up, we will find, that very nearly all the specimens have been 
found at a fairly large distance from the surface. In one case 
only it was taken at the surface (two individuals from stat. 178 
or the west. coast of ;Disco, temp. 3% sal: 32.4 Y00: — A few 
non-preserved specimens from the surface near Holstensborg (stat. 
386) possibly belong to the same species). Numerous individuals, 
on the other hand, have been captured by the ringtrawl with 150 
—450 m wire, i. e. about 100—300 m below the surface. It is 
of special interest, of course, to regard the cases, when hauls have 
been made in different depths at one and the same locality. The 
four hauls from Umanak Fjord and the hydrographical conditions 
at this locality have been mentioned in the introduction (p. 25). 
By the deepest haul, 800 m wire, 7 specimens of $. elegans were 
Captured; it is very probable that these specimens were taken, while 
the ringtrawl was hauled up through a higher water layer, where 
the species was very abundant, as is proved by the next haul 
(450 m wire), when 364 specimens were taken by a haul of the 
Same duration (30 minutes). By the third haul (150 m wire) only 
a few chaetognaths were found, and the journal points out as a 
possibility, that these specimens have remained in the net from the 
previous haul. A haul with 50 m wire caught no chaetognaths. 
It is evident, consequently, that the predominant part of the indiv- 
iduals of S£. elegans, possibly the whole crowd, at the moment in 
question has lived in the strata about 300 m below the sur- 
face, where the temperature was about 09,5 C., and the salinity 
about 34..—34.2 9/00, i. e. in the upper part of the water origin- 
ating from the deeper parts of the Baffin Bay. 
The abundance of Sagitta elegans in the deeper, salt water 
layers at the stations 503, 545, and 583 in South-Greenland has 
also been mentioned in the introduction (p. 27 and 32). The species 
was found here about 160—200 m below the surface at a salinity 
of 33..—34.4 9/00, while the temperature varied from about — 0.s 
10335 
With the exception of the two specimens from stat. 178, where 
the salinity of the surface water was about 32.4 ”/oo, the species 
Was never found at a salinity of less than about 33.6 500. 
It will be seen that the occurrence of Sagitta elegans in the 
waters of West-Greenland differs rather considerably from the oc-
