REPORT ON THE PENNATULIDA. 151 



It is clear therefore, that as in Funiculina, there is only one bisecting 

 plane that will divide the polype into two perfectly symmetrical halves, 

 and it is also evident from Figs. 3 and o, and from the description given 

 above that the j)lane of .ti/mmetrij is perpendicular to the flat surface of 

 the leaf, and is therefore the plane of section adopted in Fig. 4. 



The retractor muscles pull back the bases of the tentacles at the 

 same time shortening the stomach, as described above, so as to make 

 room for them ; the completion of the retraction of the tentacles is 

 effected by their own intrinsic system of longitudinal muscles ; 

 and the final action of the great retractor muscles is by pulling on the 

 bases of the calyx processes to bring these towards one another and so 

 completely close the mouth of the polype cup.
