Abstract
Two new acoels, one new alloecoel, one new marine triclad, and one new polyclad, are described from the Atlantic coast of North America. 2. The acoels are Afronta aurantiaca, family Proporidae, and Ectocotyla paguri, new family Ectocotylidae, both from the Mt. Desert Island region, Maine. The former lacks frontal glands and accessory female structures. The latter is one of the most remarkable acoels yet discovered, having a protrusible plicate pharynx and caudal adhesive disk provided with adhesive papillae; it also appears to be viviparous. It is epizoic on the hermit crab Pagurus pubescens. 3. Plagiostomum album, also from the Mt. Desert Island region, is described. 4. The marine triclads Procerodes littoralis (Ström), 1786 (= Procerodes ulvae), and Foviella affinis (Oersted), 1925, are reported from Brigus, Newfoundland; hence these species are distributed in the North Atlantic from Newfoundland to Scandinavia. Procerodes wheatlandii Girard, 1850, found on the Massachusetts coast, is considered to be at best a geographic variant of P. littoralis. 5. A new marine triclad, Probursa veneris, new family Probursidae, [from the] shores of Long Island, New York, differs from all known triclads in the far posterior position of the ovaries and differs from all other marine triclads in having the copulatory bursa situated anterior to the penis bulb. 6. A new polyclad, Comprostatum insularis, family Cryptocelidae, is described from the Florida keys"--P. 8.
