366 PISCES (OSSEI) ACANTHOPT. [CARANX. 



Mr. Couch states* that "two of this species a few years since 

 accompanied a ship from the Mediterranean into Falmouth, and were 

 taken in a net." It has been observed in the British seas, under similar 

 circumstances, in a few other instances. Is well known for its habit of 

 following vessels to a considerable distance, in order to get what falls 

 from them.

Mr. Couch states that he believes the Albacore to be not uncommon in 

 the Summer off Cornwall, though keeping at a distance from the shore, and 

 but rarely taken. This name, however, having, like that of Bonito, been 

 applied to more than one species, it does not appear with certainty to 

 which he alludes. If he .refer to the Sco7nber glaueus of Linnaeus, this last 

 is synonymous with the Lichia glaucus of Cuvier and Valenciennes. I 

 have accordingly annexed a corresponding reference to their work for 

 a description and figure.

LENGTH. From twelve to sixteen inches. 



DESCRIPT. (Form.) General form resembling that of the Mackarel : 

 tail slender; head a little pointed, rather less than one-fourth of the 

 entire length: greatest depth a little more than one-fifth; thickness 

 half the depth: lower jaw projecting beyond the upper, inclining up- 

 wards at an angle of forty-five degrees : in each jaw one very narrow 

 row of extremely minute teeth, more sensible to the touch than to 

 the eye ; the same on the vomer and palatines : eyes large, above the 

 middle of the cheek : cranium, cheeks, and all the body, covered with 

 small scales ; snout, jaws, and opercular pieces, without scales, the 

 upper half of the opercle excepted: lateral line parallel to the back, 

 at one-fourth of the depth, till opposite the commencement of the 

 second dorsal; then bending obliquely downwards and backwards; 

 when in a line with the ninth ray of that fin, passing off straight to 

 the caudal at half the depth ; protected throughout its course by a series 

 of large scaly laminse, seventy-two in number, three or four times as 

 high as broad, closely compacted ; the last forty of these laminae with 

 keels terminating backwards in sharp points, the keels more elevated 

 and the points sharper as they get nearer the caudal : first dorsal com- 

 mencing at about one-third of the length, triangular, its length and 

 height about equal; third and fourth rays longest; before it a small, 

 but sharp, horizontal spine, with the point directed forwards : second 

 dorsal immediately behind the first ; three times its length ; its height 

 at first nearly the same, but afterwards falling, and remaining low 

 throughout the rest of its length: behind the vent, two stout, sharp 

 spines, united at their base by a short membrane; then the true anal, 

 exactly similar to the second dorsal excepting in being shorter, and com-
