springs, 12 ad. ; Greeneville, 4 ad., 4 juv. 



Genus CHOROPHILUS Baird. 



37. Chorophilus triseriatus (Wiedni.). Chorus Frog. 



A male and female were taken together in a pool on the'Chicka- 

 mauga battle field, eight miles from Chattanooga. I heard the 

 voice of this species in other parts of the State but do not remember 

 it west of the central basin. 



The specimens have been mislaid. 



Genus HYLA Laurenti. 



38. Hyla cinerea semifasciata (Hallow.). Hallowell's Tree Frog. 



The name of the typical eastern form of this species has a rather 

 peculiar history. Later authors have adopted the name carolinensis 

 of Gunther, (Cat. Bat. Sal., B. M., 1858, p. 105). Giinther in his 

 synonymy quotes a "Calamita carolinensis, Penn., Zool. Arct. II, p. 

 331," and, contrary to good rules, our most noted writers in this 

 branch of science have used the name binomially as " Hyla carolin- 

 ensis Pennant." 



Reference to the Arctic Zoology shows us that Pennant not only 

 never imposed original binomials or polynomials on previously 

 unnamed species but that the "Calamita carolinensis" of Gunther is 

 mythical. The entire reference to it by Pennant is as follows: 



"Fr.[og] with the back gibbous, ciuereous, and smooth: belly 

 yellow and granulated; on each side from the nose to the rump is a 

 line; the same on the outside of the thighs and legs; toes bullated
