1905. 
Frepruary.—Four gatherings, comprising two horizontal and two 
vertical hauls, were collected at this station in February 1905. One of the 
horizontal hauls was taken at the surface and the other at the bottom, and 
measured respectively 25 and 14 c.c.’s. Both gatherings consisted for the 
most part of Calanus, but in the surface hauls the following species were 
also met with :—Hucheta norvegica, Pseudocalanus elongatus, and Oithona 
similis; a few Decapod larve and fish ova also occurred. The species 
observed in the bottom haul included Bradyidius armatus, Hucheta, 
Acartia clausi, Ephimedia obesa, Epimeria cornigera, Paratylus bispinosus, 
Nyctiphanes, and Mysis sp. 
The vertical haul from 15 fathoms consisted almost entirely of Calanus, 
and that from 28 fathoms was somewhat the same, except that a few 
species similar to those already referred to were also observed. The two 
vertical hauls were about equal, and each measured 2°5 c.c.’s. The 
quantities of these gatherings, both the horizontal and the vertical hauls, 
seemed to indicate that pelagic crustacea were rather more plentiful in the 
upper strata than they weve near the bottom. 
Marcu.—Seven gatherings were collected in March; three of them 
were horizontal and four were vertical hauls. The horizontal hauls 
included a surface, a mid-water, and a bottom gathering, and measured 
respectively 6, 10, and 30 c.c.’s, and they consisted almost entirely of 
Calanus. The vertical hauls comprised two from 15 fathoms and two 
from the bottom. The first two were very small; the other two, though 
slightly larger, were also small, and together measured less than 2 c.c.’s, 
and consisted chiefly of Calanus. A small number of Pseudocalanus were 
- also observed in the bottom gatherings. 
Aprit.—Three horizontal and two vertical hauls were collected at this 
station in April. The horizontals included a surface, mid-water, and 
bottom gathering, and measured respectively 5, 17, and 3 c.c.’s. The 
contents of the first two consisted chiefly of Calanus, but Centropages also 
occurred in both and formed about 5 per cent. of the combined catch. 
One or two other common forms were also observed in these hauls. In 
the bottom haul Calanus and Centropages were equally numerous, and — 
together formed about 70 per cent. of the gathering, and Pseudocalanus 
about 15 per cent. 
Both the vertical hauls were small, and only measured 1°5 and 1 c.c. 
respectively. The contents of these gatherings were similar in variety 
and proportion to that of the horizontal bottom haul. 
May.—The gatherings collected at this station in May comprised two 
horizontal and four vertical hauls. The horizontal gatherings were both 
small; one was from the surface and the other from the bottom. The 
vertical hauls included two from 15 fathoms and two from the bottom ; 
all the catches were small, and did not differ greatly as to quantity. The 
total catch did not exceed 4 cc.’s. The gatherings consisted chiefly of 
Calanus; other species sparingly met with included Pseudocalanus, Centro- 
pages, Parapontella, Temora, Acartia claust, Hvadne, and Podon leuckarti. 
J UNE.—Pelagic crustacea appeared to be scarce at this station in June. 
Two vértical hauls, one from 15 fathoms and one from 25 fathoms, 
measured less than ‘5 c.c. each. The most common species was Centro- 
pages hamatus, but Calanus and Pseudocalanus in about equal numbers 
also formed a considerable portion of the catch. A few Temora, Acartia 
claust, Sagitta, and Decapod larve were also observed. 
Aveust.—Pelagic crustacea, though still apparently scarce, were rather 
more numerous than in June. The variety and proportional numbers of 
the species taken in the two hauls from 15 and 28 fathoms were, however, 
somewhat similar to those obtained in the June gatherings.
