and mastoid, while the malar is, in the idiot skull, divided by a 
vertical suture into a premalar and postmalar (post frontals, ante-

 Worms.—M. G: Pruvot has, at Banyuls-sur-Mer, investigated 
the nervous system of the Eunicide, and finds: (1) That the cere-

Supplied with nerves entirely from the cerebral center, and that 
odd posterior antenna represents a pair of appendages that

connections; (4) That the stomato-gastric system has essentially 
the same disposition as the general nervous system ;
