Calanus, on the other hand, formed only about 25 per cent.; there were 
also a few Temora longicornis and some larval forms. 
Avueust.—Vertical hauls from 10, 15, and 25 fathoms were collected in 
August; all the three gatherings were small. About half of the total 
catch consisted of Calanus and the remainder of Pseudocalanus, U'entro- 
pages hamatus, and Acartia clausi, but a few Hvadne, Podon leuckarti, and 
Parapontella brevicornis were also observed, along with a few larval forms. 
SEPTEMBER.—T'wo vertical hauls, one from 15 and the other from 25 
fathoms, were collected in September. The total catch measured only 
about 1:5 ¢.c.’s. The gatherings were about equal, and consisted almost 
entirely of Calanus, a few Pseudocalanus and Acartia clausi being the 
only other organisms observed. 
OctroBER.—Two gatherings collected in October were also very small. 
They were vertical hauls, one from 15 fathoms and the other from the 
bottom, and consisted almost entirely of Calanus. 
1906. 
Aprit.—— Vertical hauls from 15 and 26 fathoms were collected in April 
1906. ‘They were both small, and together measured only about 4 e.c’s. 
The contents of the first consisted chiefly of Calanus, with a few Pseudo- 
salanus, Centropages hamatus, and a small number of fish ova. In the 
second gathering, Pseudocalanus was.rather more frequent and formed 
about a third of the catch. 
JUNE.—Two gatherings collected in June 1906, comprising a vertical 
haul from 15 fathoms, and one from the bottom (about 25 fathoms), 
measured 3:5 and 4°5 c.c.’s respectively, and consisted almost entirely of 
Calanus. 3 
Avueust.—Two vertical hauls similar to the last were collected in 
August ; one measured 3 and the other 2°5 c.c.’s. In the first Calanus 
formed fully 50 per cent. of the catch, Psewdocalanus 25 per cent., and 
Centropages about 20 per cent. A few specimens of Parapontella brevt- 
cornis and Thaumaleus rigidus were observed in this haul. In the bottom 
gathering Calanus, Pseudocalanus, and Centropages were about equally 
numerous. Acartia clausi was also observed, but only in small numbers. 
SEPTEMBER.—The two vertical hauls collected in September were very 
small, and together measured only about 2 .c.’s. They consisted for the 
most part of Calanus and Pseudocalanus in nearly equal numbers. A 
few Centropages hamatys were also present in the bottom gathering. 
OctoBER.—Vertical hauls from 15 and 25 fathoms were also collected 
in October ; they were both small gatherings. In the first Calanus and 
Acartia claust were about equally numerous, but a few specimens of 
Anomalocera and Decapod larvee were also noticed. The second consisted 
for the most part of Calanus, Pseudocalanus, and Acartia clausi, together 
with a few Centropages hamatus. There were also a small number of 
Sagitta and Decapod larve present in this gathering. 
1907. 
Aprit.—Two vertical hauls, one from 15 and the other from 29 fathoms, 
were collected in April 1907. Both gatherings were very small, and 
consisted chiefly of Calanus, mixed up with which were a few other 
common forms. 
May.—The two vertical hauls collected in May, the one from 15 and 
the other from 27 fathoms, showed a marked difference from the previous 
gatherings in the larger amount of pelagic crustacea captured. But the 
two samples, which measured respectively 11 and 13 c.c.’s, consisted almost 
entirely of Calanus, no other species being noticed.
