556 Capt. Sabink's Memoir on the Birds of Greenland, ^'C. 



the neck ; the black of the back of the neck extends down the 

 back, but in the centre of the upjDcr part of the back near the 

 neck is a patch of black feathers edged with ferruginous ; the 

 scapulars are long and narrow, black in the centre and edged 

 with ferruginous-white, the longer ones having more white ; 

 the wings are a brownish-black, the quill feathers being the 

 palest ; the lower belly and sides to the rump and the under tail- 

 coverts are white, a line of black descending between the while 

 from the back to the tail ; of the four middle tail-feathers two 

 are eight inches, the otliers are about four and a half inches long. 

 Briinnich gives this bird in five different states of sex and plu- 

 mage, the second (No. 76) is the male in summer plumage. Mon- 

 tagu, in the Appendix to his Supplement, has described the trachea 

 well ; the figures in the annexed engraving, Tab. XXX. fig. 3 and 4, 

 will convey a very correct idea of its appearance : it is most curi- 

 ous and singular in its construction ; the window-like formation 

 at the lower part next the tympanum is particularly so. 



Subjoined is a complete list of the birds of Greenland, as far as 

 I conceive they are at present ascertained ; the Fauna Groenlan- 

 dica has been taken as the foundation thereof, and the alterations 

 which appear to be necessary have been made in it. 



The species enumerated by Fabricius are fifty-four: I have re- 

 duced five of these, considering them as synonyms of some of the 

 others, bat have enlarged the list again by the addition of an equal 

 number of sptxies which had not fallen under the notice of that 

 author ; the names of the five reduced species are placed in italics 

 under those to which I have referred them; and the added spe- 

 cies are marked with an -]■ ; in those cases where I have given the 

 bird of the Fauna Grocnlandica under a more correct name, the 

 synonym of that work follows in the same line in italics. The birds 

 which are marked * are described in the preceding pages.
