Vernacular names. None recorded.

Description. Differs from the preceding form in averaging rather smaller and in having the white on the tail-feathers and wings more extensive and more conspicuous, contrasting more with the adjoining dark brown.

Colours of soft parts as in the other races.

Measurements. Wing 236 to 263 mm.; culmen 45 to 48 mm.

Distribution. Red Sea and Persian Gulf; down the East coast of Africa to Mozambique and down the West coast of India to Bombay.

Nidification. The Red Sea Brown-winged Tern breeds on many of the islands in the Red Sea and Persian Gulf and Harington Bulkley had eggs said to have been taken on an island off the Mekran coast. No nest is made but the single egg is deposited in a hollow scratched by the bird in the ground. Unlike most Terns the site selected is not in the open but either among thin scrubby grass which grows on the upper part of most islands or well concealed among rocks and stones. The eggs vary as much as those of the preceding race but are decidedly smaller. One hundred average 43.8 x 31.0 mm.: maxima 46.0 X 33.1 mm.; minima 40.4 X 28.5 mm. In the Persian Gulf the breeding-season is from the end of May to July and off the Somali coast June and July.

Habits. Those of the species.
