186 LABYEINTHODONTIA. 



from the Lower Permian of Telots, near Autun. It is 

 figured of the natural size by Gaudry in the ' Nouv. 

 Archiv. d. Museum,' vol. x. pi. i., and on a reduced scale 

 . in the ' Mem. Soc. Hist. Nat. d'Autun,' vol. i. pi. ii. (1888), 

 as Actinodon frossardi. The extremity of the muzzle is 

 abnormally expanded by pressure. The orbits appear to 

 be smaller than in the preceding specimen, but the pre- 

 orbital ridges and median depression are very distinct. 

 The contour of the skull seems to be more like that of the 

 type of A. brevis, Gaudry.

Genus COCHLEOSAURUS, Fritsch 1 . 



Skull (imperfectly known) of the same general contour as in the 

 preceding genus, but with a posterior projection from each supra- 

 occipital, the squamosal of either side divided into an anterior and 

 a posterior moiety, and no epiotic cornua. It is considered that 

 the jugal entered into the formation of the outer border of the 

 orbit. 



Cochleosaurus bohemicus, Fritsch 2 . 

 Syn. Melosaurus bohemicus, Fritsch 3 . 



The type species. Length of skull about 0,165 (6*6 inches). 

 Hob. Europe (Bohemia). 



47493. Cast of a slab showing the dorsal aspect of the imperfect 

 skull. The original, which is the type, was obtained from 

 the Gaskohle (Lowest Permian) of Nyfan (Pilsen), and 

 is figured by Fritsch in his ' Fauna der Gaskohle,' vol. ii. 

 pi. lx. fig. 1, and diagrammatically on p. 30, fig. 137. 



Presented by Dr. Anton Fritsch, 1876. 



** Genus GAUDRYA, Fritsch 4 . 



Founded upon the anterior extremity of a palate, in which there 

 are two vomers, a single row of marginal teeth, and numerous 

 small teeth on the palatines. It does not appear how this form 

 can be distinguished from the preceding or following genera.
