108 NEWTON ON BIRDS IN GREENLAND. 



shade of colouring. The young are supposed to be darkest in 

 hue, but some seem to keep this sign of immaturity all their 

 life, 



41. PuFFiNUS MAJOR. Greater Shearwater. " Kakordlungnak." 

 Marked by Prof. Reinhardt as breeding in Greenland, and said 



by Holboll to be found in great numbers from the southern point 

 of the country to lat. 65° 30' N. ; the eggs of this bird are utterly 

 unknown. Shearwaters of some species have many times been 

 noticed in abundance off Cape Farewell. 



(47.) Pifjfimcs JmJili. Grey Shearwater. 



Only known from Greenland by a specimen received thence 

 by Herr Moschler and now in the Ley den Museum (Schlegel, 

 Mus. Pays-Bas, Procellarice^ p. 24). 



(46\) Puffinus anglorum. Manks Shearwater. 



Once received from Greenland. The changes of plumage 

 undergone by Shearwaters seem to be somewhat analogous 

 to those of the Skuas, and no ornithologist at present has 

 been able to give a rational explanation of them. 



42. TiiALASSiDROMA LEACHi. Fork-tailcd Petrel. 



Constantly observed near the coast to lat. 64° or Q5° N., and 

 most frequently about the entrance of Godthaab Fjord, on the 

 islands in which it is said to breed.* 



(4p.) Thalassidroma buhveri. Bulwer's Petrel. 



Only known from Greenland by a specimen received 

 thence at the Museum of Leyden (Schlegel, Mus. Pays-Bas, 

 ProceUaricc, p. 9), from the Moravian missionaries. 



43. rratercula arctica(?) Puffin. '' Killangak." 



Puffins seem to be nowhere common in Greenland, and are said 

 by HolboU not to breed further south than lat. 63° 30' N., which 

 seems a questionable assertion. Whether two species are found 

 there is also a doubtful matter. f The Puffin of Spitsbergen 

 appears to the compiler to be justifiably separable from that 

 which inhabits more southern stations in Europe on account of 

 its much larger size, and to it should probably be assigned the 

 name of F. glacialis (Leach), but the type of that supposed 

 species is said to have been received from Greenland, whence 

 Cassin also says he has seen it. On the other hand Prof. Rein- 

 hardt says that all the Puffins he has examined from Greenland 

 belong to the common species F. arctica. The difference between 

 the two is admitteilly only one of size, though that difference is 



* T-\vo examples of Procellaria pelagica, the common Stormy Petrel, with 

 the locality " Groeuland " are contained in the Museum of Leyden, having been 

 received direct from Holboll, who doubtless obtained them on one of his voyages, 

 but whether in the Greenland seas is another matter. 



f Fratcrcida cirrhata, the Tufted Puffin, a bird of the north-west coast of 

 North America, is said to have been received from Greenland (JNIuschler, 

 .Journ. f. Orn. 1856, p. 335,1 ; but there is most likely some mistake about it.
