fathoms there were a small number of Nydiphanes, Rhoda rascM, and 

 Sagitta. 



May. — Three of the gatherings collected in May were horizontal and 

 four were vertical hauls. The horizontal hauls included one from surface, 

 one from mid-water, and one from the bottom. The surface and bottom 

 hauls were both considerably larger than the other, and measured respec- 

 tively 165 and 225 c.c.'s, while the mid-water gathering measured only 

 75 c.c.'s. The surface and mid-water hauls consisted almost entirely of 

 Calanus. In the bottom haul, which was also mainly composed of 

 Calanus, the following other species were observed : — Pandalus montagui, 

 Hippolyte securifrons, Caridioji gordoni, Mysis lamoi'ncB, Janira maculosa, 

 Stegocephaloides christianiensis, and a few Pseudocalanus and Centro'pages 

 The two vertical hauls from 1 5 fathoms were nearly alike, and together 

 measured about 8 c.c.'s. About three-fourths of their contents consisted 

 of Calanus, the remainder being composed of Pseudocalanus and Centro- 

 pages hamatus. Two gatherings fi'om 30 fathoms differed considerably 

 in quantity — the one measured 5 and the other 10'5 c.c.'s — and, while the 

 larger consisted almost entirely of Calanus, only about a third of the 

 contents of the smaller belonged to that species, the other two-thirds 

 being made up of Pseudocalanus (chiefly), Centropages, and one or two 

 other common foims. The gathering from 45 fathoms measured about 

 5'5 c.c.'s, and rather more than half of the contents consisted of Calanus, 

 and the remainder of Pseudocalanus and Centropages. 



August. — A vertical haul from 15 fathoms, which measured 1'5 c.c.'s, 

 consisted chiefly of Calanus, but Centropages hamatus and typicus were 

 also observed, the first being fairly numerous ; there were also a few 

 Pseudocalanus and Acartia clausi. Two other hauls from 30 and 45 

 fathoms measured respectively 3"5 and 3 c.c.'s. Both consisted mainly of 

 Calanus, with which a few other other species were sparingly represented, 

 such as Pseudocalanus, Centrojmges hamatus, Euchceta, Bradyidius 

 armatus, Temora, Acartia, and Oithona similis, and a small number of 

 Decapod and Isopod laivse. 



September. — Four vertical hauls collected in September were from 15, 

 30, 45^ and 60 fathoms, and measured respectively 1'5, 2, 4, and 15'5 c.c.'s. 

 Besides Calanus, of which these hauls chiefly consisted^ the following 

 other species were spaiingly represented, viz. : — Pseudocalanus, JBradyidius, 

 Euchoita, Acartia clausi, Rhoda raschi, and a small number of Sagitta. 



October. — The gatherings collected in October comprised vertical hauls 

 from 15, 30, 45, and 59 fathoms. These gatherings were smaller than 

 those collected in September, and measured respectively 1, 1,3, and 7 c.c.'s. 

 The deep-water gathering, which, like the others, consisted mainly of 

 Calanus, contained also a small number of other forms, including Nycti- 

 phanes, Rhoda raschi, and Sagitta. 



1906. 



April. — Vertical hauls from 15, 30, 45, and 60 fathoms collected in 

 April 1906, measured respectively 7, 5, 16, and 12 c.c.'s. The gatherings 

 consisted chiefly of Calanus, but one or two other species were observed, 

 though only in small numbers. 



June. — The gatherings from this station collected in June comprised 

 vertical hauls at 15, 30, 45, and 55 fathoms. These gatherings measured 

 respectively 7-5, 8-5, 13-5, and 17 c.c.'s. Calanus formed about three- 

 fourths of the total catch, and Pseudocalanus nearly one-fourth. A few 

 Centrojyages, Acartia, and Sagitta were also observed. 



August. — The gatherings, three in number, collected in August were 

 from 15, 30, and 45 fathoms. They were moderately large, especially the 

 last one, and measured respectively 11, 5-5, and 67 c.c.'s. The first con-
