AVES PHALACROCORACID^C. 5 1 9 



secondaries and tcrtials on their exposed surface uniform dull, glossy 

 bottle-green ; an alar bar of pure white extending from the base of the 

 forearm well toward the wrist; this varies from three to four inches in 

 length ami U half to three quarters of an inch wide; under wing-coverts 

 and axillaries dull blackish, with more or less glossing of green. 



Lower parts : The flanks, thighs and under tail-coverts black, with a 

 steel-blue gloss ; the rest of the under parts pure white with a fine silky 

 sheen. 



Bill : Yellow, with strong shading of horn brown ; the nasal caruncles, 

 which are not prominent, yellowish green shading into bright blue on the 

 naked skin about the eye. 



Iris]: Bright green in the breeding season ; yellow grey to hazel brown 

 at other times. 



Feet: "Tarsi scarlet" (Darwin). 



An immature female so far as plumage goes, but probably a bird which 

 had passed one breeding season, is among the birds collected by Mr. 

 Hatcher. It is catalogued 7912 in the University Museum and was taken 

 on the coast near Mount Tigre, Southern Patagonia, August i8th, 1896. 

 I am unable to refer this to young birds of the year. It has the upper parts 

 ashy brown, the tips of many feathers being whitish, there is a decided 

 and well grown crest, the white region on the head extends well forward, 

 nearly to the eye, and passes above, wholly surrounding the ear; the alar 

 bars are present but not well defined ; there is no dorsal white patch ; the 

 under parts are pure white, as in adults, save that the thighs and under 

 tail-coverts are black or brownish black ; there are no carunculations about 

 the face and the feathers reach unbroken to the upper point of the culmen 

 and even the usual bare skin in front of the eyes is slightly feathered ; the 

 dry bill looks as if it had been dull brown in life, but the feet must have 

 been, from their appearance, bright yellow. 



Presumably immature birds are like the closely allied young of Phala- 

 crocorax albiventer. 



M. J. Nicoll (Ibis, Jan., 1904, p. 48), describes the colors of the eyes, 

 etc., as follows : " Iris green ; eyelids blue ; face and nasal caruncles yel- 

 lowish green. 



Geographical Range. South Patagonia on the Atlantic coast at least as 

 far north as the mouth of the Rio Santa Cruz ; the Straits of Magellan and 

 Fuegian waters ; South Georgia ? Pacific Coast of South America as far 

 north as Chiloe Island.
