NAUTILUS Woodwardii. 
TAB. DLXXI.—fg. 3. 
Spec. Cuar. Discoid, granulated ; inner whorls 
exposed ; sides of the whorls angular ; front 
rounded with a linear sulcus along its middle: 
aperture obovate with angular sides. 
Syn. Conch. Naut. Ammonites Woodwardii, Martin 
Pet. Derb. t. 35. f. 4. & 5. 
Tur granulations upon this fossil are arranged in con- 
centric lines; they cover the whole surface: the sub- 
stance of the shell is very thin where the furrow occurs 
upon the front, for that on the outer whorls is met by a 
sharp carina in the cast, which is otherwise smooth. 
Although from its similarity in form to the preceding 
species this is placed asa Nautilus, it is highly probable 
that it belongs to the genus Bellerophon; for although 
I have removed a considerable portion of the shell, no 
traces of septa can be discovered: the furrow on the 
front is also in favour of this opinion. 
Drawn from Mr. Martin’s specimen, which was found 
at Winster, Derbyshire.
