No. 15,698, Mus. Smiths., adult in perfect plumage, mounted ; 

 from the Antarctic Ocean, lat. 64 40' S., long. 103 4' E. from 

 Greenwich, U. S. Expl. Exped., T. R. Peale : type of Ajrtenodytes 

 longicauda, Peale, I. c, and basis of Cassin's article, 1. c. The 

 tail is very long, the central feathers being upwards of 7 inches, 

 though the lateral are only about 2, in consequence of the extreme 

 graduation; all the rectrices are merely narrow linear laminae, like 

 pieces of whalebone with frayed edges. The tibial feathers cover 

 the tarsus in front, but none grow on the tarsus itself, which 

 is very short only about an inch. Middle toe ' and claw 3.00 ; 

 inner do. 2.25, outer do. 2.50 ; nails very long, but blunt ; webs 

 emarginate. The podotheca is entirely reticulate, except a few 

 annular scales at the ends of the toes. The bill is very short, 

 narrow and deep, and densely feathered beyond its middle. The 

 antia3 reach within an inch of the tip, entirely covering the nos- 

 trils ; the broad rounded-depressed and decurved culmen runs in 

 a point on the forehead ; its chord is 1.50 long. The feathers of 

 the antise, and those between the mandibular rami, slope so 

 obliquely and rapidly towards the edges of the bill, that the 

 naked portion of the tomia is only 1.75 inches long, though the 

 whole gape measures 2.50 ; the feathery extension in the inter- 

 ramal space is within .75 of the tip of the mandible. Depth of 

 bill at base over .90. The short nasal groove is very narrow and 

 oblique, running into the tomia behind the hooked portion, and 

 behind widening into a feathered fossa where the nostrils lie. This 

 specimen, as mounted, now stands a trifle over 2 feet high, but 

 measures about 33^ inches (its length in the flesh was 31 inches 

 Peale). The bill is wholly dark colored probably it showed 

 some reddish in life ; the feet appear to have been flesh-colored. 

 The naked edges of the eyelids are 3'ellow. The upper parts are 

 fuscous, only slightly lightened with penguin-blue, of which each
