Besides the pens of this calamaiy the ink-bag, the muscular mantle, and 

 the bases of the anns, are preserved in the Oxford clay. Some of the ink- 

 bags foimd 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 un- 

 derstand how these were preserved, as the recent calamaries " spill their ink"
