NAUTILUS Woodwardii. 
TAB. DLXXI.— fig. 3. 
Spec. Char. 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. 
The 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 as a Nautilus, it is highly probable 
that it belongs to the genus Rellerophon ; 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.
