| Abstract | Haloceras, until now included in the Trichotropidae, is made the type of a new family, Haloceratidae, considered related to but more primitive than the Tonnoidea and the Echinospirida, on the basis of new anatomical information. The main difference from existing tonnoidean families is a more primitive nervous system and the absence of complex salivary glands. The new family shows similarities to the Trichotropidae, a family which should be included in the Echinospirida. Micropiliscus Dall, 1927, until now included in the Trochidae, is synonymized with Haloceras, and the new genus Zygoceras is introduced. Seventeen named species (ten new) and three left unnamed are here included in the family. All species live on the outer part of the continental shelf and the slope, down to about 3500 m depth. Species of Haloceratidae are known from the mid and low latitudes of the Atlantic, Indian, East and West Pacific oceans. All but one species have planktotrophic larval development and one species is known from both the Atlantic and the Indian Oceans. |
