ii 4 ANNALS OF SCOTTISH NATURAL HISTORY 



from the island of Benbecula, has been found in collections 

 from Unst in Shetland and from the Mainland of Orkney. 



Although I have examined from 40 to 50 samples of 

 Campylopus Shawii from various localities, but more especi- 

 ally from Tarbert, as well as samples of C. setifolius from 

 five places in Ireland, I have not discovered any osculating 

 pores in any of the leaf-cells. On a specimen of the latter 

 from the Gap of Dunloe in Ireland, picked up in 1864 by 

 the late Mr. G. E. Hunt, I find abundance of these pores 

 on the long characteristic cells, and still seen connected in 

 two or three instances by slender tubes. These cells are the 

 longest of any in the leaf, and, in this specimen, measure 

 from 60 to 90 by 9 to 13, and are undulatingly fusiform 

 or oblong fusiform. In all the specimens of the various 

 Campylopi examined these porous cells have only been 

 found in rather well - defined, elongated groups, situated 

 close to the nerve and a little up from the base. Mr. 

 Hunt's specimen is rather laxly tufted, 4 inches long, but 

 affords evidence that the stems must have been consider- 

 ably longer. As the original specimens (of which I still 

 retain a few stems) on which Wilson founded the species 

 do not show any such cells or pores, I propose to name this 

 moss Cavipylopns porophorus. 



I am persuaded that I possess from Tarbert specimens 

 which can scarcely be otherwise reckoned than as forms of 

 C. setifolius a moss, as I now know, very closely allied 

 to C. Shawii. I shall have more to say under this head on 

 another occasion. 



ZOOLOGICAL NOTES. 



Barred Warbler, Pied Wagtail, Mealy Redpoll, and Snowy Owl 

 in Barra. On the 2gth of October last I shot a Barred Warbler 

 (Sylvia nisoria) in my garden at Eoligary, and Mr. John Paterson 

 and Mr. Wm. Eagle Clarke, who have examined the specimen, 

 pronounce it to be a young example. Mr. Eagle Clarke tells 

 me that it is the third known Scottish example, and that all of 

 them, singular to say, have been obtained in the western isles. 

 I have presented the specimen to the Edinburgh Museum, to be 

 incorporated with the fine collection of Scottish birds in that 

 national institution.
