NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA — CYCLOSTOMATA 685 



ooeciostome is longer than usual, turned forward sharply, the aperture 

 round or slightly elliptical ; when the ooeciostome is fully developed this 

 is the most striking character of the species. 



Described from Friday Harbor, Puget Sound. O'Donoghue has also 

 recorded it from a number of localities in British Columbia at 10 to 

 25 fms. 



Hancock Collections: Clayoquot Sound, British Columbia, at low 

 tide, E. F. Ricketts, collector. 



Grisia denticulata (Lamarck), 1853 



Hincks (1884:203) reported this species from Houston-Stewart Chan- 

 nel, British Columbia, without description. As it has not been noticed 

 since on the Pacific coast it seems probable that he had another species, 

 possibly C. serrulata Osburn, which is common in that area and which 

 has some of the characters of denticulata. 



Grisia calif ornica d'Orbigny, 1853 



Crista californica d'Orbigny, 1853:599. 

 Crisia californica. Busk, 1875:8. 



What this species from "Basse-Californie" may be is altogether prob- 

 lematical, as d'Orbigny's description is so indefinite as to be useless and 

 is without illustration. Busk merely translates d'Orbigny's description 

 and questions whether it may refer to C. denticulata, which is not at all 

 likely. The name should be dropped. 



Grisia punctata d'Orbigny, 1853 



Crisia punctata d'Orbigny, 1853:600. 



This species is also entirely unrecognizable from the very short de- 

 scription and lack of figures. It was recorded from the Gulf of Cali- 

 fornia "He du Venado, mer Vermeille, en Californie." The name should 

 be dropped. 



Genus GRISULIPORA Robertson, 1910 



"Zoarium erect, dendroid, composed of internodes united by chitinous 

 joints. Zooecia tubular, disposed in several alternate rows. Ooecium 

 an inflation of the surface of an internode." (Robertson, 1910:254).
