NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA — CYCLOSTOMATA 673 



O'Donoghue gave no description of this species, but his illustration 

 (plate 2, fig. 12) certainly shows a Filifascigera and it may well be the 

 S. fasciculata of Hincks. The description of the species by Hincks is very 

 complete, showing the erect arrangement of the tubules in bundles, well 

 spaced and elevated, and he also figures the ovicell (plate 59, fig. 4) set 

 between the fascicles with the ooeciostome off center and separated from 

 the tubules. The ovicell has much the same appearance as that of F. 

 clarionensis new species, described above, but the ooeciostome is much 

 compressed and its pore almost slit-like. 



The only question is whether O'Donoghue's species is that of Hincks, 

 and that cannot be determined here as the species has not appeared in 

 the Hancock material. 



O'Donoghue records the species from Northumberland Channel and 

 Gabriola Pass, British Columbia, and the San Juan Islands, Puget 

 Sound. 



A specimen from southern Alaska, U. S. Fisheries Alaska Crab In- 

 vestigation, Sta. 82-40, may belong here, but in the absence of complete 

 ovicells the identification is questionable. It is a much larger species 

 than the preceding, the apertures measuring 0.16 to 0.18 mm in diameter. 

 The one ovicell is properly located for this genus, but is incomplete and 

 lacking the ooeciostome. 



? Filifascigera sp. 



Another species which probably belongs to this genus but may be a 

 Frondipora was taken at Hancock Station 1914-49, ofif Guadalupe 

 Island, west of Lower California, 28°52'N, 118°19'W, at 5-15 fms. 

 The fascicles are larger and higher than those of F. clarionensis (the 

 aperture 0.14 mm in diameter), and several fascicles sometimes arise 

 from a single base to form a complex fascicle. The peristomes usually 

 rise free above the top of the connate portion of the fascicle, as they do 

 in F. clarionensis. The ovicell lies in the space between the fascicles of 

 a complex fascicle with lobes extending among them. Unfortunately 

 there is no evidence of an ooeciostome. 



The material is too imperfect for positive identification but it is cer- 

 tainly different from either of the species mentioned above, especially 

 in the nature of the complex fascicles and the ovicell. The small fascicles, 

 usually of less than 8 tubules, would seem to remove it from Frondipora.
