BRYOZOA OF THE PHILIPPINE REGION 283 



On certain branches some tubules have a salient peristome appearing 

 like false spiramens. 



Structure. — This is absolutely identical with that of Haswellia 

 australiensis. We illustrate a longitudinal section and a transverse 

 one made between two verticels. Likewise this species lives in the 

 same localities.

Genus CYLINDROPORELLA Hincks, 1877 

 (Porinula Levinsen, 1916) 



The zooecia are cylindrical and .terminated by a long tubular 

 salient, free, peristomie; the spiramen is large salient and placed 

 at the base of the peristomie; the frontal is a tremocyst with starred 

 pores. The ovicell is hyperstomial, opening into the peristomie 

 above the operculum, smooth, with or without pores. No avicularia. 



Genotype. — Cylindroporella (Lepralia) tubulosa Norman, 1868. Re- 

 cent (Northern Atlantic). 



Hincks, 1880, abandoned his genus of 1877 and classified the 

 genotype in Porina D'Orbigny, 1848. The latter has fallen into 

 disuse, the function of the frontal pore not having been indicated; 

 it still remains a rejected genus. 



Our definition of Cylindroporella is established on the section given 

 by Osburn in 1912, which we reproduce. It appears to us best to 

 place this genus in the Galeopsidae, until the time when the studies 

 of the larva will permit the classification of the principal genera of 

 the family.
