Grreater Shearwater, Puffinus major ; occasionally seen, and speci- 

 mens obtained from Mount's-bay. 



Manx Shearwater, P. angloru7n; common at Soilly, where it 

 annually breeds in rabbit-holes. 



Fulmar Petrel, Procellaria glacialis ; very rarely observed in the 

 south of England : one specimen taken alive at the Land's- 

 end. 



Wilson's Petrel, P. Wilsonii; one specimen only obtained from 

 Cornwall, and this was found dead in a field near Polperro ; 

 it passed into the hands of Mr. Couch, who forwarded it 

 to Mr. Yarrell, whose figure of this bird was taken from 

 the Cornish specimen. 



Fork-tailed Petrel, P. Leacliii; several specimens of this small 

 petrel have from time to time been obtained on our coasts. 



Storm Petrel, P. pelagica ; of frequent occurrence in the summer 

 months, and observed at a distance of five or six miles at 

 sea. Abundant at SciHy, where they breed. Egg white, 

 with a rufous zone at the larger end. 



APPENDIX. 



From the year 1843 to the present time much attention has 

 been given to the Natural History of the Isles of Scilly : valu- 

 able contributions have been given in our Greological and 

 Natural History Reports on the geology of the islands, and on 

 the botanical, entomological, and other natural productions of this 

 western archipelago, and a large amount of statistical information 

 as to the specimens recorded has appeared in the pages of the 

 "Zoologist" since the above period. The following list of the 

 occurrences and captures of some of our rarer and more inter- 

 esting British species of birds in these islands (most of our 

 common way-side birds being found there) may, it is hoped, 

 keep alive an interest in the natural history of this district, 

 remembering that from the peculiar westerly and southerly 

 position of the group, there alwaj^s exist chances of stragglers 

 being found there imder disturbed states of the elements, or as 

 a favourable resting-place in the great northern and southern 

 migratorial movements of birds, as the following list will show.
