In Canis thotis (text-fig. 5) the superficial and deep plexuses 

 are very well mai'ked. The former (S.C.P.) receives a thick cord 

 from the left vagus (/), several twigs from the right vagus (/'), 

 communications from the left anterior pulmonary plexus, and 

 a thick sympathetic filament (C.B.S.). The latter (D.C.P.) 

 is formed by branches of the right vagus (/'), left recurrent

 filaments. 



In Cynictis penicillata (text-fig. 10 B) the cardiac plexus 

 receives a branch from each vagus (/./'), one from the left recur- 

 rent nerve (e), and communications from the anterior pulmonary 

 plexuses (A. P. P.)- ^o branches come separately from the right 

 sympathetic, but the left inferior cervical ganglion (I.C.G.j sends
