Kittlitz {Reise II.) also describes the iris as bladrish brown, Gould (JB. Australia) 

 iis black. 



Eggs were found on Saipan on July 28th and Angnst 11th. They mostly 

 perfectly agree with the eggs of this species, as described and figured elsewhere, 

 especially with those figured in Part I. of Walter Rothschild's Avi/auna of Laysan, 

 and are of the same size. They vary much, however, in size, shape, and colour. 

 One eg'^ is rather h)ngish, measuring 44 : 31 '4 mm., and being white with very pale 

 and small greyish and brownish grey spots. Another egg is nearly spherical, 

 measuring 33-5 : 32'9 mm., and dirty yellowish, all over sprinkled and spotted with 

 darker and paler brown and greyish. One is dirty brown, marked all over with 

 dark brown spots, patches, and zigzag lines. Some specimens have a ringlike zone, 

 but all, except the longish white one, are more or less characteristic Gygis eggs. 

 Specimens from the Kermadec Islands are i|uite similar, but on an average (though 

 not all) a little larger. 



All the eggs were found witliout any nest on the forks of low trees, every bird 

 laying one egg only. 



41. Anous stolidus (Linn.) (Oust. II. p. 59). 

 Guam, three specimens from April. 



Mons. Onstalet enumerates further : Ajwus leucocapillus Gould, Phaeton 

 catididits Temm., Sula Icucogastra Bodd., Hula piscatrix L., Tachi/jjetes qquila var. 

 minor, Larits tegae PalmSn, Pujfinus tenebrosus Pelz., which Salvin unites with 

 F. obscurus, but which Onstalet considers to be difl'erent, Pujfinws obscurus (Gm.), 

 Viomeilea, nigripes And., Fuligula cristata Steph. None of these (which I quote 

 witli Oustalet's names) were sent by our men, who had no boat of their own, and 

 who did not visit Rota and Agrigan, where most of these were found. 



We have thus the following list of the birds known to occur in the Marianne 

 islands, and it is not to be expected that many more will be found, although 

 collections from Rota and the islands north of Saipan would still be of interest, 

 while we may accept that Guam and Saipan, where most of Marche's collections 

 were formed, and where Mr. Owston's Japanese collectors did their careful work, 

 are now ornithologically very well known: —
