 and islands of the North Atlantic ; breeding from the Gulf of St. Law-

6. Briinnich's Murre (31. tfria Idmvia). — 

 A bird similar to the last, but with a 

 smaller and shorter bill and a slightly 

 onger wing. In breeding plumage 

 there is some difference of color, 

 but in winter, when found in the 

 waters off our eastern shores, 

 the difference in length 

 of bill is the distin- 

 guishing mark. (Thick- 

 billed Murre.)

7. Razor-billed Auk (32. Alca tdrcla). — A short, high, thin- 

 billed auk, with the upper parts generally sooty-black, and the 

 lower parts white. The 

 black bill is crossed by a 

 white band, there is a white 

 line from the bill to the 

 eye, and a line is formed 

 on the wings by the white 

 tips of the secondaries. The 

 bill is flattened sidewise, 

 whence the bird derives the 

 name of razor-bill. It has 

 the habit when on the water of turning its tail almost directly 

 upward. (Tinker.)
