Wales, Mr. North exhibited specimens of two birds from the 

 Gilbert Islands (lately annexed by Great Britain) obtained 

 by the British Resident^ Mr. Swaync. One of these was the 

 Common Shoveler [Spatula clijpeata), which occasionally 

 straggles thus far. The other was a nomadic Cuckoo ( Urodij- 

 namis taite7isis), said to be the only land-bird found in the 

 Gilbert group^ where, however, it does not breed. 



1 19. Richmond on a new Genus of Trogons. 



[Diagnosis of a new Genus of Trogons {Heterotrorjon), based on Hapa- 

 loderma vittatum of Shelley ; with a Description of the Female of that 

 Species. By Charles W. Richmond. Proc. U.S. Xat. Mus. xvii. p. 601.] 



Mr. Richmond has examined a series of specimens of the 

 rare Trogon [Hapaloderma vittatum, Shelley) obtained by 

 Dr. Abbott on Mount Kilimanjaro, and has come to the con- 

 clusion that this species should be generieally separated from 

 Hapaloderma narina. He proposes the name Heterotrogon 

 for the genus, and gives full descriptions of both sexes.

 Seebohm. London : Porter, 1895.]

 original research, he has had an opportunity of studying what 

 Fiirbringer, Lydekker, Gadow and others have written upon 

 this subject. The result has led him to see the necessity of 

 certain corrections and modifications in his original views, 

 which are put before us in the present pamphlet. 



Mr. Seebohm now divides existing birds into five "Sub- 

 classes^' : Sph8eniscomorph3e,Pelargomorph8e,Coraciomorphse, 

 jEgithomorphse, and Dromseomorphse. These subclasses are 

 divided into 31 suborders, the limits of which, as a general 

 rule, agree very fairly with what are nowadays considered by 

 most systematists as the leading primary divisions of the whole
