SCHIRMHOHLE. 



SrJiwimmhuhle. 



An open cavity under the concave umbrella, vaulted over by the subumbrella, and 

 opening freely below (or only partially closed at the margin by the circular velum). 

 The oral organs always lie in the central axial space of the umbrella cavity. All the 

 walls of the umbrella cavity are covered by the ectodermal epithelium of the subum- 

 brella.
