146 Mr. S. S. Buckraan on the 



Genus Epalxites, Mascke. 



" Type, A7n. contractus anceps, Qu." 

 5 species, of wliich 4 are new. 



Genus Metaxytes, Mascke. 



" Type, Met. intermedms, n. f ." 



18 species, of which all are new. 



Depressed, strong-ribbed Stephanoceratoids, with ears. 



Genus NORMANNITES, Mun.-Chulm. 



" Type, Am. braikenridgu, Sow." 



54 species, of which all but 2 are new. 



In placing Am. hraikenridgii, Sow., as tlie type of this 

 genus Mascke has disregarded Munier-Chalmas. That 

 author {' Compte-rend. Soc. Geol. France, 1892, xiv. p. clxxii) 

 specially mentioned Am. hraikenridgii, d'Orb. The differ- 

 ence is very important, for Dundry, which is the type- 

 locality of A. hraikenridgii, Sow., possesses no strata at all 

 which could yield Ain. hraikenridgii, d'Orb. Tlie Am. 

 hraikenridgii, Sow., is from the sauzei-zowQ, and its lappets, 

 being lateral, not latero-peripheral, indicate a species of the 

 saiizei group ; it belongs, therefore, to the genus Otoites, 

 Mascke. There is indirect evidence for this conclusion — the 

 specimens in the Bristol Museum labelled Am. hraikenridgii 

 were the species M'hich has of late years been termed 

 A. sauzei, d'Orb. It seems desirable that the confusion 

 between the Sowerbyan and d'Orbignyan species of Am. 

 hj-aikenridgii should be prevented ; and as for a long time the 

 need of a distinguishing appellation for the latter species has 

 been felt, the present opportunity may be taken to give the 

 name 



Normannites orhignyi, nov. 



1846. Ammonites hraikenridyii, d'Orb. (uon Sow.), Pal. franf., Terr, 

 jur., Ceph. pi. cxxxv. figs. 3, 4 only. 



Therefore Munier-Chalmas's genus will read thus : — 

 Genus NOEMANNITES, Mun.-Chalm. 



Type, A. hraikenridgii, d'Orb. (non ^o^\ .\ = Normannites 

 orhignyi. 



And in the genus Otoites there will be three named species 

 to deal with : — 0. sauzei (d'Orb.) ; 0. hraikenridgii (Sow.), 

 thinner, less spinous ; 0. contractus (Sow.).
