BRYOZOA OF THE PHILIPPINE REGION 205 



Ovicell hypcrstoniial: 



Vibraculum dorsal — 



Seta (or flagellum) short, without tooth Scrupocellaria. 



Long denticulated cilium; longitudinal fibrous bun- 

 dles on the dorsal Caberea. 



Ovicell surmounted by an avicularium; nonarticu- 



lated colony Canda. 



Fibrous radicular bundles on the margins of the 



colony Amastigia. 



Avicularium dorsal Notoplites. 



Dorsal without heterozooecia — 



No radicular dietella Jubella. 



Radical inserted below the chitinous joints — 



Avicularia present Tricellaria. 



No avicularia Bugulopsis. 



A single chitinous joint Monartron. 



Segments at the extremity of long radicular 



pedicells Rhabdozoum. 



Ovicell as in the Alderinidae; internal avicularia Flabellaris. 



Ovicell wanting Hoplitella. 



Ovicell endozooecial : 



Colony biserial Menipea. 



Segments formed of one or two zooecia on the same 



colony Maplestonia 



Group 1. OVICELL HYPERSTOMIAL 

 Genus SCRUPOCELLARIA Van Beneden, 1845 



The ovicell is smooth or perforated. There is a frontal avicu- 

 larium, a distal marginal avicularium and a proximal dorsal avicula- 

 rium. A radicular dietella is enclosed in the dorsal avicularium. 

 The seta of the vibraculum is short and without teeth (lateral branches 

 of Harmer). The articulation has two chitinous tubes but the outer 

 zooecium has the articular tube near the middle of the zooecium. 

 14-16 tentacles. A scutum often present. 



Genotype. — Scrupocellaria (Sertularia) scruposa Linnaeus, 1758. 



Range. — Eocene (Lutetian) — Recent.
