CEPHALOPODA. RSS 
Pen broad, pointed behind; shaft broad, truncated in front ; 
lateral wings shorter than the shaft. 
Fossil, 9 species. Upper Lias, Wurtemberg; Calvados; 
Lyme Regis. Several undescribed species in the Oxford clay, 
Chippenham. 
Besides the pens of this calamary, the ink-bag, the muscular 
mantle, and the bases of the arms, are preserved in the Oxford 
clay. Some of the ink-bags found in the Lias are nearly a foot 
in length, and are invested with a brilliant nacreous layer; the 
ink forms excellent sepia. It is difficult to understand how 
these were preserved, as the recent calamaries “‘ spill their ink” 
on the slightest alarm. (Buckland.) This genus may probably 
turn out to belong to the Belemnitide.
