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 the trees in the forest. The speci- 
mens, although resembling A. galapagensis, Sharpe, are apparently referable to 
A. stolidus. 
Sula, sp. 
Abundant, not collected. 
MALPELO ISLAND. 
Creagrus furcatus (Ntsoux). 
Larus furcatus (Néboux), Prev. et des Murs, Voy. Venus, V. Ois., p. 277. 
Creagrus furcatus, Salv., Trans. Zoöl. 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 
Island on March 5th, and saw several others upon the oliffs. The species is 
doubtless abundant there, as sea birds of several species swarm about the 
inaccessible summit of the island. 
But three specimens of this bird were known prior to the voyage of the 
** Albatross” to the Galapagos Islands in 1888, when I procured two speci- 
mens at Dalrymple Rock, 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 
colleetion, 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, Rınaw. 
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. 
! Malpelo Island is a volcanic rock in Lat. 8° 59 7” N.; Lon. 819 84’ 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.
