The following is probably a posterior tooth of Odontaspis :— 
Oxgtes obligua , C. G. Giebel, Pauna d. Yorwelt, Pische (1847), 
p. 364.—Upper Eocene; Siildorf, Magdeburg. 
Genus ALOPECIAS, Muller & Henle. 
[Syst. Besphfeib. Plagiostom. 1841, p. 74.] 
Second dorsal fin and the anal very small. Caudal fin extremely 
elongated, with a pit at its root; no keel on the side of the tail. 
Teeth equal in both jaws, of moderate size, compressed, triangular 
and not serrated. 
The teeth of this genus are not readily distinguishable from those 
of Oxgrhina ; the following species, however, are recognized, though 
the first two are very doubtful: —
