The few specimens collected by the "Ingolf" Expedition were taken in hauls through the upper strata with fairly small nets; the specimens from St. 104 were small, 2 mm, the others varied in height between 1-1 and 18 mm. The specimens taken bv the East-Greenland Expedition 1900 in vertical hauls with small nets were all very small, 2-4 mm. The specimens taken 1)V the "Thor" at two .stations east of the Wyville Thomson Ridge in May 1903 and 1904 were of considerable size, 19-24 mm high. "Thor" St. 124, , was in the Faroe-Shetland Channel; the three specimens taken there were 10, 17, and 21 mm high. The most interesting material available from the Norwegian Sea is that collected by the "Dana" in May 1934, St. 5142 and 5143, above deep water east of Iceland; the hauls were made with the 2 m ringtrawl with bag of stramin, and at St. 5143 the duration of the hauls was two hours; as seeu from the list above great numbers of Aglantha were taken at all depths between about fiOO and 16(10 metres below the surface, especially in the haul with 1900 m wire out (about 1300m below the surface); there were no remarkable differences in the size of the specimens at these different depths, almost all the specimens were large, up to 20 mm in height, with a .slight admixture of small ones. The haul with fiOO m wire out at the neighbouring St
