belonging to the adult female No. 7807, described. The down is marked 

 off into color areas on the body much as in the adult. The upper parts 

 are dusky or blackish, with sandy and rufous brown fringing to the down 

 feathers. The sides and flanks are much like the back, but the fringing 

 to the feathers is greyer. The region about the vent 

 is similar to the sides. The abdomen, breast and 

 chest are white shading into the color of the sides 

 and flanks. 



The neck and head are striped longitudinally with, 

 rufus, blackish and white stripes, except on the back 

 of the neck which is dull black, much like the back, 

 and with some faint sandy brown fringing to the 

 down feathers.

This grebe is apparently a permanent resident even as far south as 

 Sandy Point, for Dr. Cunningham speaks of it as follows under head of 

 June 8th, the mid-winter of Patagonia: "A specimen of a curious little 

 grebe (Podiceps rollandi}, very common in the Strait, but difficult to 

 shoot on account of its activity in diving, was in addition procured, be- 

 ing found by one of the officers frozen into the ice of a small stream." 

 (Nat. Hist. Strs. Mag., p. 222, 1871.) The party were ashore at Sandy 

 Point o'n this day, and the bird referred to as Podiceps rollandi was 

 Podicipes americanus, P. rollandi, so far as known, being restricted to the 

 Falkland Islands.
