The two vertical hauls collected at this time, one from 15 and the other 
from 25 fathoms, measured respectively 13 and 16 ¢.c.’s. The contents of 
both gatherings consisted chiefly of the species mentioned. Anomalocera 
patersont and Centropages hamatus were also present, but they formed 
only about I per cent. of the whole catch. A small number of Hvadne 
norimanni, young Decapoda, and Schizopoda were also observed. 
AUGUST AND SEPTEMBER.—The samples collected in August and Sep- 
tember were very small, and showed a considerable decrease in the number 
of pelagic crustacea at this station. The contents of the various gather- 
ings consisted almost entirely of Calanus. 
NovEeMBER AND DECEMBER.—There was a somewhat similar absence of 
pelagic crustacea at this station when visited in November, but in 
December a distinct, though not very extensive, increase appeared to have 
taken place, especially in the deeper water. A vertical haul from 28 
fathoms collected in December measured 2° 5 c.c.’s, and consisted chiefly of 
Calanus. 
STATION V. (MIDWAY BETWEEN PENNIMORE AND Newton Bay). 
Forty-three gatherings were collected at this station in 1905, twenty- 
one in 1906, twenty-one in 1907, and HDs in 1908, and are briefly 
described below. 
1905. 
JANUARY.—The gatherings collected at this station in January 1905 
comprised three horizontal and four vertical hauls. The horizontal 
gatherings collected at the surface and at 15 and 30 fathoms were all 
moderately large. The surface gathering measured 152 c.c.’s, and con- 
sisted almost entirely of Calanus. One or two other species, including 
Pszudocalanus and Acartia clausi, were also noticed, but they occurred 
very sparingly. The other two gatherings from 15 and 30 fathoms 
measured respectively 60 and 43 c.c.’s. The vertical hauls were from 15, 
30, 45, and 59 fathoms, and measured respectively 12, 24°5, 30, and 35 c.c.’s. 
Calanus formed the largest portion of the contents of these hauls, and the 
quantities captured showed them to be fairly plentiful all through the 
water. 
Marcu.—The gatherings collected in March showed that Calanus were 
still fairly abundant and more or less evenly distributed at the vavious 
depths represented by the different hauls. The four vertical hauls collected 
at this time were from 15, 30, 45, and 59 fathoms, and measured 18, 19, 
26, and 25 c.c.’s respectively. In the haul from 59 fathoms a few 
Nyctiphanes were observed, but otherwise the contents of the different 
gatherings appeared to consist entirely of Calanus. 
ApRIL.—Five of the gatherings collected in April were horizontal hauls 
and four were vertical. One of the horizontal hauls was taken at the 
surface, one at 15, 30, and 45 fathoms, and one near the bottom. The 
surface gathering was comparatively small, but the next three were large. 
They measured respectively 5°5, 110, 87, and 65 c.c.’s; their contents 
consisted almost entirely of Calanus, the only other species observed being 
a few Pseudocalanus, Centropages hamatus, Acartia clausi, and a small 
number of Decapod larve. The bottom gathering contained a quantity of 
mud, mixed up with which were several Molluscan shells, chiefly Lamelli- 
branchs and the undernoted crustacea—Leptognathia brevimana, Harpinia 
pectinata, Campylaspis costata, and a few Calanus. 
The vertical hauls were from 15, 30, 45, and 60 fathoms, and measured 
respectively 5,13, 19, and 22-5 c.c.’s, The contents of these gatherings 
did not differ much from the others, except that in the haul from 60
