. The birds of Iona & Mull. Birds. LETTER XXI. 155 feature, and add very much to the quaint appearance of this queer species of water-fowl. The iris is a rich ruby red, with an extremely fine exterior thread of white running round it. I have compared these specimens with a similar one shot in Canada, where it is abundant on the large lakes and rivers. It there rejoices in the descriptive and euphonious title of " Hell-diver." The most remarkable difference is that in the American specimen the horns are connected by a band of the same bright orange buff running across the forehead

The most remarkable difference is that in the American specimen the horns are connected by a band of the same bright orange buff running across the forehead at the base of the bill. This makes a very characteristic difference in the personal appearance of the two birds, which otherwise seem identical, and seems to be so considered by Wilson, who simply calls it Colymbus, or Podiceps Cornutus, as we do our Horned Grebe on this side of the Atlantic. So much for the notes of the season, as noted on the banks of the Gilp, which, you see, is a very inferior post of observation to Columba's old isle. m. -'•V 11^ 1 **.
