In 1889 small Coelenterates were abundant in a bottom tow-net gather- 

 ing collected at Station IV. in July. In 1890 they were abundant in a 

 surface tow-net gathering at the same station in May. In 1891 they were 

 abundant in a bottom tow-net gathering collected at Station I. in July, 

 and at Station IX. in June ; and they were also abundant in a surface 

 tow-net gathering at Station IX. in October. Coelenterates were 

 frequently obtained in 1892, but in none of the records for the selected 

 stations are they described as abundant. In 1893 they were abundant in 

 a bottom tow-net gathering at Station I. in August, and also at Station 

 IV. in the same month, but at the latter station they were abundant in 

 the surface as well as in the bottom tow-net ; in the same year they w r ere 

 also abundant in a surface tow-net gathering at Station V. in May. In 

 1894 Ccelenterata were abundant in bottom tow-net gatherings collected 

 in June at Stations III. and IV., while in August 1895 they were 

 abundant in a surface gathering at Station III., and in a bottom gather- 

 ing at Station IV. 



From an examination of the annexed Table showing the general distri- 

 bution of Ctenophora and Hydromedusae, it will be observed that there is 

 a somewhat curious contrast between their distribution and that of 

 Sagitta. On comparing the total number of the records of Ccelenterata 

 and Sagitta for each of the three inner and outer stations, it is found that 

 while in the case of Sagitta the larger numbers are those of the outer 

 stations, it is just the reverse with the Coelenterates, the largest numbers 

 being those of the inner stations. This contrast is better seen by arrang- 

 ing the numbers of the records of Sagitta and Ctenophora for each of the 

 stations, in juxtaposition as a formula, thus : — 



Formula (1) shows the total number of records of Ccelenterata for 

 all the six stations, to which the numbers of the records of Sagitta are 

 added for comparison : — 



Inner Stations. Outer Stations.

It would thus appear that while Sagitta was comparatively scarce at
