Anatomy and Physiology. 
1 . General Morpholoyy. 
The flexure of the intestine is downwards, “pedal,” in the Cephalopods 
and Pteropods ; upwards, “cerebral,” in all other Mollusca^ except Nudi- 
branchs and Tectibranchs, which have scarcely any flexure at all. The 
heart lies on the cephalic side of the intestine in the Nudibranchs, 
Cephalopods, and Pteropods, but on the pedal side of it in the Heteropods 
(^Atlanta)^ Pulmonates, and Pectinibranchs. The arms of the Cephalopods 
are homologous to the ventral part of the original circular velum or 
architroch, the valve within the funnel to the foot of the Gastropods, 
the funnel itself to the epipodium. The six or eight trunks on which 
the tentacles of Nautilus are placed are homologous to the arms of the 
Dibranchiate Cephalopods, one of those processes being modified in the 
male to the spadix, as one arm of the latter is hectocotylised. The hood 
of Nautilus is homologous either to the two anterior arms, or more pro- 
bably to the neck-plates of the Dibranchiates. Only the mucro of the 
bone of Sepia is homologous to the shell of Nautilus. Blake, Ann. N. H.
