I had long since seen, and have often heard of this deep-sided, 

 larger sort of Madeiran Herring, or " Arenque," from the fishermen, 

 but only recently obtained an opportunity of examining it, and of 

 discovering it to be a new species, nearest to the Pilchard ; but dif- 

 fering chiefly in its greater size, greater depth, approaching that of 

 C. Leachii, Yarr., six, not eight-rayed branchial membrane, and in 

 the production of the last two rays of the anal fin. Like the Pil- 

 chard, it has the dorsal fin in the centre of gravity, and the sub- 

 opercle cut square at the bottom.

 p. 189) at pp. 37 and 38 of my Supplement (Proceed. Zool. Soc. 

 1840 ; Trans, iii. p. 15), and the idea of its distinctness as a species 

 from the common British or Northern Hake, arose from tracing in 

 the form of the dorsal and anal fins in the Madeiran fish, and in 

 Salviani's figure of the Mediterranean Hake, a very appreciable dif- 

 ference from my friend Mr. Yarrell's representation of the British 

 Hake at p. 177 of the second volume of the first edition of his 

 * Fishes.' Having requested his attention to the subject, I learn, 

 however, from the corresponding chapter of his second edition, that
