308 BIE. ATTHEY ON PALATAL TEETH OF A 



of the tootli ornamented with transverse ridges ; but a further 

 comparison cannot at present be made, as the figure given by 

 M'Coy was from a specimen broken at both ends. 



As it appears to be advisable to attach some name to this 

 interesting fossil, and seeing that it agrees in some essential 

 points with the genus Climaxodus, M'Coy, I propose to refer 

 it provisionally to that genus, and, further, to distinguish the 

 species which I have found at Newsham by the name of Cli- 

 maxo clus lingucBformis . 



Also I avail myself of the present occasion to announce that, 

 in addition to Climaxodus and the species already described in 

 former communications to the "Annals," several other interest- 

 ing forms have been obtained from the shale of the Low-Main 

 Seam, of which no notice has been given, the most important of 

 these being the follovidng : — 



C(ELACANTHUS LEPTURUS, Ag. 



Several entire specimens have occurred, but usually in a much 

 disturbed state. Separate scales are not uncommon. 



Stkepsodus saukoides, Hiixl. 



Tavo or three jaws of this species, with the teeth attached, 

 have been obtained, and numerous separate teeth. 



GrYKOLEPis Rankinii, Ag. 



Several specimens have occurred in a more or less complete 

 state of preservation. 



Platysomus parvultjs, Young {9). 

 A few entire specimens have occurred. 



AmphIcentritm, sp. indet. 



Three nearly perfect specimens have been found, and numer- 

 ous mandibles exhibiting tuberculated plates.
