loo Anthony, The Fulmars of Southern Califoriiia. I April 



Type (light phase), No. 4914, Coll. A. W. A. Otf San Diego, Cali- 

 fornia, Feb. 21, 1894. General plumage white. Mantle pearly gray, 

 rather darker than light phase of glupischa in my collection. Tertials 

 white with brownish gray clouding. 



Dark Phase. Type No. 5596, Coll. A. W. A. Off San Diego, California, 

 Oct. 16, 1894. Uniform deep sooty plumbeous. Bill yellow. Iris brown. 



The proposed race differs from fninor exactly as does glupischa 

 from glacialis. The plumage and color of the bill are practically as 

 in glupischa, from which it differs, as above stated, in smaller size, 

 as will be shown in the following tables. 



Unfortunately I have mislaid the measurements of a part of my 

 series, which is now inaccessible, but the results as given in the 

 tables below would not be materially changed by the addition of 

 measurements of the series I have examined. 



I have but a single skin of glacialis to use in comparison. 

 This is an adult in light plumage from Melville Bay. As 

 compared with my skins of glupischa taken off this coast the 

 mantle is a rather darker gray. This, however, is doubtless but 

 an individual variation. The bill is noticeably smaller than 

 in Pacific specimens I have seen, the nasal tubes being fully 

 4 mm. shorter than in Pacific Fulmars of otherwise the same 

 general measurements. As I can find no mention by various 

 writers of this apparent difference in the size of the bills I am 

 forced to believe that there is considerable variation, though the 

 measurements of glupischa before me are reasonably constant. 



A specimen of rodgersii (No. 4913, Coll. A. W. A., Feb. 17, 

 1894, off San Diego, California) has the primaries slaty, the inner 

 web with a sharply defined white wedge reaching to within 

 45 mm. of the end of the first primary and leaving a dark shaft 

 line 5 mm. wide. The dusky on the tips of the primaries 

 gradually becomes less and disappears at the ninth. The slaty 

 shaft line becomes •also narrower and disappears on the sixth. 



In a younger specimen shot the same day • the wedge is very 

 poorly defined and much less purely white (grayish). The mantle 

 is much more continuously gray and the tail from above dusky 

 gray. In the adult the tail is pure white with a dusky terminal 

 bar of, 12-15 mm.; central rectrices with but a slight clouding 

 of dusky at the end.
