mistaken for Ibises, as, when viewed at a certain angle, the 

 beak of a Spoonbill appears to have the same curve as that 

 of an Ibis. 



Egretta garzetta immaculata. 



A pair of Lesser Eorets were seen at a laro-e pool on the 

 Lyndon River on 28 Auo-ust, 1916. I was nnable to obtain 

 a specimen, as they were very warv, but could plainly see 

 their black bills and legs through my l)inocul;irs, 



Demiegretta greyi. 



On 26 August, 1913, a pair of Wliite Reef-Herons was 

 seen at the Yardie Creek. On 5 July, 1916, I shot a white 

 specimen on the beach at Point Cloates, untloubtedly 

 breeding. On 23 August, 1916, 1 took three fresh eggs from 

 the nest of a pair of Blue Reef-Herons, built on a low cliflP, 

 fifty miles south of Point Cloates. When l\1i-. Highain and 

 I were at Cape Leeuwin on 9 April, 1919, he shot a Reef- 

 Heron, and when I coniparful it, in November last, with 

 other specimens in my collection from furtlier north, I 

 found that it differed from any of them ; so I sent it on 

 to Mr, Mathews with other examples, calling his attention 

 to the differences. He described it as Demiec/rdta matook 

 carteri subsp. nov. in Bull. B. 0. C. vol. xl. p. 75. 



Nycticorax caledonicus hilli, 



Australian Night-Herons were extremely abundant, both 

 in adult and immature spotted plumage, on the Vasse River 

 in February and March 191t), but I did not see a single 

 bird there in April 1919. 



Butorides striata stagnatilis. 



Only one Little Mangrove-Bittern was observed. It was 

 a breeding male, and was obtained in some mangroves near 

 Carnarvon on 23 Septend)er, 1911, but I could find no nest. 

 As is usual with this bird, it was very wary, and after being 

 flushed several times and eventually "marked down '^ in a 

 small patch of mangroves, it assumed an erect position, witli 

 its bill pointing upwards, and was then difficult to see amongst 

 the straight yellowish stems of the young mangroves.
