Page 49, No. 48. Read : — Hydroprogne caspia caspia (Pall). 

 Do. No. 49. Read : — Geochelidon nilocita (Gm.). 



Sterna nilotica, Gmelin, Syst. Nat. ii, 1789, p. 606 (Egypt). 



Some authors regard the form of S. E. Asia as distinct and 

 call it G. n. affin is (Horsf .). Type locality Java. 

 Page 50. For Sterna media read : — Sterna bengalensis bengalensis 

 Less. 



Stemia media Horsf. is preoccupied by Sterna media 

 Vieill., and this species must therefore be known as Sterna 

 bengalensis Less. (Traite d' Orn. 1831, p. 621. Indian Coasts). 

 Local birds appear to belong to the typical race and are, 

 therefore, S. h. bengalensis. 

 Do. No. 52. Read : — Sterna hirundo Linn. 



Sterna hirimdo, Linn., Syst. Nat. i, 1758, p. 1.S7 (Europe). 



This name considerably antedates Sterna Jinriatilis 

 Nauman. 



The Asiatic form is S. Idriindo tibetana, but the European 

 race, S. h. hirundo, is reported to occur in tlie Malay Penin- 

 sula in winter. As noted, the material we have examined is 

 inadequate for subspecific determination.
