TOWNSEND : BIRDS FROM COCOS AND MALPELO ISLANDS. 125 



Anous stolidus, Linn. 



Sterna stolida, Linn., Syst. Nat., Vol. I. p. 227. 



Anous stolidus, Ridgw., Proc. U. S. N. M., Vol. XII. p. 116. 



Abundant ; four specimens collected. This species was noticed as most 

 numerous, flying among the branches of tlie trees in the forest. The speci- 

 mens, although resembling A. galapagensis, Sharpe, are apparently referable to 

 A . stolidus. 



Siila, sp. 

 Abundant, not collected. 



MALPELO ISLAND.i 



Creagrus furcatus (Neboux).

 Creagrus furcatus, Salv., Trans. Zool. Soc. Lond., Vol. IX. Part IX. p. 506. 

 Creagrus furcatus, Ridgw., Proc. U. S. N. M., Vol. XII. p. 117. 



I shot four specimens of this rare gull during our short stop at Malpelo 

 Lsland on March 5th, and saw several others upon the cliff's. The species is 

 doubtless abundant there, as sea birds of several species swarm about the 

 inaccessible summit of the i.sland. 



But three specimens of this bird were known prior to the voyage of the 

 "Albatross" to the Galap.igos Islands in 1888, when I procured two speci- 

 mens at Dalrymple Eock, Chatham Island. Malpelo Island is a new locality 

 for Creagrus furcatus, the other examples known having all come from the 

 Galapagos, with the exception of one from Peru, and the original specimen 

 procured during the voyage of the "Venus," 1836-39, attributed, doubtless 

 erroneously, to Monterey, California. Unless contained in the Baur and Adams 

 collection, only nine specimens are known at the present time, although the 

 bird was discovered more than fifty years ago. 



PETRELS OBTAINED AT SEA. 



Oceanodroma cryptoleucuera, Ridgw. 



Three specimens obtained off Wenman Island, Galapagos, April 4. They 

 were attracted on board by the electric lights used on deck while dredging at 

 night. 



1 Malpelo Island is a volcanic rock in Lat. 8° 59' 7" N. ; Lon. 81° 34' 27" W. 

 It is less than a mile in greatest length, with a height of over 800 feet. It is inac- 

 cessible and without vegetation other than a small patch of bushes.
