An indeterminable detached tootb, not of Lepidotus , from the 
Cenomanian (Planerkalk) of Plauen, Saxony, is named Lepidotus 
plauensisl by C. E. Fischer, Allg. deutsch. Haturh. Zeit. n. s. 
vol. ii. (1856), p. 137, fig. 1. 
The undefined name Lepidotus cottce is given by Agassiz (Poiss. 
Foss. vol. ii. pt. i. 1844, p. 306) to unknown fossils from the u Chalk ” 
of Hobenstein, near Schandau, Saxony. A plaster cast of a portion 
of Spbaerodont dentition in the Enniskillen Collection (P. 7422) 
is thus named, without reference to locality. 
- Gyrolepiclotus schmidti (J. Y. Bohon, Mem. Acad. Imp. Sci. St. 
Petersbourg, [7] vol. xxxvi. no. 13, 1889, p. 8, pi. i. figs. 4, 10, 
13, 14) from supposed Permian in the province of Jenissei, Siberia, 
is described as related to Lepidotus; but the type specimen in the 
Academy of Sciences, St. Petersburg, seems to the present writer to 
be most probably an imperfect example of a Palaeoniscid. The 
same remark applies to Lepidopterus crassus (H. Pohlig, Festschr. 
70ten Geburtst. B. Leuckarts, 1892, p. 63, pi. vii. fig. 3) from the 
Lower Permian of Thuringia, described as a link between Arnbly- 
pterus and the Semionotidse. , 
1 The Tertiary teeth noticed by Agassiz also under this name pertain to 
teleostean fishes.
