a-c. Skins, from 8 to 10 inches long. From Mr. Yarrell's Collection, 



Mr, Yarrell's Collection was entirely composed of specimens of 

 British, and of a few Mediterranean species. The locality has been 

 noted by him only in a small proportion of the specimens, and un- 

 fortunately no record has been preserved by him as to the histoiy 

 of the specimens of this species. Nearly all the Mediterranean spe- 

 cimens are prepared in a uniformly peculiar manner, difterent from 

 that in which the British specimens in general and the three speci- 

 mens of A. lopliotes especially were preserved. It is not at all im- 

 probable that those three specimens really are British.

The height of the body is rather less than one-third of the total

 the caudal nearly one-sixth. The greatest depth between the anal 

 fin and the straight portion of the lateral line is much less than the 

 length of the head. Scales deciduous, smooth, obscurely ciliated ; 

 interorbital ridge very narrow. Lateral line with a curve above the 

 pectoral, the depth of the curve being equal to the width of the base 

 of the pectoral. Snout rather longer than the eye, the diameter of
