It will be observed from this Table that the distribution of Acartia 
varies to a greater extent from that of Calanus 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 Jemora, and more similar to 
that observed in Calanus. It is also noticeable that Acartie 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
