to tip of bill 2.50. While a much smaller bird than patachonica 

 (Forsteri), it is thus seen that the wings, tail, and feet are rela- 

 tively longer, and that the bill, besides being relatively longer, 

 is actually made of equal length, if not absolutely longer, in con- 

 sequence of the less extent to which the feathers of the front 

 encroach upon the upper mandible, the antioe falling short of half 

 the distance between angle of the mouth and tip of the bill. 

 Another and yet stronger character is, that the sides of the under 

 mandible are entirely naked, whereas in patachonica (Forst.) the 

 feathers encroach so much that hindwards only the tomial edge of 

 the mandible remains bare. This difference heightens the seeming 

 greater size of the bill of pennantii ; it likewise makes the brightly 

 colored area larger, and gives it a different shape. The tarsi of 

 pennantii are entirely naked, and not even hidden hy the tibial 

 plumes ; whereas in patachonica (F.) the tarsi are largely ptilose, 

 and wholly hidden by feathers, as are also the bases of the toes. 

 The general pictura of the plumage is the same ; but the neck 

 shows a very noticeable difference, the gnlar black running far 

 down in a sharp point embraced betwixt the forks of the narrow 

 median anterior jugular line of \ r ellow that after bifurcating 

 mounts on either side of the neck and head, there to form a large 

 very yellow spot, bounded immediately by the dark color of the 

 neighboring parts ; and moreover, the isolated black line running 

 up in the whitish of the side of the neck from the shoulder 

 towards the throat, as observed in the Smithsonian specimen of 

 patagonica, is not seen here. 



I am not satisfied, however, that these precise points of color- 

 ation are sufficiently distinctive of the species as compared with 

 its congener. It is probable that the only reliable characters are 

 to be found in the larger size, proportionally shorter members, 

 much more extensively feathered bill, and feathered tarsi, of 

 patagonica ; and all these points seem to be accounted for by a 

 difference in habitat, patagonica being more decidedly antarctic 

 than longirostris.
