A REPORT ON THE CYCLOSTOMATOUS BRVOZOA OF JAPAN

the centre and thickest at margin owing to superposition of two or three 

 zooecia in that part. Zooecia arranged in radial series, in the each series 

 consisting of a row of them; in the peripheral parts, rows of later origin add 

 themselves to between those which start from the center. Zooecial aper- 

 ture circular, o. 12-0. 16 mm. in diameter; provided with porous closure, 

 except those near the margin. Ovicell prominently inflated ; tubercular 

 when small, transversely elongate when larger. Ooeciostome very short, 

 situated near distal border of ovicell at nearly the center of ooecial summit 

 or somewhat laterali)' to it. Ooeciopore sub-elliptical, o. 1 x 0.04 mm. large. 

 Dorsal surface of zoarium with fine and dense wrinkles, nearly smooth.

This new species is represented in the collection by a few number of 

 colonies, which were all taken from a Hcxactinellid obtained at Okinosé, 

 from a depth of 3 1 2 fms. The species closely resembles Berenicea lineata 

 (MacGill.), but differs from it in the arrangement of zooecia and in the shape 

 of ooeciopore.

A single specimen in the collection, attached on a Hexactinellid from 

 Okinosé, 312 fms. As Busk's original description of the species is brief, it 

 is with some doubt that this specimen is identified with the above species. 

 However, so far as his description and figures go, there is a complete agree- 

 ment between the two. The ovicell of the species appears to have hitherto 

 remained unknown. The same occurs in the specimen before me in the
