NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA CYCLOSTOMATA 671 



"lamina" which Waters, 1914:842, described under B. (Entalophora) 

 regularis. The kenozooecia are smaller than the autozooecia, irregular 

 in size and form but usually somewhat diamond-shaped. 



There are no ovicells on our specimens so complete identification is 

 impossible. There is considerable resemblance to B. regularis (Mac- 

 Gillivray), the genotype, as figured by Borg (1944, plate 11, figs. 3 

 and 4), but the diameter of the apertures is distinctly smaller, the 

 diameter of the stems somewhat greater, and the peristomes noticeably 

 shorter. Since B. regularis is known only from the Australian area, it 

 seems preferable to give this California form a name. 



Type, AHF no. 123. 



Type locality, Monterey Bay, California, 36°N, 122°W, at 40 fms, 

 F. P. Shepard, collector, two fragments. 



Family Frondiporidae Busk, 1875 



The zoarium consists of an encrusting, branched, ramifying base from 

 which arise erect cylindrical fascicles which are usually separated by 

 well-marked interfascicular spaces. The ovicell is developed between 

 the fascicles, either simple or lobate, and is sometimes perforated by 

 one or more tubules ; the ooeciostome is but little elevated, in Filifascigera 

 remote from any of the zoecial tubules, while in Frondipora Borg (1926, 

 text fig. 81) shows it as a crescentic pore adjacent to the base of a tubule. 



Genus FILIFASCIGERA d'Orbigny, 1852 



"The colonies are creeping, narrow, linear, or curved. The tubes are 

 grouped in salient, orbicular, or elliptical fascicles, regularly spaced. 

 The orifices are polygonal. The ovicell is a vesicle placed between the 

 fascicles and perforated by closed tubes." (Canu and Bassler, 1929:523). 

 Genotype, Filifascigera dichotoma d'Orbigny, 1852. 



This genus has been much neglected since d'Orbigny's time and until 

 very recently has been known only as a fossil. Canu and Bassler (1928: 

 44) described F. robusta from Hawaii and found the ovicell for the 

 first time. Later (1929:524) they described two other recent species, 

 F. pluripora and F. parvipora, from the Philippines. 



The above generic description requires a few additions. The orifices 

 are not polygonal except in the fascicle and at its tip where the tubules 

 are compressed together. The free peristomes, which rise as much as 0.40 

 mm above the tips of the fascicles, are cylindrical with circular apertures, 

 all separated and curving outward. The fascicles are not always evenly
