Figs. 1-9 illustrate the structure of the Nasal Passages. 



Fig. 1. Outline of the head, to show the position of the blowhole (reduced). 

 This is not absolutely correct, as the flesh of the head had been partially 

 removed. 



2. Enlarged view of the blowhole (nat. size), a, b, the anterior lip ; 



c, the interruption in the lip, where the lip becomes continuous with 

 the skin of the head ; d, posterior lip. mm, the median line of head. 

 x points to region that, in the next figure, has been cut across. 



3. The spiracular vestibule, exposed by cutting across the anterior lip at 



i'. and turning backwards the hinder lip d (nat. size), b, the right-hand
