35. Goldman on an American Kingfisher. 



[A new Kingfisher. By T. E. Goldman. Smiths. Misc. Coll. 1911.] 

 The author has got together a large series of Kingfishers 

 of the genus Ceryle allied to C. americana, and contends that 

 the Central-American form (from Mexico to Panama) and 

 the South-American forms should be referred to different 

 subspecies. Mr. Goldman proposes to call this northern 

 form Ceryle americana isfhmica. But we do not see that he 

 has established the difference of his proposed new subspecies 

 from Ceryle septentrionalis of Sliarpe. 



36. Hall on the Feather-Tracts of Sphenura. 



[The Feather-Tracts oi Sphenura hroadbenti. By Robert Hall, C.M.Z.S. 

 Proc. Roy. Soc. Tasmania, 1911, p. 23.] 



This is a minute description of the pterylosis of a some- 

 what anomalous Australian Passerine bird. Mr. Hall, 

 perhaps correctly, calls it a " disappearing genus." But he 

 does not give us any assistance in deciding where it would 

 be best placed in the system. 



37. Henshaiv on the Migration of the Pacific Plover. 



[Migration of the Pacific Plover to and from the Hawaiian Islands. 

 By Henry W. Henshaw. Smiths. Rep. 1910, p. 545.] 



Mr. Henshaw writes twenty pages about the Golden 

 Plover (Charadrius dominicus fulvus), which is stated to be 

 a regular visitor to the Hawaiian Islands on migration. 

 He supposes that they come from Alaska ; but the bird 

 has a wide range, and it would be difficult to certify its 

 supposed summer-quarters. Stragglers of some twenty or 

 thirty species of North-American birds cross the Atlantic 

 to the shores of Western Europe every year, and we see 

 no difficulty in a corresponding migration taking place on 

 the western side of North America. As Mr. Henshaw 

 suggests, a regular line of migration might thus be formed 

 and become permanent. But a much more embarrassing
