Other teeth of Scyllium, 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 
Scyllium by C. Hasse, Katiirl. Syst. Elasmobr., Besond. Theil (1882), 
p. 248, pi. xxxiii. fig. 10 ; while the same author describes vertebrae 
of the type of Scyllium catulus from the Oligocene of Palmnicken 
(Palaeontogr. vol. xxxi. 1884, p. 7, pi. ii. fig. 12), and of Scyllium 
eclwardsi from the Upper Chalk of Dorking (ibicl. p. 7, pi. ii. figs. 
10, 11). See also E. Noetling, loc. cit. p. 96, pi. viii. fig. 10. 
Of very doubtful position are the small teeth from the Pliinerkalk 
of Bohemia and Saxony, described under the following names :— 
Scyllium crassiconum, A. E. Beuss, Yerstein. bbhm. Kreideform. pt. i. 
1845, p. 4, pi. ii. figs. 21, 22, pi. xii. fig. 11 ( Uyboclus appendicu- 
latus, A. E. Beuss, Geogn. Skizze Bcihmen, vol. ii. 1844, p. 219.— 
Scyllioclus crassiconus, H. B. Geinitz, Palaeontogr. vol. xx. pt. i. 
p. 295, pi. lxv. fig. 8, and A. Eritsch, Bept. u. Eische bohm. Kreide¬ 
form. p. 11. fig. 22.— Hyhodus serratus, C. E. Eischer, Allg. deutsch. 
Katurh. Zeit. n. s. vol. ii. 1856, p. 140, pi. ii. fig. 36); Scyllium 
humboldti. A. E. Beuss, op. cit. pt. i. p. 4, pi. iv. figs. 4-8 (Scyllio- 
dus humboldti, A. Eritsch, op. cit. p. 11, fig. 21). 
The preoccupied term Pcilceoscyllium has been employed by W. von 
der Marck for a fossil dog-fish from the Senonian of Arenfeld, 
Westphalia, the generic distinctness of which from Scyllium yet 
remains to be demonstrated. The species is named P. clecheni 1 . 
It is also not improbable that the teeth described under the fol¬ 
lowing names belong to Scyllium or an allied genus :—■
