93 Part [11.—Twenty-seventh Annual Report 
45 and 60 fathoms measured respectively 19 and 21 c.c.’s. These gather- 
ings showed that the distribution of Calanius was fairly uniform from 15 
fathoms downwards. 
JuNnE.— The gatherings collected in June showed a moderate increase in 
the various catches except that from 30 fathoms, which amounted only to 
about two-thirds of that for May from the same depth. The gatherings 
from 15, 30, 45, and 60 fathoms measured respectively 29, 11, 30, and 32 
c.c.’s. Two other hauls from 78 and 80 fathoms measured each 50 c.c.’s. The 
contents of these various hauls were similar to those previously described. 
Aveust.—The five hauls collected in August exhibited still further 
changes in the distribution of the pelagic crustacea, and there also 
appeared to be a falling off in the number of these organisms in the upper 
strata, and at the same time a marked increase towards the bottom of the 
loch. While the gatherings from 15, 30, and 45 fathoms measured 
respectively 6:5, 13:5, and 23°5 c.c.’s, those from 60 and 75 fathoms 
measured, the one 41 and the other 100 e.c.’s. 
SEPTEMBER.——All the gatherings collected in September were small, 
showing that a considerable decrease in the number of pelagic crustacea 
all over the loch had taken place since the station was visited in August. 
The hauls, taken in the same order as before, measured respectively 2:5, 2, 
3, and 6 ¢,c.’s, and though Calanus continued to be the more common 
species, there appeared to be a larger number of Hucheta present, 
especially in the haul from 60 fathoms. In this haul Hucheta formed 
about 1 per cent. of the gathering. A few specimens of Pseudocalanus 
were also observed, as well as a small number of Sagitta. 
NovEMBER.—Three vertical hauls were collected in November. One 
from 15 fathoms was nearly blank. A gathering from 45 fathoms was 
also small, and measured only 1 c.c. It consisted chiefly of Calanus, 
together with a small number (about 2 per cent.) of Hucheta norveqica. 
A third haul from 60 fathoms was moderately large, and measured 20 c.c.’s, 
and, like the others, it consisted for the most part of Calanus. <A few 
Euchuta, Rhoda raschi, and a small number of Sagitta were also present. 
DrEcEMBER.—-The gatherings collected in December from 15 and 30 
fathoms measured only ‘5 and 1°5 c.c’s., that from 45 fathoms was some- 
what larger, and measured 6°5 c.c.’s. Below this pelagic crustacea were 
met with in considerable abundance; hauls taken at 60 and 70 fathoms 
measured respectively 47 and 90 c.c.’s. 
OTHER GATHERINGS EXAMINED. 
A few gatherings were collected in the vicinity of Skate Island in April 
1905 and June 1906. The former comprised three horizontal hauls and 
five vertical ones, and the latter, four hauls, which were also vertical. 
Three vertical hauls were also taken off Minard, two in March and one in 
November 1908. All these gatherings, collected with the usual tow-nets, 
did not differ greatly in their contents from those taken in other parts of 
Loch Fyne. 
In October 1906 several hauls were made off Inveraray and also off 
Newton with a large “ mid-water” net, and considerable quantities of 
Calanus, Eucheta norvegica, Nyctiphanes norvegicus, and Rhoda raschi were 
captured, but with the exception of a quantity of Sagitta little else was 
observed in these gatherings. 
The following tables show the number of vertical hauls collected at each 
of the six stations mentioned in the preceding notes, the year and month 
when collected, and the depth from which the various hauls were taken. 
The quantity of each haul is also stated, in most cases in cubic centi- 
metres (c.c.’s), but some hauls which measured less than | ¢.c. are marked 
“sm.”—small. The horizontal hauls are left out, as no such gatherings 
were taken after 1905.
