Belemnites canaliculatus, Schloth. (Zieten, t. xxi. f. 3.) ? The fragments 

 we have of this Belemnite agree well with Zieten's figure of B. canalicu' 

 latus^ which is very probably not distinct from B. sulcatus of Miller 

 (Geol. Trans., 2nd Series, vol. ii. part 2, p. 59, PI. VIII f 3). 



Loc. near Charee. 



Belemnites ? A nearly cj'lindrical fragment without a sulcus. 



Very like /?. clongatus of Miller. 

 Loc. n<!ar Charee. 



Nautilus hexagonus (M. C. t. 529) ? Flatted spheroidal, with a very 

 small umbilicus ; front approaching to flat ; sides rather conical ; septa 

 15 in a whorl ; aperture wider than long ; sipbuncle unknown. Diameter 

 31 inches, thickness 2\ inches, length of the aperture 1^ inch. 



This differs from N. hexagonus in having a smaller umbilicus and in 

 being more rounded. It wants the line that occurs in the middle of the 

 front of N. lineatus, which it nearly resembles. 



Loc. near Charee 



Ammonites Herveyi, (M. C. t. 195, Zieten, 19. t. xiv. p. 3.) var. 



This differs from the English specimens only in having a wider umbili- 

 cus. It agrees well with Zieten's figure, which differs a little from the 

 English specimens, to which A. macrccephaliis, figured by the same 

 author at Tab. b. f 1 and 4., approaches nearer. 

 Loc. near Charee. 



Ammniiites elephantinus. Approaching to globose, with a very wide 

 umbilicus exposing the inner whorls; whorls obtusely angular at their 

 sides, crossed by very prominent rounded costae, which divide into two 

 as they pass over the front ; aperture transversely elongated, gently 

 arched. Diameter 4 inches, thickness 2i inches, length of aperture above 

 an inch. 



Loc. near Charee. 



Ammonites formosus. Discoid, with a rounded edge, mnbilicate, radi- 

 ated ; umbilicus narrow, acutely conical ; radii numerous, slightly elevat- 

 ed, obscure near the umbilicus, often forked near their commencement, 

 passi g in a direct course over the front ; aperture sagittate, with trun- 

 cated angles. Diameter 5 inches, thickness 2| inches, length of aperture 

 \k inch. 



Loc. near Charee. 



Ammonites lamellnsvs. Discoid, thick, with a rounded margin, umbili- 

 cate, radiated ; umbilicus narrow, exposing a small portion of each inner 

 whorl, smooth ; radii numerous, elevated into obtuse lamellae, commen- 

 cing with a curve upon the edge of the umbilicus, often forked upon the
