 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 are 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 differ. 

 Herring Gull, weight, 2 lbs. 1 oz., length, 1 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 3| and 3|. 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 paleish buff, 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. These 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 

 Coinish Ornithology is much indebted.
