Brj'ozoa. 457 



The projecting avicularium, which sometimes takes up the whole 

 breadth of the distal zooecium and as a rule conceals the median 

 tooth, is provided with a broadly rounded mandible which is a little 

 broader than long. The mandibular area is not twice as high as 

 the membranous one. 



The ooecia, most of which take up the whole breadth of the 

 distal zooecium, are tuberculous, and as a rule half as broad again 

 as high. In most of them there is found a fairly large pore a 

 little distally to the free margin, but it is often more or less covered 

 by the above ooecial arch.
