Fig. 7. Transverse section through the orbital region of the head of 

 the Plaice represented in Fig. 1, PL V. The dorsal and ventral parts 



of the head have been cut away for convenience in making the series of 

 sections, and the lens of the right eye has been removed. The drawing is 

 slightly diagrammatic in that the minute structure of the tissues is not 

 represented. The proportions and positions of the various parts are 

 accurately represented.
