rare of twice that size. The colour is green, more or less brilliant; large and well-coloured individuals may be confounded with the Green Wrasse (Labrus Donovani), which is also not rare with us; but the little Corkwing may be distinguished by having the fore gill-plate minutely toothed along its free edge, and by a black spot on each side of the tail, just before the commencement of the tail-fin.

It attains six or seven inches in length. To both species Ovid's descriptive line will apply:—
"Tum viridis squamis, parvo Saxatilis ore:"
