East Coast. -Wick, 30 miles E. by N. of, 28th June 1906 :— 5 Imm. 

 dev., 22 to 24 cm. : eggs, *3 mm. : o, 6 mm. : t, 3, 5 mm. : fat, large

 fied, 21 to 24 cm. : t, 6 mm. : fat, large quantity. Some stomachs were 

 empty ; others contained copepods. These herrings were fat, but not so fat 

 as the Castlebay herrings. As to the exact description of the " Spents," it 

 is difficult to decide to what spawning they belong. They were to all 

 appearance spent fishes, that is, so far as the reproductive organs went ; but 

 all, even those with eggs as small as "2 mm., had a large quantity of 

 abdominal fat. One of these having eggs '2 mm. I had described as " ap- 

 parently just spent." It is no doubt a winter spent, or may be a spring 

 spent, while those having larger eggs might be autumn or early winter 

 spents. One of the S. Spr., a male, was a full herring.
