It will be observed from this Table that the distribution of Acartia 

 varies to a greater extent from that of Calanvs than that of Temora was 

 found to do. The greatest number of yearly records of Acartia shown in 

 the Table is that for 1891, and not only is the yearly total number for the six 

 stations for 1891 the greatest, but the same thing is observed in the total 

 number of each of the stations for that year. If, on the other hand, a com- 

 parison be made between the highest and lowest total numbers for the six 

 stations, the difference is rather less than in Temora, and more similar to 

 that observed in Calanus. It is also noticeable thsit A cartice are compara- 

 tively usually more frequent during the summer months. It will be 

 observed, for example, that the highest of the total monthly records for
