overliaugiiig- the water, though on Wenman a few were fonud on the flat top 

 of a small islet, among the cactns and trees, on the ground. The birds there had 

 to rnn twenty yards or more to take wing, as the trees were too thick for them to 

 rise from the nest. Two or three nests were found about a thousand feet above 

 the water.

Adult males were killed on Albemarle liy Mr. Green. He notes the iris as 

 brown, the feet as black. 



This gull was observed sitting along the sand on every island that had any 

 sandy beach. There they pick np their food, and they are very seldom seen on the 

 cliffs, where Xema, f areata is seen. No nests with eggs were found, but nests that 

 were believed to be those of tliis sjtecies were observed in the low mangroves along 

 the shore on Narborongh and Indefatigable, where Lams fuliginosus was common. 

 The egg described I.e. was taken from the body of a, female shot by Mr. Hull on 

 Albemarle on November 10th, 1897. 



Specimens were taken on Indefatigable and Albemarle, and it was also seen on 

 Seymour Island.

According to Mr. Beck breeds on Culpepper Island only, though they are 

 occasionally seen at sea round some of the other islands. " They also breed on 

 Clipperton, nearly 1001) miles to the N.W. They are seen flying over the ocean at 

 least 600 miles from land, as we saw two or three nearly every day from 7° 30' N., 

 115° W., to 3o° N., 120° W., and thence to the Galapagos Islands. After leaving 

 the Galapagos they were with us nearly every day to 17 N., 11(5 W." (Beck).

A nestling from Wenman (Beck coll.) is covered with dark ashy-brown down. 

 There is only a faintly indicated supraloral line, the forehead being uniform with 

 the back. In three specimens of apparently the same age from Laysan the 

 forehead is white, while a somewhat older individnal has the forehead dark, bat the 

 supraloral stripe well marked.

We qnite agree with Mr. Saunders that it is wrong to adojit Linnaeus' name 

 parasiticus for this species (cf. Saunders, I'.Z.S. 1870 p. 326). The species of this 

 genus must therefore be called :
