. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. BRACHIOJfODA 13. Chart *. Distribution of Dallina septigera (Lov.). 1 spec. Between Iceland and the Fan 'Ineolf" St. 3; 63°35'N. 10°24'W.; 512 m; 2 spec. Small ovate shells with large, widely spread punctae. The fully grown shells are superficially seen much like young shells of Wald- heimiathyris cranium. They may however easily be distinguished by the presence of a septum of which no remains are left in the adult shells of Waldheimiathyris. The septum of D. spitzbergensis is short and triangular, situated in front of the middle of the valve; to the slightly elevated upper edge of it the brachial loop is attached by short connecting bands. The foramen is longitudinally oval. The present finds are all within the area of distribution hitherto known and thus offer nothing of interest besides the fact that some of them are from considerable depths. The species is widely distributed in the arctic and boreo-arctic zones as marked on the chart. According to Davidson (1885, p. 84) it has been dredged on the Channel slope between Cape Clear (Ireland) and Ushant (Brittany) and off the Scilly Islands. Jeffreys (1878, p. 409) reports it from Cape Vincent in southern Portugal. In consideration of the otherwise arctic and boreo- arctic distribution of the species a reexamination of the lusitanian specimens seems desirable. Dallina septigera (Loven).
