A few spec- imens incl. ovigerous $. but determination not certain, for antenna 1 (and several other limbs) are lost. Remarks. Accessory flagellum has a minute apical joint and is rather long, as long as or a trifle longer than the long first joint in flagellum. G. 0. Sars (1895) writes: "length of adult female 7, of male 8 mm. Maximum length of Arctic specimens 12 mm". In the "Ingolf" collection there are, however, specimens of lengths up to 14 mm. I have dissected two of these large specimens ($ and $; "Ingolf" St. 15) and give drawings (Fig. 21) of some of the limbs. They agree fairly well with Sars 1. c, but there are some differences, probably d
