| Abstract |
A new species of the lucinid bivalve genus Lucinoma is described from shells dredged at depths of 240–500mfrom the edge of the continental shelf off southern Newfoundland. It differs from the other northern species, Lucinoma filose, in shape, ligament, and characters of the anterior adductor muscle scar. It also differs from the poorly known Lucinoma atlantis from the outer shelf off Maryland that is longer than high and has both anterior and posterior sulci, and from L. blakeana from deep water off North Carolina, a smaller species with a truncate posterior margin. Other Lucinoma species are recorded further south in the northern Gulf of Mexico, particularly from hydrocarbon seeps, although the taxonomy is confused for those taxa. |
