Animal provided with arms and tentacles of nearly equal 



length, furnished with a double 

 alternating series of horny hooks, 

 from 20 to 40 pairs on each arm ; 

 mantle free all round; fins large, 

 medio-dorsal (much larger than in 

 Eig. 40). 



Fossil in the Oxford clay of 

 ChiiDpenham. Similar horny claws 

 have been found in the lias of 

 Watchett, and a guard equally thin 

 is figured in Buckland's Bridge - 

 water Treatise, t. 44, Fig. 14. 



In the fossil calamary of Chip- 

 penham the shell is preserved along 

 with the muscular mantle, fins, 

 ink-bag, funnel, eyes, and tentacles 

 with their horny hooks. All tho 

 specimens were discovered, and de- 

 veloped with unexampled skill, by 

 William Buy, of Sutton, near Chip- 

 penham.

* Fig. 40. Belemnotentkis antiqmts, \, ventral side, from a specimen in the cabinet 

 of "William Cunnington, Esq., of Devizes. The last chamber of the phragmocone is 

 preserved in this specimen, a, represents the dorsal side of an uncompressed phrag- 

 mocone from the Kelloway rock, in the cabinet of J. G. Lowe, Esq. ; c, is an ideal 

 section of the same. Since this woodcut was executed a more complete specimen has 

 been obtained for the British Museum ; the tentacles are not longer than the ordinary 

 arms, owing, perhaps, to their partial retraction ; this specimen is figured in Dr. 

 Mantell's " Petrifactions and their Teachings." d, is a single hook, natural size. The 

 specimens belonging to Mr. Cunnington and the late Mr. C. Pearce show the large 

 eicetabular bases of the Iiooks.
