SYMPATHETIC NERVES OF THE TERRESTRIAL CARNIVOEA.

superficial cardiac plexus. It is connected to the anterior pul- 

 monary plexus on one or both sides, and to a plexus around the 

 main branches of the aortic arch. In some species branches of 

 the vagus and sympathetic reach the cardiac plexus through the 

 latter. The composition of the plexus in the species described in 

 this paper are : — 



Felis hengalensis (text-fig. 4) : — Two branches from the left 

 vagus (/), a twig from the left anterior pulmonary plexus 

 (A. P.P.), and a thick branch from the inferior cervical ganglion 

 of the left sympathetic (C.B.S.). These form a superficial plexus 

 without ganglia. The deep plexus receives a branch from the 

 right vagus (/'), a branch from the right anterior pulmonary

plexus (A'.P'.P'.), and a branch from the left recurrent laryngeal 

 nerve ; but it gets no separate sympathetic filaments. 



Paradoxurus larvatus (text-fig. 6) : — Two oSshoots of the left 

 vagus unite to form a cardiac nerve (/) which runs to the plexus. 

 No branches of the left sympathetic run directly to the plexus, 

 but they enter the plexus round the branches of the aortic arch 

 (A.V.P.). The right vagus gives two branches (/') and the left 

 recurrent laryngeal nerve contributes ; but no branches come 

 from the right sympathetic. The plexus communicates with the 

 pulmonary plexus.
