times also in Spring.

In the month of March, 1837, I had an opportunity of 
examining a couple of Gulls killed by Mr. Clement Jackson, 
of East Looe, and of comparing them with the Herring Gull, 
shot at the same time ; and the comparison has convinced 
both of us, that they arc distinct Species, though hitherto 
confounded together. Their plumage agrees in all respects 
with that of the Herring Gull, except that it seems to be 
more glossy ; and therefore I will only mention those par- 
ticulars in which they dill'er. 
Herring Gall, weight, 2 lbs. 1 oz., length, X ft. 10 in., breadth, 4 ft. 3 in. 
First new bird .... 3 .. 1 2 •• 2 5 
Second new bird ... 2f 2 .. 2 5 
In the former the bill, from the point to the angle of the 
mouth, is 3 inches, while in the two latter, this part measures 
respectively 3f and 8J. In the new Birds also the bill is far 
stouter in proportion, and much paler ; and the legs a livid 
flesh colour, the membrane of the feet being of the finest silky 
texture to the feeling and sight, while in the Herring Gull 
the colour of these parts is a palcish bull', and though a 
smaller bird, more rough and coarse. From the Glaucous 
Gull, which in size it resembles, this Bird is distinguished by 
having the quill feathers marked with black and white, as in 
the Herring Gull. The*e Birds seem equally common as the 
Herring Gull; and if it should appear that they are now for 
the first time recognized as a distinct Species, I propose to 
designate the Species by the name of the discoverer, to whom 
Cornish Ornithology is much indebted.
