Cellariaeforma extentamuralis, new species; C. coronata, new species; and 

 Mawsonia e.xtensalala, new species 



(Figures drawn with aid of camera lucida) 



Figure A: Cellariaeforma extentamuralis, new species. Low power view of branch ll 

 having zooecia with ovicells and a\-icularia. Scale a. 



Figure B: Cellariaeforma extentamuralis. Several ovicelled zooecia surrounding an 

 avicularium. Scale b. 



Figure C: Cellariaeforma coronata, new species. Four zooecia. Upper and lower zooecia 

 show complete horseshoe-shaped cryptocyst ridge on calcareous frontal surface. Two 

 lateral zooecia covered by parchmentlike membrane having parentheses-shaped lines about 

 the orifice. Membrane is shown peeling off in places; the calcareous cryptocyst is beneaili 

 it. Scale r. 



Figure D: Mawsonia extensalata, new species. A branch showing prominent flaps or 

 cryptocyst extensions that give it a rough file-like appearance, and three large triangular- 

 beaked avicularia. Scale a. 



Figure E: Mawsonia extensalata. Several fertile zooecia and an avicularium. Ovicells 

 are widely open considerable distance above zooecial aperture. Cryptocyst flaps meet 

 directly over ovicells. Scale b. 



Figure F: Mawsonia extensalata. An avicularium. Triangular beak has a slighib 

 curved tip. Scale d.
