176 MANUAL OF THE MOLLUSCA. 
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; jins large, 
medio-dorsal (much larger than in 
Fig. 40). 
Fossii in the Oxford clay of 
Chippenham. 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 the 
specimens were discovered, and de- 
veloped with unexampled skill, by 
William Buy, of Sutton, near Chip- 
penham.

* Figo, 40. Belemnoteuthis antrquus, }, 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 hag 
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 
acetabular bases of the hooks.
