The second point is, that the adult bird in summer plumage 

 entirely wants the broad white line on the posterior two-thirds of 

 the upper and lower eyelid. 



In the third place, though we have unfortunately no exact 

 record of the colors, the legs and feet appear to have been 

 differently colored ; the terminal dark band on the bill is not 

 half the width it is in icUht/aehis, and the rest of the bill 

 beliind the mandible appears to have been very much redder than 

 in ichthyaetus. I think too that perhaps the head and neck are a 

 more intense black. 



In the fourth place, there is very much more black on the 

 primaries (and this Schlegel notices) as I have attempted to 

 show in the following comparative statement : — 

 Larus innominatus. 



1st. — Outer web and nearly 

 terminal half black, broad 

 white band across both 

 webs near tip, much less 

 extended on outer web, 

 small white tip. 



2nd. — Terminal 2-5th black, a 

 round white spot on inner 

 web near tip, small white 

 tip. 



3?v?. — Less black, no white spot, 

 narrow white tip. 



4i/i. — Less black, otherwise 

 similar. 



5/A. — Less black, otherwise si- 

 milar. 



Qth. — Black reduced to band 

 f wide. 



Note.— In the 2nd, 3rd and 4th 

 the white of the inner web 

 runs down into the black, 

 towards the middle of the 

 web, about 1*5 in the 2nd, 

 2"0 in the 3rd, and 1*0 in 

 the 4th. 



The inner webs of 5th and 6th 

 are decidedly tinged with 

 grey, and there is a trace 

 of this towards the base on 

 the inner web of 4th and 

 the outer webs of 5th and 

 6th. 



Larus ichthyaetus. 



1st. — Outer web and a broad 

 band about 2-5 broad black- 

 ish brown, tipped for 2*5 

 white, in some immaculate, 

 in some with small black 

 band near tip on inner web. 



2nd— Terminal 2-5 th of outer 

 web black, less black on 

 inner web, a huge white 

 patch on inner web near 

 tip, a small white tippinor. 



Zrd. — Less black, otherwise si- 

 milar. 



Uh. — Black reduced to band of 

 less than 2°0 on inner webs, 

 though running a little 

 higher up the inner margin, 

 and on the outer web. 



hth. — Similar, the band on inner 

 web less than 1'5. 



QtJi. — Band about 0*5. 



Note. — Some specimens have 

 much less black than this, 

 the 6th primary in some 

 has merely a trace of a 

 black band, while in 2nd pri- 

 mary the spot on inner web 

 is not a mere spot, but is 

 continuous with the white 

 of the upper part of the in- 

 ner web, and there is a patch 

 on the outer web as well.
