A tooth very suggestive of this genus, from the Tertiary of Java, 
is also described by K. Martin, Samml. geol. Ileichs-Mus. Leiden, 
[1] vol. iii. (1883), p. 25, pi. ii. fig. 10 ( Galeocerdo , sp. ?). Doubtful 
teeth, probably from the Swiss Molasse, are also recorded, without 
description, under the name of Hjfhyma dv.bia, L. Agassiz, tow., cit. 
p. 235. 
The so-called Sphyrna denticulata , Munster (Agassiz, torn., cit. 
p. 230, pi. xxvi.cn figs. 00, 01), is founded upon the anterior cone 
of a tooth of Notidanus jprimigenivs of Tertiary age. S'phyrna

upon a tooth of Squatina, as remarked by Probst (tom. cit. p. 152j./^- i ' < V / D.

Snout short; mouth crescent-shaped, with well-developed, long 
labial folds. Spiracles minute. Vo pit at the root of the caudal 
fin ; second dorsal fin scarcely smaller than the first. Teeth small,

Vertebrae from the Danian Beds of Ciply and the Crag of Ant¬ 
werp, Belgium, are referred to Mugtelus by C. Hasse, Vatiirl. Syst. 
Elasmobr., Besond. Theil (1882), p. 283, pi. xl. figs. 13-15. 
The following vertebrae are referable to members of the family 
Carchariidae, but the generic determination of these fossils is some¬
