This genus contains but two species — Bulweria columbina, which inhabits the Atlantic Ocean 

 only, and is found chiefly on or near the Canaries and Madeira, and Bulweria macgillivrayi, 

 which inhabits the Fiji Islands. These birds are said to resemble the Petrels more than any 

 other group of birds in their general habits, and like them frequent the ocean, resorting to 

 desert islands to breed, and depositing one tolerably large pure white egg in the fissures of 

 the rocks. 



Bulweria columbina, the type of the genus, has the bill about as long as the head, stout 

 at the base, compressed throughout, the unguis large, and rising almost immediately from the 

 nostrils, tubular, the tube dorsal, rather short and stout ; wings long, pointed, the first and 

 second quills about equal in length ; tail long and cuneate ; legs moderate, the tibia bare for a 

 short distance, tarsus reticulated; hind toe very small indeed, elevated, anterior toes rather 

 long and slender, the outer and middle toes about equal in length, the inner one much shorter ; 

 claws rather short, slender, curved, acute.
