The HE is much cotifusion in the two or three writers I 

 have been able to con.sult on the fish to which I have as.?igned 

 the English name a.s above; and there cannot be a doubt 

 that the name Bhombiis carditia given to it by the Swedish 

 authors, in their work on Scandinavian fishes is misapplied, as 

 it hears little likeness to the species which is thus named by 

 Cuvier, who refers to Jago's figure in Ray's Synopsis, f. 2, 

 where it is repiesentcd under the name ot Whiff. This last 

 named fish, Rhovihus cardina of Cuvier, is the Carter of our 

 work. But on the other hand, Ekstrom's Topknot so nearly 

 resembles the species of Topknots Ave have already described, 

 that 1 have no doubt it has been hitherto confounded with 

 them, although when seen together the difference is easily 

 discerned. 



The example from which our figure and description have 

 been taken, is the first that has been recognised in Britain; 

 and it was caught in the Bristol Channel early in the year 

 1863, from whence it came into the possession of Edmund T. 

 Higgins, Esq., to whom I am indebted for the opportunity of 

 making it known to natuialists. 



Its habits appear to be little known even to the Swedish 

 authors, Fries, Ekstrom, and Nilsson, who mention it; but 

 there is reason to believe that its resort is lt;ss in rocky 

 ground than the two other kinds of Topknots. Compared 

 with them the proportion is not nearly so wide in comparison 

 with the length, 'ind it is also much thinner; gape wide; 

 angle of the mouth depressed; lower jaw a little protruding, 

 with a small chin. Eyes near each other, separated by a thin
