Thophosome. Stems rising from creeping hydrorhiza to height of 
¥0 to 30 mm., with numerous short branches. Hydranths borne alternately 
on latter, on moderate pedicels; 9-11 rather stout tentacles. Stem usually 
smooth, occasionally wrinkled. Pedicels with 2 to 5 more or less indistinct

Pedicel short and smooth; spadix branched. 
Fig. 1.—Bimeria gracilis. Gonophores. 
Distribution. Dredged near the mouth of San Diego Bay, in 
3 fathoms, July, 1903; La Jolla, at low water, July, 1903. San 
Diego (Clark). 
There can be little doubt that this is Clark’s species. The 
perisare was covered with minute adhering particles. Male 
sporosaes are slightly smaller than female.
