within a few miles of the island, and have no doubt that it 

 breeds there. 



Alca torda (Linn.), Eazorbill. — Plentiful on both islands. 

 On Sula Sgeir it breeds under the stones on the level surface 

 of the island, while on Eona it lays its single egg in some 

 hole or cranny near the top of the cliff. 



Zomvia troile (Linn.), Guillemot, — Plentiful on both islands. 

 On Sula Sgeir I was surprised to find it breeding on the 

 level top of the island among the puffins and razorbills. 



Zomvia troile, var. ringvia, Bridled Guillemot. — I noticed 

 a good many birds of this variety on Sula Sgeir, where I 

 was fortunate enough to take several eggs from under the 

 birds. 



Uria grylle (Linn.), Black Guillemot. — There were a good 

 many of these birds about the west end of Eona, where I 

 took one egg. I did not see any on Sula Sgeir. 



Fratercula arctica (Linn.), Pufi&n. — This species simply 

 swarmed upon both islands. On Sula Sgeir they were to be 

 found under the stones, and on Eona all round the island 

 wherever they could burrow. A considerable number of the 

 young are annually taken for the purpose of being salted for 

 food in the same manner as those of the gannets. This is, 

 however, done at an earlier period — viz., about the end of 

 July, at the same time as the sheep-shearing takes place on 

 Eona. From 500 to 1000 are thus captured; they are either 

 extracted from their nests by means of a hook tied to the 

 end of a stick about 2 feet long, or, if they have left the nest 

 a noose attached to the extremity of a long rod is slipped 

 over their head as they sit on the rocks.

 Descrijytion of a Nevj Species. By Dr E. H. Traquair,

(Read 20tli February 1884.) 



There can be no doubt that the name Megalichthys was 

 originally suggested to Agassiz by the gigantic teeth of the 

 great round-scaled fish first brought into notice by the re-
