Cellaria mo7iiliorata, new species 



(Figures drawn with aid of camera lucida) 



Figure A: Part of fertile branch siiowing every zooecium topped by endotoichal ovicell. 

 Ovicells give branch a swollen look. Frontal walls of neighboring distal zooecia meet in 

 salient suture over each ovicell. Zooecia are in series of four around the branch. Scale a. 



Figure B: Enlargement of part of the branch in figure A showing beaded cryptocyst 

 ridges (cr), orifices, ovicell openings, and three ovicells (ov). Mural rim (mr) smooth, 

 thin, and slightly raised. Scale b. 



Figure C: Part of nonfertile branch showing autozoids in series of four and in hexagonal 1 

 areolation. Two lower zooecia have opercula (op) in place in orifice. Scale a. 



Figure D: Part of nonfertile branch showing three autozooecia and one avicularium i 

 inserted between them. Scale b. 



Figure E: Avicularium with beaded frontal, raised beak narrowed and sllghth" curved. . 

 Scale b. 



Figure F: Avicularium of figure D enlarged. Scale d. 



Figure G: Branches, meeting at a node with its tangle of radicle fibers. Basal branch ij 

 narrows a bit in this specimen. Scale c. 



FiGtTRE H: Node with its tangle of chitinous radicle fibers. Tip of basal branch in this 

 colon}" widened a bit at joint. Scale e. 



Figure I : Branching, tangled, double radicles growing from front of an autozoid. Scale a. 



Figure J : Zoid with single radicle growing from its front. Volcano-shaped raised front 

 is calcareous; tube itself is chitinous. Scale b. 



Figure K: Mandible of an avicularium. Scale d. 



Figure L: Zooecial orifice showing beaded upper lip and smooth pouting lower lip. 

 Scale d.
