Class II. SHAG. 611 



backward : the whole plumage of the upper part of 

 this bird is of a fine and very mining green, the 

 edges of the feathers a purplilh black ; but the 

 lower part of the back, the head, and neck, 

 wholly green : the belly is dufky : the tail con- 

 fifts of only twelve feathers, of a dufky hue, 

 tinged with green 5 the legs are black, and like thofe 

 of the corvorant. During my voyage among the 

 Hebrides, I faw feveral birds of this fpecies mot : 

 they agreed in all refpedts, but in being deftitute 

 of a creft •, whether they were females, a variety, 

 or diftincSc fpecies, rriuft be left to future natu- 

 ralifts to determine. 



Both thefe kinds agree in their manners, and 

 breed in the fame places: and, what is very ftrange 

 in webbed footed birds, will perch and build in 

 trees : both {mm with their head quite erec~t, and 

 are very difficult to be fhot ; for, like the Grebes , 

 and Divers, as foon as they fee the flam of the gun, 

 pop under water, and never rife but at a confidera- 

 ble diftance. 



We are indebted for this bird to the late Mr. 

 William Morris of Holyhead, with whom we had a 

 conftant correfpondence for feveral years, receiv- 

 ing from that worthy man and intelligent natu- 

 ralift, regular and faithful accounts of the vari- 

 ous animals frequenting that vaft promontory.
