A REPORT ON THE CYCLOSTOMATOUS BRVOZOA OF JAPAN.

This new species occurs in abundance in shallow water along the 

 Misaki coast, attached on seaweeds and stones. Specimens also exist 

 from Mera, Awa province. The species is evidently a near relative of 

 Tubulipora flabellaris Fabricius, but differs from it in the shape of 

 ooeciopore. It also agrees closely with Ttibulipora occidentalis Robertson 

 in the appearance of zoarium, but is different in the characters of ovicells.

The species is represented by numerous colonies in the collection. It 

 is quite common along the near Misaki attached on kelps and stones, to- 

 gether with other Tubulipora species. In all the specimens on hand, there 

 exist on the dorsal surface a limited number of conical processess which 

 insert their pointed ends into the substratum and thus serve as the organ 

 of attachment.

A large number of colonies, which may be identified with this species 

 were collected at shallow water along the coast of the Sagami Sea, attached 

 on stones and seaweeds. Most colonies present a fan-shaped or nearly 

 circular form 2-6 mm. across. Others are 2-6 lobed, the broad and narrow 

 lobes being radially arranged in relation to the marginally situated center 

 of the colony. The dorsal calcareous projections in the Sagami specimens 

 differ from the same in Californian specimens as described by Robertson, in 

 being elongated in radial direction and in being devoid of lateral blunt 

 processes. In the specimens from Hayama, I find the dorsal projections 

 united into a continuous transverse band, instead of being separated by 

 narrow interspaces as in the type. Ortmann has described a species from
