plain lead-gray feathers in the back, the brighter colour of the mouth, the 

 slight yellow on the bill, avd the paler feet from the first plumage. 



"March 18. First Spring. — A kittiwake in first spring was quickly 

 losing the black band on neck. It has a remarkably narrow black 

 band on the wing. (In collection). 



" Third Winter or Third Spring. — In apparently adult state; had 

 the bill still strongly clouded with black, in fact, as strongly as that of 

 first spring. The orbits were almost vermilion, the feet a bright deep 

 brown tinged with yellow (orange). (In collection). 



"Another, shot same time and same age, had the orbits dull red- 

 brown, the feet similar, the bill lemon-yellow, tinged with greenish at 

 the end. 



"March 24. * * * Several others in first spring had the dark 

 band on the neck, others partly, others quite without — all were banded 

 on the wings and tail. These were observed on the wing within oar's 

 length of the boat, and were not molested." 



I have first spring kittiwakes in collection, shot in March, quite 

 devoid of the dark band on the neck, having lost it by moult, whereas 

 others seen and killed in June still had renniants of it left. 



"March 10. Bills and feet of three adult kittiwakes shot to-day: — 

 No. 1, feet dark brown, inclining to black; soles of phalanges, not 

 including the web, orange-red — the webs above paler than the 

 surrounding parts ; the tibia and the tarsal joint tinged with yellowish. 

 Bill bright chrome-yellow, greenish yellow at tip. Inside of mouth 

 and lips intense red ; orbits dark, slightly tinged with vermilion ; iris 

 deep brown. No. 2. Orbits vermilion ; bill deep chrome-yellow. 

 Rest as No. 1. No. 3. Feet hair-brown, webs paler bro«n, ankle 

 tinged with yellow ; orbits slightly tinged with red ; bill lemon- 

 yellow. 



Same date : ^' First Winter Plumage. — Two kittiwakes now lying 

 before me in first winter are strikingly dissimilar. No. 1 has quite 

 lost the black bar on neck, and is in new plumage on the back. No. 2 

 has the dark bar on the neck as full and beautiful as in October." 

 Here follows an elaborate description of the plumage, from which I 

 take the following: — "No. 1. Bill tortoiseshelled with lemon-colour 

 and black. Mouth and lips orange-red. Irides dark brown, orbits black. 

 Feet : Front of tarsi and toes and exposed part of tibia yellow flesh- 

 colour, irregularly tinged — more especially on the joints, edges of webs, 

 and outside of tarsi — with brown ; the joints on the sole are dark 

 brown, the soles of tarsi being also strongly tinged with brown.
