A New Species of Clathriid Sponge from the San Juan Archipelago
نویسنده
چکیده
In the course of investigating the cytology of clathriid sponges a new species from the San Juan Archipelago, Washington, has been found. On the basis of skeletal and field characteristics this form appears to be identical to chela-containing sponges described by de Laubenfels (1927) from California as variants of Ophlitaspongia pennata (Lambe, 1894). Cytological evidence reviewed here (see Simpson, in press, for detailed discussion) establishes that the chela-bearing sponges are not conspecific with O. pennata.
