A REPORT ON THE CYCLOSTOMATOUS BRYOZOA OF JAPAN. 



355 



in the collection. They were all obtained at a spot off Jôgashima, attached 

 on an example of Steganoporclla magnilabris Busk. In most of the specimens, 

 there exist the specially prominent zooecia which were described by Harmer 

 from the ' Sieboga ' specimens. The secondary abnormal zooecia have 

 distinctly mucronated aperture and are easily recognizable.

This is quite a common species along the coast near Misaki, attached 

 on stones and seaweeds. It is interesting to note that whereas specimens 

 of the species from certain localities are of a light greyish color in the fresh 

 state, those living in Aburatsubo show a bright red or a deep purplish 

 color. This is due to the presence, in the cancelli and sometimes also in 

 the ooeciostomes, of numerous microscopical algœ of the color referred to. 

 The pigment dissolves away in alcohol, imparting its color to this and thus 

 rendering colorless the immersed Bryozoa.

Of this species there are numerous colonies in the collection. The 

 localities are : Yodomi (62-78 fms.) ; shallow water along the coast near 

 Misaki ; Tokyo Bay (17-32 fms.) ; Kagoshima Gulf (70 fms.).
