254 OSTEOLOGY OF TUBINARES AND STEGANOPODES. 



Alaska. They have been of the greatest service to me. This bird 

 ranges over the Pacific Ocean at large. 



Rodgers' Fulmar ( F. glacialis rodgersii), the skeleton of which we will 

 examine, is confiued to the North Pacific. This is likewise the habitat 

 of the Fork-tailed Petrel (0. furcata), four nearly perfect skeletons of 

 which bird arc found in our list for examination.

The skull of the doubtful species of Albatross, No. 1G738, fiom Oona- 

 laska, differs from those in my possession of I), albatrus, and probably 

 is some other species, perhaps D. nigripes or Phcebetria fuliginosa. 



The sternum of an Albatross bought by Mr. Jouy in the Tokio mar- 

 ket appears to agree very well with specimens of the sternum of the 

 Short- tailed Albatross. 



Skeleton of Oceanodroma furcata (Fork-tailed Petrel.) 



(Fig. 1.) 



We find in the skull of this Petrel some very excellent characters, a 

 number of which it holds in common with the Fulmars, and still fewer 

 with the Albatrosses. 



Regarding it from a lateral view, we observe the superior mandible 

 to be powerfully hooked, with the culmen, transversely, very narrow 

 between the longitudinally elliptical osseous nares. 



The nasal assumes the holorhinal type, and a concavity appears 

 above, over tin; region of the craniofacial junction. 



A lacrymal is a very peculiar bone in this bird, it, with a projecting 

 part of the frontal at the superior externo- anterior angle of the orbit, 

 havingquite an extensive face that looks directly backward, thus forming 

 a good share of the anterior wall of the orbital cavity. From this portion 

 two processes are sent out; the one reaches directly forward to articu- 

 late h\ its extremity with the hinder tree margin of the corresponding 

 nasal. This prpcess forms a wall for the upper part of the rhiual chain
