1908. 



February. — The gatherings collected in February 1908 were moderately- 

 large, and measured respectively 9, 20, 31 '5, and 55 c.c.'s. The contents of 

 the first three consisted entirely of Calanus, with the exception of a few 

 fish ova which occurred in the one from 30 fathoms. The same species 

 also constituted the largest portion of the deep-water haul, but in this 

 gathering a few Rhoda raschi, Leptomysis gracilis, and a small number of 

 Sagitta were also present. 



March. — Gatherings from 15. 30, and 45 fathoms collected in March 

 measured respectively 16, 20, and 26 c.c.'s. In these gatherings Calanus 

 was almost the only species observed. When compared with the February 

 gatherings, those for March show a slight decrease in the quantity of 

 Crustacea captured. 



May. — -The gatherings collected in May, like those just described, con- 

 sisted almost entirely of Calanus, which appeared to be still fairly plenti- 

 ful at this station. These gatherings, taken in the same order as before, 

 measured respectively 14, 35, 42, and 40 c.c.'s. 



June. — The June gatherings were considerably smaller than those 

 collected during the previous month, but their contents were somewhat 

 similar. They measured respectively 3, 3*5, 6, and 12 c.c.'s. 



August.— The gatherings — all vertical hauls like the othei-s — collected 

 in August, were large, and showed that Calanus, of which their contents 

 chiefly consisted, were fairly abundant. The measurements of the various 

 hauls, stated in the usual order, are as follow : — That from 15 fathoms 

 measured 5*5 c.c.'s, that from 30 fathoms 18"5 c.c.'s, that from 45 fathoms 

 25 c.c.'s, and the bottom haul 45 c.c.'s. 



September. — The four September gatherings were small. The one 

 from 15 fathoms contained about ninety Calanus and five or six Acartia 

 clausi ; that from 30 fathoms contained 364 Calanus, three or four 

 Pseudocalanus, and Acartia, while the other two from 45 and 60 fathoms 

 measured respectively 2 and 15*5 c.c.'s, and consisted entirely of Calanus. 

 A few Sagitta were observed in the gathering from 30 fathoms. 



November. — Pelagic Crustacea were apparently very scarce at this 

 station in November. Three gatherings from 15, 30, and 45 fathoms 

 contained only a small number of Calanus and a few other common forms. 



December. — The December gatherings showed a slight increase in the 

 number of pelagic Crustacea, especially in those from 45 and 60 fathoms. 

 These gatherings, stated in the usual order, measured respectively sm. 1, 9, 

 33'5 c.c.'s. Calanus formed the chief portion of their contents, but in 

 the bottom gathering Rhoda raschi formed about 10 per cent, of the catch, 

 which also contained a few Euchceta and Sagitta. 



Station YI. (off Douglas Water, and distant N. by E. from 

 Strachur 1 Mile). 



About one hundred and forty-three gatherings have been collected at 

 this station during the four years. Sixty of these were collected in 1 905, 

 twenty-five in 1906, twenty -four in 1907, and thirty-four in 1908. 

 They are shortly described below. 



1905. 



January. — Eight gatherings were collected in January 1905. Three of 

 these were horizontal and five were vertical hauls. One of the horizontal 

 gatherings was from 15 fathoms and two from near the bottom. The 

 first, which was comparatively small, measured 16 c.c.'s, but the other two 

 were large and measured respectively 250 and 125 c.c.'s. The vertical
