Unidentified genus sp. B

New undescribed species record for Gulf of Mexico, based on specimens from USNM 79399, 88117, 88118, 88121, 88123, 88126-88130, 88132, 88133, 88137 examined by J. Pilger; distinctive palmate projections on proboscis near base and on trunk, internal organs not always visible; possibly Anelassorhynchus sp.; Fisher (1946: 222) challenged genus suggesting that projections on base of proboscis cited to establish genus may be adaptations to extreme environments, if true, this species is found in near-shore environments and may experience potential estuarine conditions caused by lateral transport of fresh water emerging from the Mississippi Delta.
