Catenicellid Cheilostome Bryozoa II.* Introduction to Ovicell Complexes

RE Wass and C Banta

Abstract

Catenicellid ovicell complexes are of two types, 'terminal' and 'subterminal'. The former, found at the end of a branch, generally consists of a female zoid with ovicell, together with vestigial ovicell zoid and apical chamber. Subterminal ovicell complexes bud distally from part of the complex and are generally composed of female zoid with ovicell, lateral zoid, and ovicell zoid with apical chamber. For all 13 species described, the position of the ovicell complexes in the budding pattern is shown diagrammatically. Frontal walls and associated structures of some species not described in a previous study are included.
