other nestling Nightjars, and it appears that they were all met 

 with in the preceding month, July, the dates being the 12th, 15th, 

 17th, 18th, and 23rd. The Nightjar, as a summer migrant, 

 arrives here rather late, some time in May, and leaves again in 

 September, and there is scarcely a possibility of the j^oung of a 

 second brood, if hatched so late as the middle of August, being 

 sufficiently strong to leave at the period of migration. The 

 occurrence of this species after that month is very unusual ; four 

 instances only are mentioned in the new edition of Yarrell's 

 'British Birds' (vol. ii. p. 378), and I know of but one other 

 such instance myself. There is every probability that the 

 majority of these late-hatched birds must perish of cold or 

 starvation. 



Waders in Breydon H^irbour. — I was shooting on Breydou 

 "Water on September 12th, and the first bird that I secured was 

 a fine young male Turnstone, the only one I saw during the day. 

 I also killed some young Knots and Curlew Sandpipers. The 

 sexes of the latter are easily distinguished in this stage, the male 

 being much smaller than the female, and having the breast, neck, 

 and cheeks suffused with a huffy tinge, the same parts in the 

 female being white ; both have the ashy grey streaks down the 

 feathers of those parts, but they are more distinct in the female. 

 I noticed several Curlew Sandpipers mingling with the larger 

 flocks of Dunlin and Einged Plover, but occasionally during the 

 day small parties of seven or eight individuals passed by them- 

 selves. I saw a few Greenshanks and Redlegs ; amongst the 

 former was a solitary Euff, which was afterwards shot by 

 Mr. Harmer. The Curlews were, as usual, very shy, and kept 

 well out of gunshot. A Black Tern ("Blue Daw," as it is locally 

 called), in immature plumage, passed our boat, though out of 

 distance, but soon afterwards I shot an adult and immature 

 Lesser Tern. I also recognised Shoveller, Teal, and Mallard. 

 An immature Spotted Eedshank {Tutanusfascus) and a beautiful 

 specimen of the Manx Shearwater were killed a few days before 

 the date of my visit. 



Curious Variety of Waterhen. — A curious variety of the 

 Common Waterhen was shot near Norwich on April 4th, 1883, 

 and brought to me the following day for preservation. The 

 crown of the head and cheeks circling the eyes are of the usual 

 colour ; the anterior portion of the feathers of back of head of a
