June. — Five hauls were collected in Jvine at the usual depths ; they 

 showed that pelagic Crustacea were still fairly common, but scarcely so 

 plentiful as in the previous month. The gatherings measured respectively 

 5*5, 9-5, 11-5, 14-5, and 15*5 c.c.'s, and indicated a fairly uniform distribu- 

 tion of the organisms mentioned. 



August. — The gatherings (four in number) collected in August, com- 

 pared with those for May and June, showed a large falling off in the 

 numbers of pelagic Crustacea all through the water, the quantity of each 

 of the four hauls being respectively 2-5, 2, 3'5, and 6*5 c.c.'s. 



Decembek. — The gatherings collected in December compi-ised vertical 

 hauls from 15, 30, 45, 60, and 70 fathoms, and their contents measured 

 respectively 5, 11, 47, 63, and 40 c.c.'s. They show a considerable increase 

 over the August gatherings. In these gatherings Gcdanus was the only 

 species observed. 



Station III., Upper Loch Fyne (fully 1 Mile S.E. from North 



Kames). 



The number of gatherings collected at this station was sixty-eight. Of 

 these, thirty-one were collected in 1905, ten in 1906, eleven in 1907, and 

 sixteen in 1908, and are briefly described below. 



1905. 



January. — Two gatherings collected in January — one from 15 fathoms 

 and one from the bottom — were very small ; that from the bottom measured 

 only 2"5 c.c.'s, the contents consisting entirely of Calanus. 



March. — The gatherings collected in March comprised three horizontal 

 and three vertical hauls. The horizontal gatherings were collected at the 

 surface, mid-water, and bottom, and measured respectively 2, 4'5, and '75 

 c.c.'s. Two of the vertical hauls were from the bottom and the other from 

 15 fathoms; they were small gatherings, and consisted for the most part 

 of Calanus; but a few other forms also occurred, including Acartia clausi, 

 Diaixis pygmoeus, Decapod larvae, and fish ova. The horizontal consisted 

 chiefly of Calanus, with a few Fseicdocalanus, Centropages hamatus, 

 Acartia clausi, Evadne nordmanni, larval and young Crustacea, and Sagitta. 



April. — Six gatherings collected in April comprised three horizontal 

 and three vertical hauls. The horizontal hauls were from the surface, 

 mid-water, and bottom, and measured about 3, 1'5, and 16"5 c.c.'s respec- 

 tively. One of the vertical hauls was from 15 fathoms and the other two 

 from the bottom (28 to 30 fathoms). The first measured 2'5 c.c.'s, and the 

 other two together about 8"5 c.c.'s (3 '5 and 5 c.c.'s). Though Calanus was 

 the most common species, Centropages hamatus was also frequent, so also 

 was Pseudoca^anus. In one of the bottom gatherings, for every 100 

 Calanus there were about 35 Centropages and 15 Pseudocalanus, a few 

 Acartia clausi, Euchceta, Evadne nordmanni. Decapod larvse and Sagitta 

 and a few fish ova. 



May. — The gatherings collected in May comprised one surface and 

 three veitical hauls. They were small gatherings ; the total catch measured 

 scarcely 4 c.c.'s, of which Pseudocalanus formed about 4 per cent., Centro- 

 pages 10 per cent., and Calanus only about 8 per cent. Temora longi- 

 cornis, Acartia clausi, and Podon leuckarti were also sparingly represented. 

 Oikopleura was frequent in the surface gathering, but not in the others. 



June. — Two gatherings collected in June included a surface haul and a 

 vertical haul from the bottom. They were both small and measured about 

 1*5 c.c.'s each. Centropages and Pseudocalanus were about equally 

 numerous, and together formed about 7U per cent, of the entire catch.
