Only once taken by the "In- golf": W. Greenland: St. ,54: 65 17' N., 54°i7' W., 104 m., 1 spec; but the Copenhagen Museum pos- sesses specimens from a number of localities in W. Greenland from abt. 6o° N. to abt. 730 N.: Brede- fjord, "Rink" St. 32, 35—37 m., 1 spec. (K. Stephen- sen 1916, p. 286: T. nanoidcs}) — Sukkertoppen, 4 —6 m., "Fylla" 1886, Th. Holm leg., 1 spec. — Uper- nivik, the harbour, abt. 20 m., stones with algse, "Fylla" 1886, Th. Holm leg., 7 spec. — In addition we have from old times a number of specimens from Greenland without special locality. — The following specimens are probably to be referred to the present species. Cape Borlase Warren (, abt. 73 Vs" N.), on the anchorage, II. Amdrup-Kxped. 14-7-11)00, 23 ad. 11—12 mm., 3? (2 with ova abt. 9—10 mm., 1 without ova, abt. 8 mm.).— Jan Mayen, "different depths", II. Amdrup- Exped. 1900, Soren Jensen leg., 2 $ ad. (with calceoli) 8 mm. - The specimens from Cape Borlase Warren (fig. 25) differ from the type specimens in the following characters. Eyes quite invisible. Ant. 1 in $ has fla- gellum 17-articulate, accessory flagellum 5—6-articulate (in the case of being 5- articulate the two proximal joints have coalesced). In + with ova the figures are 12 and 5 respectively, and the first joint in flagellum
