27<> Proceedings of the Royal Physical Society. 



M. Iunarium, G. 1 — One specimen of what may be this, from Common Scoter, 

 Musselburgh Bay. Dec. 1887; but the status of this form, which was described 

 from the same species of duck, is not satisfactory. 



M. phasopus, N. (ridibundus, D.) — From Black-headed Gull, Loch Leven, 

 May 1912; and also, so far as I can judge, from Little Gull, Dunbar, Oct. 

 Denny's figure is much too dark. 



M. obtusum, N. (1 transversum, D). — From Kittiwake, Kincardine-on-Forth, 

 Jan. 1885 Piaget thought this might be merely a variety of the last, and 

 Kellogg treats it as such. 



Colpocephalum flavescens, N. — From Rough-legged Buzzard, Gorebridge, 

 Sept. 1906. 



C subpachygaster, P. — Mr Waterston informs me that he has this from a 

 Barn Owl (Strix Jlammea) got at Cramond [From same species, Wigtownshire.] 



C. subsequale, N. — From Raven, Strathyre, 1908, also [Shetland, Dec. 1905 

 and Oban, Sept.]; Hooded Crow, Dirleton, Dec. 1884; Carrion Crow, Elie, Oct. ; 

 and Rook, Kirkliston, March 1909. 



C. importunum, N. — Many on Common Heron, Portmore Loch, Oct. 1906 ; 

 and Loch Leven, August. 



C. umbrinum, P. (? trilobatum, G.)— One specimen from Little Stint, Aberlady 

 Bay, Sept. 1885, agrees well with Piaget's figure. 



C. ochraceum, N. — From Lapwing, Colzium, Pentlands, March 1890, and 

 Currie, June 1906; Jack Snipe (Gallinago gallimda), Luffness, Jan. 1886; 

 Oystercatcher and Whimbrel, North Berwick, Aug. 1911. 



C. bicolor, P. — From Turnstone, Longniddry, Nov. 1885, Dunbar and Isle of 

 May, Sept. last. 1 



C. maurum, N. (piceum, D.) — One ?, of what I take to be this, from Little 

 Gull, Dunbar, Oct. 



Nitzschia pulicaris, N. (bnrmeisteri, D.) — From Swift (Cypselus apus), Edinburgh 

 and Dunipace, August, and Linlithgow, June 1912. In some respects my 

 specimens agree with N, tibialis, P., which, however, does not seem to me to be a 

 good species. 



Trinoton conspurcatum, N. — From Bewick's Swan, Aberlady Bay, Feb. 1891. 



T. luridum, N. — From Pintail, off Bo'ness, Oct. 1884 ; Teal, near Culross, 

 Jan. 1885 ; and Mallard, near Edinburgh, Aug., and North Berwick, Dec. 1906. 



T. lituratum, N. (squalidum, D.) — One from Wigeon, Duddingston Loch, 

 Sept. 1906. 



Physostomum bombycillse, D. {intermedium, P.)? — One from Snow Bunting, 

 North Berwick, Nov. 1906. I place it under this name, because Denny states 

 that he had seen his bombycillce from the Snow Bunting, as well as from the 

 Waxwing. 



Postscript, 22nd Oct. 1912.— To the above list I have to add: — Nirmus 

 ha^matopi (L.), D. (ochropygus,~S.) — From Oystercatcher, North Berwick. 



Reference to the figure of Kellogg's Docophorus-like Giebelia, from Pacific 

 Shearwaters, in "Genera Insectorum," suggests the probability of my D. aviator 

 from the Manx Shearwater (pp. 268 and 270) belonging to that genus. 



' I have shown specimens to Mr R. S. Bagnall, by whom the species was first recorded 

 as British in Feb. this year.
