tributional areas of entomostraca and even of algae ; also of 

 food-fishes, of cetaceae, and marine mammals ; and of Birds, 

 inust, at some not very distant date, raise our present know- 

 ledge of these marvellous natural phenomena, and increase 

 our admiration of, and veneration for, the wondrous infini- 

 tude of wisdom displayed in creation, and in creative- 

 evolution. Some day — let us hope — we may be able to place 

 some such statistics as these in clear and definite tabulation, 

 so that " those who run may read." 



In conclusion, I take the opportunity of exhibiting these 

 specimens of birds ; which occurrences bear interest in con- 

 nection with Distribution and Migration — viz., (a) " Eecord 

 Form No. 1 " ^ (as appended), a Fork-tailed Petrel from the 

 Isle of May — " Forth " — (a new locality recorded for the 

 species) ; (p.) " Eecord Form No. 2 " (as appended), a Little 

 Gull — Lams minntus — from Kincardine-on-Forth ; and (c.) 

 "Eecord Form No. 3," a Glaucous Gull — L. glaucus — from 

 the same locality. 



Exhihition of an albino Herring Gull (Larus argentatus, Lin), 

 from Spain. 



An example of an albino Herring Gull (Z. argentatus) 

 exhibited. It was shot by Captain Halsted of H.M.S. 

 " Dauntless " near Lisbon in the Tagus in 1 852. Dr Wood- 

 cock of Anstruther, to whom it belongs, writes me that it 

 was the only individual amongst a large number of Gulls. 

 The colour of the eyes were not noted, and Dr Woodcock 

 says that any notes he has, are not at present accessible to 

 him. The rarity of albinos amongst Laridm — and indeed 

 amongst most water birds — made me consider this lusus 

 worthy of exhibition to the Society. It had previously been 

 identified by the late Mr Gould, in London, to whom Dr 

 Woodcock had shown it. It is now in the Collection of Dr 

 Woodcock at Anstruther.
