SLENDER-BILLED FULMAR. 
Procellaria tenuirostris, Aud. 
(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 riypr. 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, parti- 
cularly 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 capture d were 
found to contain a species of sepia and grease.”
