BRYOZOA OF THE PHILIPPINE REGION 185 



Genus FARCIMINELLUM Harmer, 1926 



Branches pluriserial, bilaminar, flattened, with at least 3 series of 

 zooecia on each face, those of the basal surface being kenozooecia, 

 without orifice or operculum, with the exception of the marginal row 

 on each side. Median and lateral zooecia differentiated, as in 

 Himaiitozoum (Bicellariellidae), their proximal ends not conspicu- 

 ously forked, and hardly overlapping their predecessors. Spines 

 and avicularia present or absent, the mandibles rounded. Ovicells 

 present (F. alice) or large eggs in the zooecial cavity, correlated with 

 the absence of ovicells as in Himantozoum. 



Genotype. — Farciminaria hexagona Busk, 1884. Recent.

This charming little species is well known. The segments are 

 rather variable. The zoarium is attached to marine algae, forming 

 thick bushes. The recognition of the depth in which the dead seg- 

 ments are found is not yet useful. The species does not appear to 

 occur far from the shore. It is a tropical species and has already been 

 noted in the Philippines. Its presence in the fossils is an exact 

 method to indicate the variations of the tropics. Waters has noted 

 that the ovicell is visible with difficulty.
