The umbrella is bell-shaped, nearly cubical, flattened above, 

 and slightly higher than broad. The gelatinous substance of the 

 umbrella is nearly uniformly thick. The exumbrella is granulated, 

 divided into several areas by grooves as in some other species of 

 this genus, such as C7i. murrayana Hseckel.* The aboral circular 

 groove is deep and separates the apical area from the hanging 

 coronal area. The four interradial grooves are deep and run 

 down from the circular groove along the interradial corner of 

 umbrella nearly to the origin of pedalia. The eight adradial 

 grooves run down also from the circular groove, becoming gradu- 

 ally wide and indistinct in the lower half of umbrella. 



The stomach cavity is flat and somewhat octagonal. The 

 interradial sides of the octagon are shorter than the perradial. 

 The cavity is a little broader than the umbrella-radius. The 

 manubrium is short with four large lips. The four interradial 

 groups of gastric filaments or the phacelli are well developed, 

 occupying the interradial sides of the octagonal stomach cavity. 

 Each phacellus consists of from eight to twelve brush-like filaments. 



The distance of the sensory niche from the umbrella-margin 

 is very short, it being only about i/e the distance between pedalia.
