of the Fishery Board for Scotland. 88 
sisted of Calanus and Pseudocalanus in about equal numbers; in the 
second Calanus formed about 50 per cent., Pseudocalanus and Centropages 
hamatus, which were nearly equal, formed together about 36 per cent., 
and Acartia clausi 14 per cent. The third haul consisted almost entirely 
of Calanus, but a small number of Lucheta (about 1 per cent.), and 
about a dozen specimens of Rhoda raschi and one or two Nyctiphanes, 
were also observed. 
SEPTEMBER.— Vertical hauls from 15, 30, 45, and 60 fathoms were 
collected in September, and measured respectively 3°5, 4, 5, and 24 c.c.’s. 
These gatherings, which were similar to those previously described, con- 
sisted for the most part of Calanus. 
OcroBeR.—The October gatherings were smaller than those just 
described. The hauls from 15 and 30 fathoms measured only 1 and 1°5 
c.c.’s respectively. The others were larger, and measured, the one 5 and 
that from deep water 16 c.c.’s. The contents of the various hauls resembled 
generally those described for August. 
Besides the four vertical hauls just referred to, other two horizontal 
gatherings were collected, one from 20 fathoms and the second from 
between 40 and 50 fathoms. Both of these gatherings contained a large 
quantity of pelagic crustacea, comprising Calanus, Eucheta norvegica, 
Rhoda raschi, and Nyctiphanes, this last species being abundant in the 
deep-water gathering, the contents of which nearly filled a large drop- 
jar. 
1907. 
Aprit.—The only gathering from this station examined in April 1907 
was from deep water, 55 to 60 fathoms, and measured 70 c.c.’s._ It con- 
sisted almost entirely of Calanus. 
May.—tThe gatherings collected in May 1907 were from 15, 30, 45, and 
58 fathoms, and measured respectively 17, 18, 15, and 21 c.c.’s. Besides 
Calanus, which formed the largest portion of the various gatherings, 
there were also a fairly large number of one or two other common species. 
Centropages hamatus, for example, formed fully 5 per cent. of the haul 
from 15 fathoms, and about 15 per cent. of the one from 30 fathoms, 
and it was also represented, though somewhat sparingly, in the gathering 
from deep water. Pseudocalanus formed about 5 per cent. of the gather- 
ing from both 30 and 45 fathoms. The same species, along with 
Nyctiphanes and Sagitta, occurred also in the gathering from 58 
fathoms. 
J unE.—Moderately large hauls were also obtained in June, especially 
from 30 fathoms downwards. The gathering from 15 fathoms was the 
smallest, and measured 6 c.c.’s, but the others measured respectively 13, 15, 
and 15 c.c.’s. The contents of these gatherings consisted for the most 
part of Calanus. 
SEPTEMBER.—The gatherings collected in September were also moderately 
large, and measured respectively 9, 22, 19:5, and 90 c.c.’s.. Their contents 
were similar to those of the June gatherings. 
Octoser.—A considerable falling off in the numbers of pelagic erastaices: 
appears to have taken place since the previous visit to this station. The 
gatherings collected in October were small, especially that from 15 
fathoms, which measured only 1:25 c.c.’s; the others, which were rather 
larger, measured respectively 6, 9:5, and 19 c.c.’s. 
DercemBerR.—A _ still further decrease was shown by the gatherings 
collected in December. These, with the exception of one from 
the deep water, only contained a small number of Calanus and one 
or two other common forms. The deep-water gathering measured 13 
C.c.’s,
