Two new species of Spionidae were found in soft sediments at the Guaymas Basin and Juan de Fuca Ridge hydrothermal vent fields. These new spionids are unusual in having modified notopodial spines in anterior setigers and for possessing ventral as well as dorsal branchiae. Ventral branchiae have not been previously reported for the family. The presence of modified neuropodial spines in anterior setigers allies these species with the shallow water genus Scolecolepides, however, a new genus, Lindaspio, is established because branchiae begin on setiger 2 instead of 1. The two new species, L. dibranchiata and L. southwardorum, are large, with the latter species from the Juan de Fuca Ridge, being one of the largest spionids ever reported. A previously described species, S. carunculatus, from ambient sediments on the continental slope off North Carolina has been reexamined and referred to the new genus Lindaspio. All three species are described and compared.
