during the year. The arrangement is the same as that adopted 

 in the XXI Annual Keport published in 1913. 



Clupea sprattus, Linn. — Sprat. 



The eggs were found in the plankton collected in Carnarvon 

 Bay and along the North Wales Coast from the middle of May 

 to the end of the month. They occurred in Cardigan and Red 

 Wharf Bays in the beginning of June, and off Nelson Buoy in 

 the middle of June. No sprat eggs were found in any of the 

 July collections. One sprat egg was found in a sample of 

 plankton taken in Carnarvon Bay on August 14th. So far as 

 numbers show, the maximum spawning period of the sprat 

 occurred about the end of May. A sample collected six miles 

 N. of Great Orme's Head on May 29th contained seventy-two 

 eggs. Another sample taken in Red Wharf Bay on the same 

 date had twenty-seven. A collection from near the Causeway 

 Buoy, in Cardigan Bay, on June 4th contained thirty-five sprat 

 eggs. The numbers diminished rapidly after these dates, and 

 the eggs ceased to be represented in the plankton taken after 

 August 14th. 



Gadus callarias, Linn. — Cod. 



The first eggs of the cod were found in plankton collected 

 five miles E. of Point Lynus on February 6th. They were 

 present in thirty-three samples taken in various parts of the 

 Irish Sea from Bahama Bank to off Point Lynus, between the 

 date given and May 9th. The numbers present in the samples 

 gradually increased until the period between March 18th and 

 April 15th when the maximum was apparently reached. 

 After the latter date they diminished, and finally disappeared 

 from the plankton in the second week of May. Plankton 

 samples collected half way between the " Hole " and Bahama 

 Bank on March 18th ; eight miles E. J S. of Point Lynus on 

 April 3rd ; twenty miles W.N.W. from Piel Gas Buoy on April
