Studies made on several species, including Venus meroenaria, demonstrated 

 the presence of cardio-inhibitory nerves, and apparently these nerves only. 

 Stimulation of visceral ganglion failed to obtain cardio-accelerator effects. 

 Auricles and ventricle are supplied with inhibitory nerves from visceral 

 ganglion and the cardio-inhibitory mechanism can be excited reflexly by 

 stimulation of siphonal nerves. - J.L.M.

It is concluded that, with the exception of Mytilus , for which results 

 were inconclusive, auricles and ventricle of lamellibranchs are supplied 

 with inhibitory nerves from visceral ganglion or ganglia. These nerves 

 enter the heart at the base of the auricles. - J.L.M.
