as in the latter. The yonug l)ii-(l of gaittpagensis has the whitish streak above the 

 lores not distiuctl)' marked. 



Under these circnmstances this teru must be recognised as ii subspecies of 

 A. stolidus. It is spread all over the archipelago, from Culpepper and Weumau to 

 ( 'harles and Hood Islands. It is somewhat peculiar tliut dark-crowned birds, in 

 the plnmage of the immature ones, are found also during the breeding season. 



A large breeding-place was found on Jul)- 27th and July 29th on Culpepper 

 Island. This tern has always one egg only, placed in a small nest composed of a 

 few small sticks among the rocks. The eggs resemble those of otiier species of 

 Anoi(f<. Tliey are mostly very beantifnlly marked, and vary very much. The 

 ground-colour is a dead white, if held up against the light and looked through the 

 hole it is a light greenish yellow. A few eggs have a warm fleshy tinge. The 

 markings are jialer or darker reddish brown, or deep brown patches on the thick 

 end, or small roundish spots of the same colour, and all have more or less visible 

 pale mauve underlying spots. They measure .')1-.") by 3.5'o, oO by 36, 49-5 by 35, 

 45 by 34-3 mm., and so on.

One J'emalf was shot by R. H. Beck off North Albemarle on December loth, 

 189T. It is evidently not mature. The upper parts are sooty brown, the feathers of 

 the back and the scapulars have brownish buff tips. Foreueck and jugulum deep 

 sooty brown with narrow whitish tips to the feathers. Remainder of underside is 

 white, here and there sparsely speckled with deep brown. Tail feathers deep 

 brown, not barred, under and upper tail-coverts burred lilackish brown and white.

Habel was the first to call attention to the fact of albatrosses occurring in the 

 Galapagos Archipelago. In IsTO (cf. 'J'raiiK. Zool. !Suc. Loud. Vol. IX. ]i 4.j>;) we 

 learn that there are on Hood Island " two kinds of albatrosses ; one had a dark 

 blackish breast and a white hand crossing the head from one eye to the other ; the
