(Malacca). 



ElHot'.s name for Saigon and Bangkok bird.s, P. edwardsi, 

 will have to rank as a synonym of P. viridis, an overlooked 

 name which antedates it by many years. Hume determined 

 a Solangor specimen as " not calvus, but Elliot's new Siamese 

 species" We now have specimens from the Malay States 

 which we find to be the same as birds from Chainat, near 

 Bangkok. All these differ from t3ipical calvus of Java and 

 Sumatra by having a considerable amount of grey on the 

 head and by larger ize. A large series of P. c. calvus has 

 wings 210-230 mm: the wings of continental speciniens 

 known to us measure from 240 to 275 mm.

Sterna leucojxireid, Teiniii., Man. d' Oin. ii, 1820, [>. 746 (Hungar)'). 

 Birds from Java, India and China have received the names 

 vi joyuanica Horsf., indica Stejihens, and siviahoei Mathews, 

 respectively, but we are not in a position to determine Siam- 

 ese birds subspecifically. Mathews considers them to be 

 //. I. javauica (Horsf.). 

 Do. No. 47. Horstield named a Javanese specimen Sterna 

 grisca, and MathewtJ thinks that this name should be used 

 for the birds of S. E. Asia. Hartert only recognises the 

 typical form.
