| Abstract |
Two new species of Microporella are described from Sagami Bay, Honshu, Japan based on the material newly discovered in the Doderlein Collection, Musee Zoologique, Strasbourg, France. Microporella serrata sp. nov. is characterized by having a pyramid-like, high trigonal umbo hanging over the ascopore on the zooid front, and a depressed-semicircular orifice with a denticulate distal edge. Microporella unca sp. nov. is unique in having beaked mandibles, similar to those of "the bird's head type" avicularia in the Bugulidae. The evolution of two different types of avicularian mandibles in the genus is briefly discussed from functional and ecological points of view. |
