necting tubes, but the difference in both these characters are 
sufficiently distinctive to constitute another species. The number 
of connecting tubes varies somewhat, there being six, seven, and 
sometimes eight from one zocecium. 
Beania longispinosa was obtained in several fathoms of water 
off La Jolla, California, growing upon rock. 
Stirparia Goldstein. 
Stirparia Goldstein, 1879 or 1880. 
Stirparia, Hincks, 1883. 
Bicellaria (part), Busk, 1884. 
Zoarium consisting of erect segmented stalks, bearing on their 
summits feathery tufts whose branches consist of zocecia bise- 
rially arranged. Zowcia of the normal Bicellarian or Bugulan 
type, v.e., turbinate, with aperture looking more or less upward, 
turned obliquely inward; or. boat-shaped, with aperture occu- 
pying almost all of the front wall, not directed upward and 
zocecia not turned inward; lower portion tubular. <Avicularia 
and owcia pedunculate. 
The diagnosis of this genus as given by Hincks (’83) is here 
amended in order to include the two types of zocecia found in 
the species from this coast, as well as the occia, of which Hincks 
makes no mention. Ocecia are abundant on all the specimens 
and are of the Bicellarian type, being pedunculate upon the inner 
side of the zocecium near the top.
