less uniform from 30 fathoms downwards, and also to be fairly abundant. 

 Above 30 fathoms they were apparently scarcely so numerous. The five 

 hauls collected at this time measured respectively 8, 16, 20, 16, and 14 

 c.c.'s. The last gathering, which was from 73 fathoms, contained a few 

 Euchceta, JS'yctiphanes, and Sagitta in addition to Calanus, which constituted 

 the chief portion of this as well as of the other gatherings mentioned. 



May. — The gatherings collected in May from 15 and 30 fathoms 

 measured respectively 8 - 5 and 8 c.c.'s, while the others from 45, 60, and 

 73 fathoms measured 20, 25, and 18 c.c.'s. The contents of the several 

 gatherings resembled those collected in April, except that Eitchceta was 

 rather more numerous in the haul from 73 fathoms, and formed about 

 3 per cent, of this gathering. A few specimens of Nyctiphanes and 

 Rhoda raschi were also observed. 



September. — Four gatherings were collected in September. The first 

 three, taken at the usual depths, were comparatively small ; the one from 

 15 and that from 30 fathoms measured 5 c.c.'s each, and the other from 

 45 fathoms 6 c.c.'s. But while these gatherings seemed to indicate that 

 pelagic Crustacea were not very plentiful down to 45 fathoms, that from 

 67 fathoms showed them to be moderately abundant towards the bottom. 

 This gathering measured 130 c.c.'s. All the gatherings consisted for the 

 most part of Calanus ; Pseudoccdanus and Acartia clausi occurred in small 

 numbers (less than I. per cent.) in the hauls from 15 and 30 fathoms, and a 

 few specimens of Nyctiphanes and Rhoda raschi in that from 6 7 fathoms. 



October.— The gatherings collected at this station in October showed 

 that the tendency of the pelagic Crustacea to crowd towards the bottom 

 was even greater than in the previous month. The hauls from 15 and 

 30 fathoms measured only 2 c.c.'s each, and that from 45 fathoms 5 c.c.'s. 

 The haul from 60 fathoms was also comparatively small, while a gathering 

 from near the bottom (77 fathoms) measured 168 c.c.'s. These, like the 

 September gatherings, consisted almost entirely of Calanus. 



December. — The gatherings collected in December differed little from 

 those just described, and showed a somewhat similar inequality in the 

 distribution of the pelagic Crustacea. The gatherings consisted chiefly of 

 Calanus. A few other species, comprising Euchaita norvegica, Rhoda 

 raschi, and Nyctiphanes norvegicus, and also Sagitta, were observed, but they 

 occurred very sparingly. 



1908. 



The number of gatherings collected at- this station in 1908 was thirty-four 

 or thirty-five. Three were collected in February, four in March, and the same 

 number in May. Five or six were collected in June, five in August, four in 

 September, three in November, and five in December, as described below. 



February. — The three gatherings collected in February were from 15, 

 30, and 45 fathoms, and measured respectively 20, 23, and 45 c.c.'s. The 

 first two consisted entirely of Calanus, no other species being observed, 

 while the third differed only in that it contained a few Sagitta. 



March. — The gatherings collected in March comprised four hauls. The 

 smallest gathering was that from 15 fathoms and the largest from 30 

 fathoms ; these two measured respectively 4 and 25 c.c.'s. The other two 

 from 45 and 60 fathoms measured, the one 17 and the other 21 c.c.'s. 

 These gatherings, like those collected in February, consisted almost 

 entirely of Calanus. 



May. — Four gatherings were also collected in May. They resembled 

 those just described in that they consisted almost entirely of Calanus, but 

 the haul from 15 fathoms was rather larger than either of the next two 

 from 30 and 45 fathoms, and was only slightly less than that from 60 

 fathoms, the measurements being as follows: — The haul from 15 fathoms 

 measured 20 c.c.'s, that from 30 fathoms 18 c.c.'s, while the others from
