Gammarus wilkitzkii is a circumpolar, arctic species found from the Arctic Ocean south to Newfoundland. Females produce a single large brood of large eggs in the autumn or early winter which hatches and is released from April to July. The species matures at a relatively large size.Gammarus stoerensis is an Atlantic amphiboreal species found from eastern Nova Scotia south to Rhode Island. It is a small species and females produce a series of small broods of small eggs between the spring and autumn, but are in the resting stage between then and late winter.Gammarus mucronatus is found from southwestern Newfoundland south to the Gulf of Mexico. It is a small species and produces a low number of small eggs in each of several summer broods.

The archaeology of Minnesota is of interest for three principal reasons. Its geographical situation near the center of the continent, where it is the only state having drainage to the Arctic Ocean, the Gulf of St. Lawrence and the Gulf of Mexico, gives it importance in the consideration of migrations of early man and of the late prehistoric westward movements of various Indian groups. Until recently, the archaeology of this large area was less well known than that of other areas in the region, so an increased knowledge of it will be of value in contributing to a better understanding of the known archaeological manifestations of the central and northeastern parts of the United States. Finally, over most of the state the last prehistoric remains are of the Woodland pattern, giving an especially good opportunity for a study of that pattern in a relatively unaffected form.

Unusual Finding

A new species of Pogonophora obtained from one station at a depth of 25 m from near the Dikson Island in the Kara Sea is described. Galathealinum karaense sp. nov. is one of the largest pogonophorans, the first known representative of the rare genus Galathealinum Kirkegaard, 1956 in the Eurasian part of the Arctic Ocean and a highly unusual finding for the desalted shallow of the Yenisey Gulf. Several characters occurring in the new species are rare or unique among the congeners: under-developed, hardly discernible frills on the tube segments, extremely thin felted fibres in the external layer of the tube, and very faintly separated papillae in the anterior part of the trunk. Morphological characters useful in distinguishing species within the genus Galathealinum are defined and summarised in a table. Diagnosis of the genus Galathealinum is emended and supplemented by new characters. Additionally, three taxonomic keys are provided to the species of Galathealinum and to the known species of the Arctic pogonophorans using either animals or their empty tubes only, with the brief zoogeographical information on each Arctic species.
