preface : — " As regards nomenclature — a difficult subject — 

 the ' Ibis List/ which should be authoritative (having been 

 published in 1883 by a committee of the British Ornitholo- 

 gists^ Union) ^ unfortunately contains many errors which j 

 considering the reputation of the compilers, ought to have 

 been avoided/^ Now we challenge the writer of this passage 

 to make good his statement ; for whatever mistakes that List 

 may contain, we hold that avoidable errors in nomenclature 

 are not among them, and we consider the aljove-given re- 

 marks cast a most unjust slur upon a work to which great 

 care was devoted by some of the most competent ornitho- 

 logists of the country. 



73. Nehrkorn on his Collection of Eggs. 



[Mittlieilungen liber seine Eiersammlinig. Von A. Nehrkorn. Jahresber. 

 Ver.f. Naturw. z. Braunschweig, v. p. 117. J 



Herr Nehrkorn of Riddagshausen, near Brunswick, a 

 gentleman well known to many of us, gives a short but 

 interesting account of his celebrated Collection of Eggs, 

 which contains altogether examples of over 3000 species. 

 We do not know the exact extent of the series in the British 

 Museum, which is probably equally rich ; but it is much 

 desired by ornithologists that steps should be taken to bi'ing 

 this important part of the Natioual Bird-collection into 

 better order, so that we may know what it really contains. 



74. Pelzeln and Lorenz on types in the Vienna Museum. 

 [Typen der ornithologischen Sammlung des k. k. naturhistorischen Hof- 



niuseums. Von August von Pelzeln und Dr. Ludwig von Lorenz. 

 Theil. II., III. Ann. d. k. k. naturhistorisch. Hofmuseums, Wien, 1887, 

 pp. 191,339.] 



Messrs Pelzeln and Lorenz continue their useful list of 

 the ornithological types in the Vienna Museum, of which we 

 have already spoken (Ibis, 1887, p. 254). In the two parts 

 now before us the Passerine birds are completed.
