length. The avicularia are attached opposite the proximal end of the 

 opesia. The hood-shaped ooecium is attached on the inner border just 

 above the inner spine and is turned somewhat sideways. 



Robertson gives its distribution as "several localities on the coast of 

 California and Puget Sound," and O'Donoghue records it for several 

 places in British Columbia and Puget Sound.

 885-38, San Luis Obispo Bay, California, low tide to 14 fms, and 880-38,

This species belongs to the group in which the outer corner of the 

 zooecium is strongly angulated. The angle is either continued into a short 

 spine, or it is provided with an elongated spine, jointed at its base, and 

 other spines are few or wanting. The stalk segments are highly modified 

 kenozooecia, and the stalk may be as much as 50 mm long, with a palm- 

 like cluster of branches at the top. The zooecium is not sharply narrowed 

 proximally, the membranous area extends nearly to the base and the 

 avicularia are basal in position. The primary zooecium of the branch does 

 not differ from the distal ones, except that the outer corners are not angu- 

 lated. In the absence of the stalked base with its highly specialized keno- 

 zooecia this species would undoubtedly be placed at once in the genus 

 Bugula. 



Robertson recorded the species from only one locality, "at a depth of 

 125 fathoms in the submerged valley of La Jolla," California. O'Dono- 

 ghue recovered it at 8 localities in British Columbia, 8 to 40 fms. 



Hancock Stations: 296, Agua Verde Bay, and 2186, Cabeza Ballena, 

 Lower California, Mexico, 30 fms; 1150-40, Avalon Bay, Santa Catalina 

 Island, southern California, 98 to 116 fms; 1479-42, Boiler Bay, north 

 of Depoe Bay, Oregon, intertidal; 1249-41, San Benito Islands, west of 

 Lower California; and 1249-41, Santa Cruz Island, southern California.
