MONOGRAPH OF THE PETRELS. 



uncommon in the Azores, and there were specimens in the Ponta Delgarda Museum from 

 Rosto de Cao, San Miguel, and Pico Island. 



P. bailloni occasionally wanders into the Mediterranean, for Count Arrigoni degli 

 Oddi states that he has a specimen from the Manzone Collection of Bra, which was 

 received in a fresh state, and was said to have been captured off the coast of Piedmont 

 on the 5th of October, 1895 ; and another was said to have been killed near 

 Oristano, in Sardinia, in October, 1892 (Atlant. Orn., p. 526). 



The British Islands have also been visited by this Shearwater, one having flown 

 on board a small sloop off Valentia Harbour, co. Kerry, in May, 1853. The specimen 

 was sent to Yarrell by Mr. B. Blackburn, and was identified as Pufjinus obscurus. A 

 second example was found dead near Earsham Hall, near Bungay, in Suffolk, on the 

 10th of April, 1858. Mr. Howard Saunders, who gives the above account of the capture 

 of the two British specimens, states that he had examined them both, and came to the 

 conclusion that they were referable to P. assimilis, but I have no doubt that 

 they were really P. bailloni. Two more specimens have since been procured in 

 England, one from Bexhill, on the 28th of December, 1900, and recorded by 

 Mr. Butterfield {Bull. B. 0. C, XL, p. 45) ; a second having been obtained at 

 Lydd on the 27th of November, 1905, as stated by Dr. Ticehurst {Bull. B. 0. C, 

 XVL, p. 38). 



On the Rombos Islands Lieutenant Boyd Alexander found the species nesting 

 not only in holes, but frequently beneath rocky boulders and in small clefts and 

 overhanging rocks, while in one instance a bird had made its nest beneath the boards of 

 a tumble-down hut ; in this last case the nest contained a quantity of dry grass. Its 

 weird cry resembled the sounds, " Karki-karrou, Karki-karrou," which it uttered 

 incessantly. 



Mr. Ogilvie-Grant's experience in the Salvage Islands was that this species was 

 seldom seen, but was occasionally observed during the daytime, in company with 

 P. kuhli ; he found it nesting in the sides of cliffs. 



Adult male. General colour above black, with an ashy shade, caused by the 

 indistinct margins of slaty-grey on the feathers of the back ; wing-coverts like the 

 back, the greater series with narrow white fringes to the ends of the feathers ; primary- 

 coverts and quills also black, not differing from the back ; tail-feathers black ; crown 

 of head black, like the back, as also the upper part of the lores ; lower half of lores, 

 sides of face, upper and lower edge of eyelid white, with a few blackish streaks on the 

 ear-coverts ; a white superciliary streak extending from the hinder part of the eye, 

 mottled with blackish ; cheeks and under-surf ace of body pure white, the sides of the 

 neck also mottled with blackish bars, where the white under-surf ace adjoins the black 

 of the back ; on each side of the upper breast a patch of ashy-black and white ; on the 

 sides, of the lower flanks a patch of black above the thighs, formed by the black inner 

 webs to the feathers ; under tail-coverts pure white, the lateral ones externally sooty-
