There is one aspect of the question of the distribution of these young 

 Crustaceans, as well as of that of the various other invertebrates touched 

 upon in this paper, that it is well to keep in view in an inquiry of this 

 kind. I refer to the individual frequency or abundance of these organ- 

 isms at one time, or at different times, apart from the frequency or rarity 

 of their recorded occurrences. In the Table showing the distribution of 

 the young Crustacea the maximum numbers of the yearly records are, speak- 

 ing generally, those for 1891, 1892, and 1893 ; while, on the other hand, 

 if the individual frequency of the creatures be taken into account, the 

 results brought out will be somewhat different. For example, young 

 Crustacea are described as abundant in four of the records for 1890
