Sertularia furcata (Trask)
Both of the above forms were found on the washed-up holdfasts of Macrocystis.
Family PLUMULARIIDÆ
Aglaophenia inconspicua (Torrey '02)
Torrey's description gives "hydrocladia 3-4 mm. long." Out of a large number examined, however, I found none with hydrocladia more than 1.5 mm.
Aglaophenia struthionides (Murray)
Both A. inconspicua and A. struthionides were taken from the red algæ brought in by the tides.
Plumularia setacea (Ellis)
This form appears to have a wide variation in its bathymetric distribution. Specimens were collected from the mussels which are uncovered at mid-tide, and from the carapace of Loxorhynchus grandis, a deep-sea crab that is only rarely brought to shore by the highest tides.
Plumularia lagenifera (Allman)
