ITemi]>eues of represent.-itive types. 



The ligures on Plates 12 to 151, excei)ting fig. 9, Plate 22, represent the hemi- 

 peuis of a side split open so as to show the structures that are exhibited by the 

 entire circumference. Each figure is therefore twict; as wide as the organ iu its 

 normal condition. Where the organ is bifurcate one branch ouIn is s])lit, the other 

 being represented as invaginated. and with a i)oition of tlie reiractur uiuselc con- 

 tinuous with its apex.
