 Canu.

The zoarium is long, tubular, hollow. The superior base is per- 

 forated by a median aperture surrounded by a thick peristome. 

 Certain cells are transformed sporadically into large unguiculated 

 oblique avicularia witli pivot. The aperture is suborbicular, without 

 cardellcs. The ovicell is small, hyperstomial.
