ResumoBecause of the small size and sporadic occurrence of archiannelids, the genus Dinophilus has received scant attention in this country. D. pygmaeus was studied by Verrill in 1892 from New England, but due to the inadequacy of the description, this species must be considered invalid. D. simplex, another form which Verrill considered as belonging to this genus has been transferred to the turbellarian genus Alaurina. D. gardineri was studied and reported on by Moore (1899) in a preliminary note. Ruebush (1940) established the validity of this species in a careful and thorough study of material from the type locality, Woods Hole, Massachusetts. Nelson (1907) made detailed studies on a New Jersey species which he considered new and named D. conklini. Shearer (1912), Fauvel (1927), Hempelmann (1931) and Remane (1932) all consider D. conklini to be at most no more than a geographic variant of D. gyrociliatus Schmidt. Thus D. gardineri Moore and the European form D. gyrocilialtus Schmidt ( = D. conklini Nelson) are the only species of this genus reported from the United States. We have reported (Jones and Ferguson 1949, 1951) two other Dinophilids, D. kincaidil from Washington on the Pacific Coast and D. jagersteni2 from the Virginia-Carolina area of the Atlantic Coast, but the present paper gives the first published description of these forms.
