September. —Two vertical hauls, one from 15 and the other from 25 

 fathoms, collected in September, measured about 1*5 c.c.'s each, and 

 consisted chiefly of Calanus, and were otherwise similar to those previously 

 described. 



October. — The two gatherings collected in October under conditions 

 similar to the last measured less than 1 c.c. each, and contained only a 

 small number of Calanus, Pseudocalanus, Acartia, and Sagitta. 



1906. 



April. -The two vertical hauls collected in April 1906 were small and 

 contained a small number of Calanus, along with a few other common 

 species similar to those already recorded. 



June. — The gatherings collected in June showed a moderate increase in 

 the number of pelagic Crustacea at this station. The gathering from 15 

 fathoms measured about 3 c.c.'s, and that from 25 fathoms 6 c.c.'s. The 

 first gathering consisted almost entirely of Calanus, and the same species 

 formed about 75 per cent, of the other. A few common forms similar to 

 those already recorded were in the bottom gathering. 



August. — The August gatherings were smaller than those collected 

 in June. In that from 15 fathoms Calanus, Pseudocalanus, and Centro- 

 pages hamatus were each equally numerous, and formed about 25 per cent, 

 of the haul. Temora formed about 10 per cent., and Acartia clausi 

 nearly the same. A few Anomalocera and Decapod larvae were also 

 observed. The bottom gathering contained a larger proportion of Calanus, 

 but otherwise it was similar to the last. 



September and October. — The gatherings collected in September and 

 October were very small, pelagic Crustacea being apparently scarce during 

 these months. The species represented were similar to those already 

 described from this station. 



1907. 



April. — The vertical hauls from 15 and 28 fathoms collected in April 

 1907 measured respectively 1*3 and 3*5 c.c.'s, and consisted for the most 

 part of Calanus. 



May. — Pelagic Crustacea, especially Calanus, were apparently fairly 

 plentiful at this station in May 1907. A vertical haul from 15 fathoms 

 measured 10 and one from 29 fathoms 11 c.c.'s respectively; both 

 consisted chiefly of Calanus, but in the bottom gathering a number of 

 Pseudocalanus and Centropages hamatus were also present, the one forming 

 about 5 per cent, and the other 10 per cent, of the catch. 



June. — Two gatherings were collected in June, both of which were 

 small. That from 15 fathoms measured only 1 c.c, while the other from 

 26 fathoms measured 3 c.c.'s. Both gatherings consisted chiefly of 

 Calanus. 



September. — Gatherings from 15 and 28 fathoms were collected in 

 September ; they each measured about 2*5 c.c.'s, and, like the June 

 gatherings, consisted for the most part of Calanus. 



October and December. — Very small gatherings were obtained at this 

 station both in October and December, and in each case Calanus formed 

 the largest portion of their contents. A few other species occurred very 

 sparingly, such as Bradyidius arniatus and young Euchmta norvegica. 



1908. 



May. — Pelagic Crustacea were apparently fairly plentiful at this station 

 in May 1908, obviously due to a large increase in the number of Calanus.
