Coloration. Forehead and crown white, passing into ashy grey and then into dark brown on the nape ; lores and chin jet-black ; sides of neck, throat, and fore neck black with a grey wash ; rest of plumage blackish brown.
Younger birds are dark brown : but the lores are black and the forehead and crown white at all ages.
Bill black; iris brown ; tarsi and toes blackish brown (Layard).
Length 13 ; tail 4.75 ; wing 9; tarsus .9 ; bill from gape 2.1.
Distribution. Tropical seas generally. This species has been repeatedly seen and occasionally obtained in the Bay of Bengal. Blyth received a specimen from the mouth of the Ganges, and there is a skin in the Hume collection from Minicoy. The habits resemble those of A. stolidus.
Gygis Candida (Gm.) is probably found at times in Indian seas. There is a skin in the Leyden Museum, collected by Dussumier and labelled Bengal, and Hume believes he has twice seen this bird (S. F. vii, p. 447) ; but before including the species in the Indian list further evidence is desirable. If found, the White Noddy, as it is called, may be easily recognized by its pure white plumage, black bill, and blue irides. The tail resembles that of Anous in shape. Wing 9.5 ; tarsus very short, .6.
