numbers in passing from the Nauplius to the Cypris 

 stages is always interesting. 



Gastropod larvae were again present in considerable 

 quantity in every month of the year. The largest 

 individual hauls were on February 26th (5,200), October 

 28th (5,800), and November 9th (13,800). In the previous 

 year the largest hauls were in March and November. It 

 looks as if there were two different sets of Gastropods, 

 the one reproducing in early spring, and the other in 

 late autumn. These larvae obviously require closer study 

 and identification. 



Lamellibranch larvae were also present in quantity 

 throughout the year, and were more abundant than the 

 Gastropods in every month. The highest records were 

 on February 26th (8,800), May 12th (6,050), September 

 15th (15,200), October 31st (16,000), November 9th 

 (13,000), and December 9th (15,800). These numbers, 

 though not quite so high, correspond fairly well with 

 those for 1913. 



Medusae and Ctenophora. 



Although Medusae were present in small numbers 

 throughout the year, they only reached a hundred or over 

 per haul in April, May, June, and October (500, the 

 maximum, on October 9th). The numbers are a good 

 deal smaller than those present in June, July, and 

 September of 1913. 



Ctenophora do not seem to have ever been present 

 in any quantity in 1914. Nothing corresponding to the 

 \;i>1 swarms of Pleurobrachia which we have occasionally 

 met with in the past occurred during this year. 



Fish Eggs. 



Mr. Andrew Scot I lias deal! with the fish eggs in 

 more detail in a separate article' in this report, so we
