NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA CYCLOSTOMATA 669 



both of the supporting column and of the head. Ooecium an inflation 

 of the surface of the head. Ooeciostome and ooeciopore slightly com- 

 pressed, opening beside the zooecial aperture." Orca, Prince William 

 Sound and Sitka, Alaska. 



O'Donoghue listed it from several localities in British Columbia. 



Entalophora sp. 



Zoarium slender, nearly straight, 4 or 6 tubules constituting the stem, 

 width 0.75 to 0.90 mm ; the peristomes elongate, nearly at right angles 

 to the stem axis, perforated like the tubules nearly to their tips. On the 

 surface the tubules are more or less distinct, the whole surface trans- 

 versely wrinkled and perforated with small pores ; on the older part of 

 the stem the peristomes also are wrinkled on the basal portion. There 

 is a tendency toward spiral arrangement, though 2 or 3 peristomes may 

 arise at nearly the same level. Width of stem 0.75 to 0.90 mm; width 

 of tubules on the stem 0.30 mm; width of apertures 0.16 to 0.20 mm; 

 longest peristome 0.65 mm but the average about 0.25 mm. 



The specimen consists of part of a stem 20 mm in length, both base 

 and tip wanting and without an ovicell. It has some resemblance to 

 E. proboscideoides Smitt, 1872:11, but it is much larger, the apertures 

 nearly twice as broad. The large size of the tubules, the width and 

 length of the peristomes and the coarse transverse striation of the stem 

 seem to indicate it as an undescribed species, but in the absence of an 

 ooecium I hesitate to give it a name.

Entalophora raripora d'Orbigny is listed by Robertson 1910:256 from 

 Monterey, California, and by O'Donoghue, 1923:13, from several 

 places in British Columbia. 



Entalophora clavata Busk is also recorded by O'Donoghue, 1923:13, 

 from several British Columbia localities. 



Entalophora vancouverensis O'Donoghue, 1923:13, is described and 

 recorded for Cardale Point, Round Island, British Columbia. From its 

 appearance as judged by figure 7 (plate 1) it may be a species of Bi- 

 entalophora, but O'Donoghue does not mention the presence of kenozoids 

 on the stalk. 



The Entalophoras are evidently much in need of a thorough restudy.
