The single egg, mentioned above, measures 25.4x19.5 mm. 
It is elliptical oval in shape, inclining to oval, and is dead 
white, with a very few dark specks, so minute and scattered as 
to be scarcely discernible. 
Oceanodroma tethys (Bonaparte): GaLapacos PETREL 
Coves—Procellaria tethys, I, 80, 90, V, 192. 
Satvin—Procellaria tethys, 343, 346. 
GopmMaNn—Procellaria tethys, xxxv, 4, pl. 2. 
Scarcely anything has been written concerning the Gala- 
pagos Petrel, and, as might be expected, the results of the 
Academy’s two ocean expeditions add somewhat to the com- 
mon stock of information. The known northern range of the 
species was considerably extended by both expeditions. Dur- 
ing the one to the Galapagos Islands, individuals first made 
their appearance on July 21, 1905, in latitude 23° 32 N., 
longitude 113° 4° W., the position where the Black-footed 
Albatrosses parted company with the schooner Academy. On 
the following day, about a degree further south, a dozen speci- 
mens of the Galapagos Petrel were secured, and from this 
time forward, this petrel is prominent in Mr. Gifford’s notes.
