Resumen:
Two new species of muricids belonging in the genus Trophon are described from the upper slope off the Atlantic coast of Argentina. Both species have a small size for the genus. The radulae show similarities with those of Antarctic species of the same genus. Trophon columbarioides n. sp. has a smooth shell with spines pointed adapically and was collected at 37-38°S, in 209-382 m while T. fasciolarioides n. sp. has prominent spiral cords and was positively collected at Burwood Bank in 286-292 m depth and off Bahía Blanca in ca. 1000 m depth.
