After these hydrographical remarks I shall now give a short 
account, based on the journal, of the progress of the cruises as 
far as it is of interest regarding the present matter. The account 
should be compared with the adjacent list including all stations 
from which chaetognaths are noted in the journal. The stations 
from which the material or a part of it has been preserved are 
marked with an asterisk ("). Abbreviations: Y — young-fish trawl,

The investigations were commenced on May 12th 1908 at Lat. 
599 25' N, Long. 22956" W. During the sailing towards the west 
a series of pelagic hauls was carried out. From the first station 
to the longitude of Cape Farewell 16 hauls were made. Sagittas 
are noted from 12 hauls. 3 of the four hauls by which no chaet- 
ognaths were found are surface water hauls between Long. 30? 40' 
and 34" 41” W. At the first station one specimen of Sagitta plank- 
tonis was taken by the young-fish trawl with 175 m wire"). With 
this exception the whole of the preserved material from this first 
Series of stations belonged to the two species Sagifta maxima 
and Eukrohnia hamata. It will be noticed that both species are 
numerous in the deeper strata, while the surface water contains 
few or no chaetognaths. In the preserved material from the sur- 
face I have only found E. hamata. 
From May 3lst to June 7th some pelagic hauls were made 
South-west of Cape Farewell and in the southern part of the Davis 
Strait, the course following the edge of the field-ice which in 1908 
had a considerable extent and filled up the sea to a great distance 
from the coast. Chaetognaths were quite absent in the neighbor- 
hood of the ice. Within this space of time they were only found 
at two stations, both in some distance from the ice: at stat. 19 a 
number of S. maxima and E. hamata were taken with 200 m 
Wire; from stat. 23 "one large Sagitta" (which probably means S. 
maxima) is noted as being found at the surface (temp. 29.85, sal. 
34.69 9/00). 
From stat. 30 the course was made inwards towards Fylla's 
y According to the leader of the expedition the depth in which the nets 
are -fishing may as a rule be calculated as about ”/s of the length of the 
wire used.
