404 Capt. Beavan on various Indian Birds. 



MS. description of this bird, Dr. Jerdon told me it was allied to 

 S.javanica but was utterly unknown to him. 



Another species of Tern procured in Burmah, also near Tha- 

 tong, is unknown to me ; and as I am unable to refer it correctly 

 to any known species, I provisionally will assign to it the name 

 of 



-4- Sterna innotata, sp. n. 



Its position is somewhere between the genera Gelochelidon 

 and Ony chop-ion, as characterized by Dr. Jerdon. Its specific 

 characters are as follows : — Bill black, feet dull dark red ; tail 

 not forked, but nearly square in flight ; wings long, and exceed- 

 ing the tail by 2 inches ; forehead white ; head and nape brown, 

 slightly mixed with white ; a white line extends from the base 

 of the bill under the eye to behind the ear-coverts. The under 

 parts are pure white, the back and tail-coverts being a light 

 grey colour, which is also the colour of the tail, but it is tipped 

 with brown ; the scapulars are grey, also tipped with brown ; 

 the primaries are white, with brown on either side of the shafts, 

 the tips tinted with the same colour. The outermost part of 

 the inner webs of the secondary quills are pale grey ; and the 

 tertials are brownish-grey, with white shafts, and hoary or pearl- 

 grey on their'X)uter webs. The toes are only partially webbed. 

 The irides dark brown. Dimensions as follows : — Length 9"5 

 inches, wing 8*4, tail 3, tarsus *8125, bill, from front, 1"125. 

 This species was procured on October 4th, 1865, on the Thatong 

 creek, not far from the sea, and within tidal influence. I believe 

 that Dr. Jerdon saw my MS. account of this species in 1866, 

 but did not at the time refer it to any known species. 



991. Onychoprion melanauchen. Black-naped Tern. 

 Occurred to me in the Andaman Islands {cf. P. Z. S. 1866, 



p. 556; Ibis, 1867, p. 334). 



992. Onychoprion an^sthetus. Brown-winged Tern. 

 On the 8th of June 1865, in lat. N. 15° 50', long. E. 92° 25', 



I noticed that a Tern or species of Prion was seen skimming 

 over the waves, which was perhaps this species. This was in 

 the bay of Bengal, on my voyage from Calcutta to the Andaman 

 Islands.
