Pogonophora from the Indian seas

Abstract

Phylum Pogonophora is generally placed in the assemblage of enterocoelous coelomates combined by some authors under the name Deuterostomia (Beklemishev, 1944 ; Ivanov, 1955 a, c, 1956, 1960, 1963 ; De Beer, 1955 ; Petrunkevitch, 1955 ; Abrikossov, 1957 ; Alvardo, 1957 ; Marlcus, 1958 ; Hyman, 1959 ; Southward, 1963 ; and others). The apparent resemblance of Pogonophora to tubicolous Polyohaeta to which stress was laid by Hartman (1951, 1954) has been explained by Ivanov (1956) as being of only superficial nature brought about by convergences attributable to a similar mode of life in a tube.
