SLENDER-BILLED FULMAR. 333 



The young bird is of a uniform dull light dusky-grey colour ; a 

 patch before the eye and the primary quills dusky. Its bill and feet 

 are also yellow ; the former as in the adult ; the outline of its nasal 

 case straight, its ridge carinate. 



Length to end of tail 19^ inches ; bill along the ridge l^^, nasal 

 case II ; wing from flexure 12i''2 5 tail 4:^%. 



The tail-feathers of Procellaria glacialis are erroneously stated, at 

 p. 450 of Vol. IIL to be twelve, whereas they are fourteen, as in the 

 present species. 



SLENDER-BILLED FULMAR. 



Procellaria tenuirostris. 



The other individual agrees in all respects with the first 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 pro- 

 bably a true species, as neither of the other two have the bill black in 

 any part or at any period. If it be distinct, it might be named the 

 Slender-billed Fulmar, Procellaria tenuirostris. 



The following note from Dr 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, keep- 

 ing 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, particularly 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.
