divide into numerous branches which form a nerve plexus {Cp) 

 extending completely around the eye. 



The arrangement of the ciliary nerves in relation to the ciliary 

 ganglion of the sparrow, as I have found it, differs in some 

 respects from that in the hen as described by Carpenter ('11) 

 and Lenhossek ('11).

Carpenter finds one large branch and a variable number of 

 smaller branches leaving the distal side of the ciliary ganglion. 

 He also found that the branch from the ophthalmic nerve divides 

 into two. One of these unites with one of the nerves from the 

 ciliary ganghon; the other runs directly to the eye and forms the 

 long ciliary nerves. He describes the ganglion as situated 

 directly on the third nerve and not connected by a short branch 

 He claims that all th,e branches from the distal portion of the
