T-BULWERIA BULWERI. 



Bulwer's Petrel has been supposed to be peculiar to the 

 Atlantic^ but it has recently occurred in the Pacific Ocean 

 on Kauai, one of the Sandwich Islands (Stejneger, Proc. 

 U. S. Nat. Mus. 1890, p. 380). 



Mr. Hoist found it very common on Sulphur Island, and 

 sends three examples, in each of which the pale bar across the 

 wing formed by the grey margins of the greater wing-coverts 

 is very conspicuous, which bar is said to be absent in 

 Bulweria macgillivrayi from the Fiji Islands. These Petrels 

 flew about at night like Bats in the twilight in great numbers, 

 being extremely bold, sometimes touching the gun with the 

 tips of their wings, but the rapidity of their flight made it 

 very difficult to shoot them. Mr. Hoist succeeded in 

 dropping one of them, and afterwards secured several more 

 in the daytime, when they were found hidden away in pairs 

 among the bushes and rocks all over the island, but he was 

 unable to find any eggs. 



- SULA LEUCOGASTRA. 



The Common Booby was very abundant, and great numbers 

 of their eggs were taken early in June. They vary in size 

 from 2-7 inches by 1-7 to 24 inches by 16. 



■/-Phaeton rubricauda. 



The Red-tailed Tropic Bird was only seen on San 

 Alessandro, where it was very abundant, but kept well 

 above the range of gunshot. No skins were brought from 

 this island, but Boobies, Albatroses, and many small birds 

 were seen.
