NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA CYCLOSTOMATA 771 



Genus CORIELLA Kluge, 1946 



Stolon adnate and creeping, but giving off clusters of erect stolons 

 which fuse into complex sub-colonies. The zoids arise from the fertile 

 internodes of the erect stolons in large numbers on all sides of the com- 

 plex branch. The zoids are simple and unbranched, with the usual 

 muscular basal bulbs, and the stalks are provided with scattering "pores" 

 similar to those of some species of Barentsia. 



Genotype, C. stolonata Kluge, 1946:155. 



The genus appears to be similar to Barentsia in all essential characters 

 except the fusion of erect stolons to form branches.

Coriella stolonata Kluge, 1946:155 and 157. 



The complex erect branch varies greatly from 3 to 10 or 12 stolons, 

 to a height of more than 1 cm in our specimens. The calyx is large, 

 reaching 0.80 mm high by 0.65 mm in width ; the stalk attains a length 

 of 2 mm and a diameter of 0.06 to 0.08 mm, with rather numerous 

 "pores"; the basal bulb measures 0.40 to 0.45 mm in height by 0.16 to 

 0.22 mm wide; it arises from a cup-shaped enlargement which is set at 

 an angle on the side of a fertile stolon internode. The total height of 

 the tallest zoid is 3.25 mm, but they are usually much shorter. The 

 tentacle number, according to Kluge, is 22 to 24. 



The erect clustered stolons distinguish this species from all members 

 of the Pedicellinidae. 



The only record is that by Kluge (Drifting Ice Expedition in the 

 central Arctic Ocean in the Ice-breaking Str. "G. Sedov," 1937-40).
