Notes:
Schizocaryum dogieli Poljansky & Golikova, 1957, was discovered in four species of the echinoid genus Strongylo centrotus from San Juan Islands, Washington, during the summer of 1960. Specimens subjected to the Chatton-Lwoff silver impregnation technique have revealed that this species has been incorrectly assigned to the holotrich order Apostomatida. The presence of a vestibulum with sparse vestibular ciliature necessitates the transfer of this species to the holotrich order Trichostomatida as defined by Corliss. The infraciliature, certain pellicular organelles and the distinctive nuclear apparatus are described in detail. A discussion of various morphological and behavioral adaptations to its commensal mode of life is included. Detailed evidence is presented justifying the systematic reassignment of S. dogieli to the order Trichostomatida.
