SLENDER-BILLED FULMAR. 



4- Procellaria tenuirostris, Jlud. 



(not FIGURED.) 



This species agrees in general with the last described; but its bill is much 

 more elongated, comparatively slender, and with the nasal case, half of the 

 unguis of the upper mandible, and the tip of the lower, black. The outline 

 of the nasal case is a little concave, and its ridge is somewhat carinate. 

 Whether this individual be of another species, or of the same, having an 

 accidentally elongated bill, cannot perhaps be determined without a series of 

 specimens; but it is probably a true species, as neither of the other two have 

 the bill black in any part or at any period. Supposing it to be distinct, I 

 have named it the Slender-billed Fulmar, Procellaria tenuirostris. 



The following note from Mr. Townsend was appended to this specimen: 

 — "Within a day's sail from the mouth of the Columbia river. Its habits 

 are very similar to those of Procellaria capensis, keeping constantly around 

 the vessel, and frequently alighting in her wake for the purpose of feeding. 

 They are easily taken with a hook baited with pork, and at times, particu- 

 larly during a gale, they are so tame as almost to allow themselves to be 

 taken with the hand. The stomachs of most of those that I captured were 

 found to contain a species of sepia and grease."
