87. Dubois on the Genus Otocorys. 



[Remarques sui* les Alouettes du CTenre Otocorys. Par M. Alph. Dubois. 

 Bull. Mus. Roy. d'Hist. Nat. Belgique, iii. 1884, p. 223.] 



M. Dubois reviews the Larks of the genus Otocorys, and 

 proposes to reduce the various forms to one species^ which 

 " may be divided into five or six races or varieties " ! Oto- 

 corys is certainly a difiicult group to handle, but we doubt 

 whether this Avay of cutting the Gordian knot will be generally 

 adopted. M. Dubois has, perhaps, never had the opportunity 

 of examining specimens of O. bilopha. 



88. Dubois on the Hornbills. 



[Revue critique des Oi?eaux de la Famille des Bucerotides. Par M. 

 Alph. Dubois. Bull. Mus. Roy. d'Hist. Nat. Belgique, iii. 1884, p. 18.] 



]VI. Dubois uses IVIr. Elliot's IVionograph as a basis for a 

 review of the Bucerotidse. He proj)oses to reduce Mr. 

 Elliot's nineteen genera to four — Rhinoplax, Buceros, Alo- 

 phius, and Bucorvus — and many of the representative species 

 to varieties. He describes and figures as a new species 

 Buceros leucopyg'ius from the Niam-Niam country. Central 

 Africa, belonging to the section Bycanistes. He observes 

 that B. sabquadratus, Cab., of the same group, is identical 

 with B. subcylindricus, Sclater, in which we are disposed to 

 agree with him. He characterizes a form from Lake Tan- 

 ganyika, allied to B. nasutus, as Buceros nasutus, var. dubia.
