having- a pale coffee-brown ground colour, whether blurred streams, spots or blotches, are of an 

 olue or uinber-brown, and the underlying markings of different shades of inky-grey. Nine eggs 

 taken on Actseon Island, in D'Entrecasteaux Channel, South-eastern Tasmania, in November, 

 1897, measure: — Length (A) 1-95 x 1-3 inches; (B) i-Sy x 1-34 inches; (C) 1-82 x 1-27 

 inches; (D) 1-73 x 1-21 inches; (E) 1-83 x 1-26 inches; (F) 1-83 x 1-27 inches; (G) 1-87 x 

 1-33 inches; (H) i-8q x 1-28 inches; (I) 1-79 x 1-25 inches. The two latter specimens are 

 represented on Plate B. XX\'., figs. 3 and 4. 



Immature birds resemble the adults in winter plumage, having a larger extent of white on 

 the forehead, the feathers below the eye and the crown of the head and nape brownish-black, 

 finely streaked with white, the hind-neck, mantle, back, lesser and median upper wing-coverts 

 largely spotted with brownish-black, the scapulars, rump, upper tail-coverts transversely 

 barred witli the same colour and the apical portion of the central tail-feathers externally margined, 

 and the outer feathers largely tipped, with dark grey or greyish-black ; all the under surface, 

 under wing and under tail-coverts white. Wing 10-5 inches. 



On the islands of South-eastern Tasmania this Tern is a late breeder, eggs usually being 

 found at the latter end of November.

Distribution.— Wesinxn Australia, North-western .Australia, Northern Territory, Oueensland. 



^InN Australia the Panayan or " Brown- winged " Tern is widely distributed over the coast line 

 Jl. and adjacent islands of Western Australia, North-western Australia, the Northern Territory 

 and Oueensland. I have never seen or heard of a specimen being obtained in the seas of New 

 South Wales, \'ictoria or South Australia. In the "Catalogue of Birds in the British 

 Museum," however, Mr. Howard Saunders enumerates a specimen procured by Mr. John 

 MacGillivray at Moreton Bay, Southern Queensland, in January, 1845, during the \'oyage of 

 H.M.S. " Rattlesnake," so probably it does stray into the waters of Northern New South 

 Wales. Gilbert procured specimens on Houtman Abrolhos, Western Australia, where Gould
