The polychaete genus, <i>Acrocirrus</i>, from Japanese waters

[None. Introduction as follows:]
In 1872 Grube instituted the genus Acrocirrus for the reception of Acrocirrus frontifilis and placed it in the family Cirratulidae. Since that time, so far as the present writer is aware, only two species have been described, i.e. A. varidus by Marenzeller (1879), from Enoshima, Japan, and A. crassifilis by Moore(1923), off Santa Cruz Island. Recently the writer has had the opportunity to examine examples of Polychaeta collected from several localities in Japan, such as Misaki (Kanagawa Pref.), Muroran (Hokkaido) and Akkeshi (Hokkaido), and found among them three different species of Acrocirrus, including A. varidus and two new forms, Acrocirrus uchidai n. sp. and A. muroranensis n. sp. The former new species is named in honour of Professor Tohru Uchida, from whom I have received valuable advice and by whose kind guidance the present study has been carried out. I am also indebted to Mr. M. Eri of the Misaki Marine Biological Station, through whose kindness the material from Misaki was placed at my disposal. Detailed anatomical and histological notes of these worms will be given in another paper.
