Other teeth of Seyllium, from the Miocene of Herault, are noticed 
by P. Gervais, Zool. et Pal. Gen. (1867-69), p. 237, pi. xlvii. fig. 8. 
A vertebra from the Molasse of Baltringen iS also assigned to 
Seyllium by C. Hasse, Xatiirl. Syst. Ela-smobr., Besond. Tbeil (1882), 
p. 248, pi. xxxiii. fig. 10 ; while the same author describes vertebne 
of the type of Seyllium catuhis from the Oligocene of Palmnickeu 
(Paheontogr. vol. xxxi. 1884, p. 7, pi. ii. fig. and of Seyllium 
edwardgi from the Upper Chalk of Dorking {ibid. p. 7, pi. ii. figs. 
10, 11). See also F. Noetling, loc.cit. p. 96, pi. %"iii. fig. 10. 
Of very doubtful position are the small teeth from the Pliinerkalk 
of Bohemia and Saxon)', described under the following names : 
Seyllium crassiconum, A. E. Keuss, Yerstein. bohm. Kreideform. pt. i. 
1845, p. 4, pi. ii. figs. 21, 22, pi. xii. fig. 11 (Jlybodus appemlicu- 
latus, A. E. Keuss, Geogn. Skizze Bdbmen, vol. ii. 1844, p. 219.

dug humholdti, A. Fritsch, op. eit. p. 11, fig. 21). 
The preoccupied term Paheoscyllium has been employed by W. von 
der Marck for a fossil dog-fish from the Senonian of Arenfeld, 
\V estphalia, the generic distinctness of which from Seyllium yet 
remains to be demonstrated. The species is named P. dechenP. 
It is also not improbable that the teeth described under the fol- 
lowing names belong to Seyllium or an allied genus : —
