In addition to the Shearwater of which Mr. Stevenson lias just 
been speaking {antea p. 467), there are three other species of the 
genus Pitmans known to have occurred in England, and one 
other (P. Jciihli, Boie), which appears to be restricted to the 
Mediterranean, and has not at present been recognized as 
occurring elsewhere. Of the British species, the ^lanx Shear- 
water (P. anglorum) is sufficiently well known, but it seems 
probable that P. (/riseiis has been occasionally mistaken for the 
immature stage of the larger, white-breasted P. major. I have the 
pleasure of exhibiting both the latter species, and, I think, with 
the birds before us, the specific distinctions will be sufficiently 
apparent. The larger bird, P. viajor, was taken at Plymouth 
by Mr. Gatcombe, and by him presented to our IMuseum ; but 
the smaller bird, P. grissus, has the additional interest of 
having been obtained on our own coast of Xorfolk as long ago 
as the 26th July, 1851. I purchased the bird on the table 
alive, of a boy who caught it at the mouth of the river Ouse 
as he was returning to Lynn in a fishing-boat; it -was found 
sleeping on the water in the afternoon of the 2.5th Julj^, and secured 
alive. At that time I had a number of living Gulls and Ducks 
in a netted-in garden, and the Shearwater was added to the 
collection. It only survived five days ; probably having been 
injured at the time of its capture; but I had a good oppor- 
tunity of observing its actions during the time it lived. It 
passed the day sleeping, showdng no desire to hide; but as
