— Above the banks none or very few specimens of E. hamata 
have been. found (possibly the specimens from the stations 79a, 
81a, 424, from which the material was not preserved, have be- 
longed to this species). 
Near the coast E. hamata is not common and was never found 
in the upper strata. — In Umanak Fjord the largest number of 
specimens were found about 300 m below the surface (temp. 5 
sal. 34.1 %00), but also in greater depth (about 500 m, temp. 17.0, 
sal. 34.5 %/00) several individuals were captured. — In the Disco 
Bay 14 specimens were found at stat. 124 (150 m wire); the 
temperature was ca. — 094, the salinity 33.6 00; according to the 
journal the species seems to have been abundant in greater depth 
(stat. 125, 550 m wire), where the temperature was ca. 0.9, the sal- 
inity 34 ”/00. — At stat. 196, near Egedesminde, some few indiv- 
iduals were found at temp. 09.52, sal. 33.75 ”/o0o. — South of North- 
ern Storø (stat. 503) the temperature was decreasing from 39.44 at 
the surface to —— 0.87 in 250 m (the depth of the bottom was 265 
m). A haul with 100 m wire (temp. ca. 0%,4, sal. ca. 32.5 "/0o) 
brought no chaetognaths, while a number of E, hamata (and many 
Sagitta elegans) were captured by a haul with 250 m wire at a 
temperature of ca. +. 07.8 and a salinity of ca. 33.6 %/00, i. e. lower 
temperature and higher salinity. — In Bredefjord (stat. 545) EÉ. 
hamata was found about 200 m below the surface (temp. ca. 
3.3, sal. ca, 34.4 ”/00). — In Skovfjord (stat. 583) it: was found 
in a similar depth at temp. ca. 17,5, sal. ca. 33.9 9/00. 
From these facts we may state as follows as to the occurrence 
of Eukrohnia hamata within the area investigated by the "Tjalfe" 
expedition: In the Atlantic at a latitude of about 58—60? N big 
crowds of this species occur in the deeper strata, particularly 
at 200-—600 m below the surface, but not seldom the species 
is met with at the surface, though in much smaller numbers. Also 
in the southern part of the Davis Strait, where the surface water 
has a comparatively high salinity, the species may be found in the 
upper strata, even close to the surface, while further north, where 
the salinity of the surface water is low, the species occurs in the 
deeper strata exclusively. It is absent above the coastal banks of 
West Greenland, where the water masses of the East Green- 
land polar current, which have a low temperature and a low sal-
