connected with one another throughout life in the Palao- 

 gnathcB, while the palatines remain perfectly separated from 

 one another "caudad," and are connected only with the 

 maxillo-palatine processes " distad " ; in the Neognathos the 

 relations of these bones are of the opposite character, and 

 the palate is undoubtedly undergoing a further change. 

 The most primitive form of Avian palate is the Dromjeo- 

 gnathous, and not the Schizognathous. 



65. Reiser and Knotek on Bird-migration in Bosnia and 

 Herzegovina. 



[Ergebnisse der omitliologischen Zugsbeobachtungen in Bosnien und 

 der Hercegovina. Verfasst von Gustos Othmar Reiser und Prof. Johann 

 Knotek. Wissensch. Mitth. aus Bosnien u. Hercegovina, Bd. viii.] 



This is the report of the Committee for the observation 

 of bird-migration in Bosnia and Herzegovina for the years 

 1897-1900, commencing with the autumnal migration of 

 1897, and ending with the vernal migration of 1900. After 

 lists of the various stations and observers, the notes of the 

 latter are given, arranged in systematic order. Then follows 

 a resume of the details arranged in the order of the calendar, 

 so that we can see what species passed on each particular day. 

 In the autumnal migration of 1899, 51 species are recorded ; 

 in the vernal migration of 1900, 62. 



66. Robinson and Richmond on Venezuelan Birds. 



[An annotated List of Birds collected in the Vicinity of La Quaira 

 Venezuela. By Wirt Robinson and Charles VV. Richmond. Proc. U.S. 

 Nat. Mus. xxiv. pp. 163-178.] 



This is an account of two collections made in 1895 and 

 1900 in the vicinity of La Guaira, the seaport of Caraccas, 

 by Capt. Eobinson, together with a few specimens obtained 

 by Mr. Lyon, who accompanied Capt. Robinson on his 

 second trip. Eighty-one species are enumerated as repre- 

 sented in the series, amongst which a Wren {Microcerculus 

 pectoralis) is described as new. Most of the others are 

 well known. This is a poor result, but the avifauna of the 

 coast-district of La Guaira is evidently very meagre. The
