Station 2195, Albatross; 300 males and females and many development stages at various stations of Grampus in Gulf of Maine. Distribution.—Finmark and Norwegian coast (Sars) ; North Atlantic ( C 1 e v e ) ; Greenland, Spitzbergen (Kr0yer, Lilljeborg) ; North Sea (Buchholz); Baffin Bay (Norman); Jan Mayen Island (Sars); Arctic seas (Mrazek); Bering Strait (van Breemen) ; Barents Sea, Davis Strait (Vanhoffen, Stej^hensen) ; Denmark Strait, Iceland, Faroe Channel (With). —Entirely transpar- ent except two elongate red spots on the midline nearer the ventral surface. One of these is near the middle of the cephalic segment, the other at the posterior end of the body. The bases of the first antennae are transpar- ent ; then two longitudinal red stripes become distinguishable under a hand lens and extend a little more than half the entire length of the antennae. They are followed by a single stripe running half the remaining distance, and the tips are colorless and transparent like the base (Eathbun). Female.—Head separated from the first segment; fifth segment pointed at its posterior corners; first antennae extending for about three segments beyond the tips of the caudal rami. First basipods of fifth legs elongated and irregularly toothed on their inner mar- gins. Total length, 7-10 Please note that these images are extracted from scanned page images that may have been digitally enhanced for rea
