Part III. — Twenty-seventh Annual Report 



hauls were from 15, 30, 46, and 60 fathoms, and one from the bottom, 

 and measured respectively 11*5, 1 7, 20, 40, and 45 c.c.'s. All the gathering?, 

 both horizontal and vertical, consisted for the most part of Calanus, but a 

 number of Euchaita norvegica occurred in those from the deep water. 



March. — The three horizontal gatherings collected in March were from 

 the surface, mid-water, and bottom. The first was nearly blank and 

 contained only a few Calanus and fish eggs. The other two, which were 

 also comparatively small, measured about 14 and 20 c.c.'s respectively. 

 The mid-water gathering consisted for the most part of Calanus, but in 

 that from the bottom Euchaita were nearly as numerous as the Calanus. 

 Xyctiphanes was also sparingly represented, as was also the somewhat rare 

 Campylaspis rubicunda. 



The vertical hauls were taken at intervals of about 15 fathoms, as in 

 January, but on this occasion the hauls were duplicated, two being made 

 at each interval. They were small gatherings, and ranged from less than 

 1 to 3 c.c.'s. Their contents consisted for the most part of Calanus. 



April. — Eleven gatherings collected at this station in April yielded 

 some interesting results. A horizontal haul taken at the surface measured 

 only about 3 c.c.'s; one taken at about three fathoms below the surface 

 measured 325 c.c.'s, and, like the other, consisted almost entirely of 

 Calanus. The other hauls from 18, 33, 48, and 75 fathoms measured 

 respectively 60, 3, 5 5, and 16'5 c.c.'s. The result of these hauls showed 

 that Calanus was in much greater abundance near the surface than in 

 the deep water. 



The vertical hauls were taken at the saine intervals as before, the last 

 being from 75 fathoms. Their contents, which measured respectively 5*5, 

 4, 9, 4, and 4 c.c 's, were similar to the hauls collected horizontally. The 

 other species observed included Pseudocalanus, Centropages hwnatus, Acartia 

 clausi, and Euchaita norvegica, but these occurred only in small numbers. 



May. — Three horizontal and four vertical hauls were collected in May. 

 The first three included a surface, mid-water, and bottom gathering, and 

 measured respectively 15, 24, and 60 c.c.'s. The vertical hauls were from 

 15, 30, 45, and 74 fathoms, and measured respectively 9, 9*5, 12, and 42 

 c.c.'s. These hauls show a gradual increase in the quantity of pelagic 

 Crustacea from the surface downwards. The contents of the different 

 gatherings, like those collected in April, consisted chiefly of Calanus, 

 and were otherwise similar to them. 



June. — The gatherings collected in June comprised three horizontal and 

 five vertical hauls. The surface gathering was very small and measured 

 only 1 c.c, but the other horizontal gatherings from mid water and bottom 

 contained a moderate quantity of pelagic Crustacea, and measured respec- 

 tively about 50 and 75 c.c.'s. The vertical hauls were comparatively 

 small; they measured respectively 4*5, 7, 12, 9*5, and 14*5 c.c.'s, and 

 consisted, like the others, almost entirely of Calanus. 



August. — Vertical hanls from 15, 30, 45, and 60 fathoms were collected 

 in August, and measured respectively 3*5, 5*5, 11*5, and 22*5 c.c.'s. 

 Calanus was almost the only species observed in these gatherings. 



September. — The gatherings collected in September were also all vertical 

 hauls. One was taken at 15 and 30 fathoms, two at 45 fathoms, and one 

 at 60 and another at 75 fathoms. The gatherings from 15 and 30 

 fathoms measured respectively 4'5, 5 c.c.'s, one of the gatherings from 45 

 fathoms 4*5 and the other 9 c.c.'s, while those from 60 and 75 fathoms 

 measured respectively 75 and 125 c.c.'s. All these gatherings consisted 

 chiefly of Calanus. Some other species, including Pseudocalanus elongatus, 

 Bradyidius armatus, Euchibta norvegica, Acartia clausi, Rhoda j-aschi, 

 Xyctiphanes, and Sagitta were observed, but they occurred very sparingly. 



October. — Five vertical hauls were collected in October. The first 

 three gatherings were very small, and measured respectively 1, 1, and 1-5
