312 Part I11.—Twenty-fourth Annual Report 
The Table embodying the references to the collections of the Garland 
and the above measurements shows generally the same features. 
One sees the various groups, the spring series and the autumn series, 
as well as the older ones(B). At A, there is no doubt about the clupeoids 
representing the herring, but later, as at C, the sprat is doubtless present, 
and the smaller fishes represented in July may also be sprats. 
In the Tables and curves appended to this paper (Tables I.-III., Plates 
XVII.—XTX.) it will be seen that the groups of herrings are well 
separated from one another, comparatively little admixture of the spring 
and autumn herrings taking place—though it does occur—and the eluci- 
dation of the rate of erowth of the herring would be an extremely simple 
matter if it were not for the existence of these two series, one derived 
from spring and the other from autumn. 
In dealing with the post-larval herrings, I have had the advantage of Dr. 
Williamson’s experience in their diagnosis, and I have to thank him for his 
assistance in this respect and for measuring a number of these collections.
