" Much deeper in proportion than the Common Herring, an adult fish eight inches long, being one inch and seven-eighths deep, while a Common Herring of the same depth measures ten inches and a half in length: dorsal and abdominal lines much more convex; the latter keeled, but without serration: under jaw with three or four prominent teeth placed just within the angle formed by the symphysis; the upper maxillae with their edges slightly crenated: eye large: scales smaller than in the other species: no distinct lateral line. Back and sides deep blue, with green reflections, passing into silvery white beneath. Dorsal fin behind the centre of gravity; but not so far behind it as in the Common Herring: number of fin-rays,

Number of vertebrae fifty-four." Yarr.

A new species, obtained by Mr. Yarrell in 1831, from fishermen engaged in taking Sprats at the mouths of the Thames and Medway. Found heavy with roe on the 31st of January: probably does not spawn till the middle of February. Flesh said to be much milder than that of the Common Herring.


From the statements made by Mr. Yarrell in the " Zoological Journal*", it seems probable that there may be yet another species of Herring, larger than either of those described above, occasionally met with in the British seas. Pennant also speaks of one, seen by Mr. Travis, which measured twenty-one inches and a half in length.
