摘要:

The cottid genusTriglopsReinhardt, includingPrionistiusBean,ElanuraGilbert andSterniasJordan&Evermann as junior synonyms, contains 19 nominal species and subspecies, of which nine are recognized here:T. xenostethusGilbert,T. macellus(Bean),T. jordani(Schmidt),T. forficaia(Gilbert),T. scepticusGilbert,T. nybelimJensen,T. metopiasGilbert&Burke,T. murrayiGünther, andT. pingeliReinhardt. All are marine, continental shelf‐or slope‐living forms, distributed throughout northern seas in shallow to moderately deep water (generally between 20–600 m), where they feed primarily on small benthic invertebrates. Seven species are restricted geographically to the North Pacific Ocean and Bering Sea:T. xenostethus, T. macellus, T. jordani, T. forficata, T. scepticusandT. metopias; T. ncoccurs in the North Atlantic and is nearly circumpolar in the Arctic but absent from the North Pacific and Bering Sea;T. murrayioccurs solely in the North Atlantic, and Atlantic sector of the Arctic Ocean;T. pingeliis present in both the North Pacific and North Atlantic oceans as well as widespread throughout coastal waters of the Arctic. Synonymies, diagnoses and descriptions are given for all taxa, geographic distributions are plotted, and a key to the species of the genus is pr

摘要:

The relationship between sponge hosts and barnacles are investigated, and the dependence of the morphology of the barnacles on the skeletons of the sponges is shown. The evolutionary development of this group is analysed. Five genera:Archiacasta, Neoacasta, Euacasta, AcastaandPectinoacasta, are distinguished from the original genus Acasta on the basis of important morphological characteristics. The new sub‐family Acastinae is suggested for these genera. The vertical and horizontal distributions of the species of this sub‐family are studied. About 150 sponge samples, containing 26 species of these barnacles, have been examined. Eight new barnacle species have been described already in the Russian Zoological Journal. This article provides illustrations of these, and descriptions with illustrations of a further five new species. This group of sponge‐inhabiting barnacles, which is rather interesting in morphological and ecological aspects, has not hitherto been examined thoro
