STUDIES ON MARINE BRYOZOA. IV. NOLELLA BLAKEI N. SP

Perophora viridis, collected from Martha's Vineyard, Mass., and brought into the laboratory for culturing, yielded a bryozoan, Nolella blakei n. sp., which was cultured and observed alive for a time. Nolella blakei is an intermediate form whose young zoids resemble those of Arachnoidea and Arachnidium but whose older zoids are definitely Nolella. It was erected a new species on the basis of its tentacle number (8 to 12) and general zoarial and zooecial characteristics. It increases to 88 the number of bryozoans known from the general Woods Hole region.
