NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA CYCLOSTOMATA 761 



Genus LOXOGALYX Mortensen, 1911 



In this genus the foot-gland is evident and functional throughout life. 

 Genotype Loxosoma raja Schmidt, 1876. 



Loxocalyx sp. 



Three individuals attached to the parapodia of an annelid vv^orm, 

 Gattyana cirrosa, from Puget Sound. The calyx expands abruptly, and 

 its base is rounded; width of calyx 0.26 mm, height 0.33 mm, length 

 of pedicel 0.40 mm. The foot-gland is present, but the tentacle number 

 cannot be estimated. 



Family Pedicellinidae Johnston, 1847 



Colonial, the individuals erect from a creeping segmented stolon, the 

 pedicels and stolon more or less chitinized. In the genera Myosoma and 

 Pedicellina the pedicel is muscular and flexible, w^ithout a special muscu- 

 lar enlargement at the base, while in Barentsia and Coriella the pedicel 

 is more chitinized and bears an enlarged, barrel-shaped muscular en- 

 largement at its base. In Barentsia daughter individuals are often pro- 

 duced by budding from joints of the pedicel. 



Key to Genera of Pedicellinidae 



1. Pedicels not heavily chitinized, muscular and flexible, rising 



directly from the stolon without a specialized muscular base . 2 

 Pedicels usually stiff and inflexible, with an enlarged cylin- 

 drical, somewhat barrel-shaped base 3 



2. The lophophore (tentacle crown) is diagonally placed on the 



ventral side; the pedicel thick and with strong diagonal 



muscles Myosoma 



The lophophore is terminal, the pedicel narrower and without 



diagonal muscles Pedicellina 



3. Individuals always arising from short stolon internodes; erect 



branches formed by the fusion of stolons ; pedicels never 



jointed Coriella 



Individuals arising from short stolon internodes, or from the 

 sides of the pedicels; erect branches sometimes formed by 

 enlarged pedicels; the stolons do not fuse to form erect 

 branches Barentsia
