A portion of this sample was measured in detail with a view 

 to indicating racial character. As was shown m the report (New 

 Series, 111) for 1913-14, the measurements resolved themselves 

 into straight hues when expressed with relation to length. In 

 the original table in that report the various measurements were 

 referred to the length of the scale covered portion of the body, 

 but as the total length has been adopted for other fishes and is 

 more generally employed the ojDportunity has been taken in Table 

 V. to express the measurements made in 1913 in terms of total 

 length, together with the sample from the Firth of Forth obtained 

 this year (1917). It will be at once clear that the sample differs 

 from both the trawl and the drift net herring of the Northumber- 

 land coast Avith reference to the position of the pelvic, ventral 

 (anal) and the dorsal fins. It is also plain that the suggestion 

 that the sample of 1914 got so far out early in the season of that 

 year belonged to the Firth of Forth school was ^\Tong. The sample 

 proved (Report, New Series, IV.) to include herrings of two to nine 

 winter rings, wdth four to five winter rings predominating, and 

 evidently belonged to one of the summer spawners.
