BRYOZOA OF THE PHILIPPINE REGION 



225 



sponding lateral wall; the entire frontal snrfaee membranous. No 

 spines, no ovicell. The zoarium is membranous, nonarticulated 

 with branches, unilamellar, and multiserial. 



Genotype. — Hoplitella (Carbasea) armata Busk, 1852. Recent. 



We have introduced this genus into the Scrupocellariidae after 

 Levinsen, 1909, but it is little probable that it has been correctly 

 classified.

Fig. 85. — Genus Hoplitella Levinsen, 1909 

 A-K. Hoplitella armata Busk, 1852. A, B. Zoarium, natural size and enlarged 

 (after Busk 1852). C. Anterior face, X23. D. Basal view. The proximal 

 part of the zooecia is furnished with two long lateral expansions, but only with 

 a single one in the marginal zooecia; X23. F. The distal wall, from the proxi- 

 mal end. On each side is seen the transverse section of an expansion. The 

 occlusor muscles of the operculum are also seen, X55. E. A longitudinal section 

 through a zooecium. The bent distal wall (d. w.) and one of the expansions are 

 seen, X40. G. A Longitudinal section through a marginal zooecium. The 

 internal aspect of the avieularium (av) and the strong marginal thickening which 

 surrounds the rosette plates are seen, X40. (C-G, after Levinsen, 1909.) H, I. 

 Lateral and distal wall, X25 (after Waters, 1896). J. Operculum, X85. K . 

 Avicularian mandible, X250. (J, K. After Waters, 1885.) 



GROUP 2. OVICELL ENDOZOOECIAL 

 Genus MENIPEA Lamouroux, 1812 



(Emma Busk, 1852) 



The ovicell is endozooecial. The zoarium is articulated; the 

 segments are short, narrow proximally, formed of 2 to 5 zooecia. 

 There arc spines and a frontal avieularium. The lateral avieularium 

 is attached at the level of the proximal portion of the opesium. The 

 radicular dietella is placed above the chitinous joint.
