Crab Zoeas were present in very small quantities in 

 1914, in most months the numbers recorded heing only 

 two or three in a haul. The largest haul, and, in fact, 

 the only one which runs to three figures, is 320 on 

 April 24 th. 



A considerable haul of the " Mysis " -stage of 

 Crangon, amounting to about 560 individuals, was 

 obtained on April 8th, at a mile off Spanish Head, with a 

 net weighted so as to tow at about 5 fathoms. Crangon 

 larvae, although frequently present, usually occur in much 

 smaller numbers per haul. 



The Nauplii of Balanus ranged in 1914 from January 

 to May inclusive, and during these months the average 

 haul and the greatest single haul were as follows : —

After this large haul early in May the numbers fell 

 off rapidly, and not a single Nauplius was captured in 

 June. In the previous year the range was from the end 

 of January to late in June, and the largest haul was over 

 450,000 on March 26th, a good deal larger than anything 

 obtained in 1914. 



The Cypris stages made their appearance (two 

 individuals) on April 20th, and increased slowly up to 

 1,920 on May 21st, and then, after a haul of 61 on 

 June 1st, rapidly disappeared, the last captured being a 

 single specimen on June 25th. The great reduction in
