QO GaLBALCYRIIYNCHUS rURUSIAKUS AND PlPRA C^LESTI-PILEATA 



in thc prcscnt case, trcating of a complcx misccllancous pu- 

 blication tlie printing of which rcquires a space of lime em- 

 bracing several ycais. 



The turning- point of the question is therefore as foi- 

 luws : / can prove atui have proveu, ihat as early as Febrnary 

 i()04 I puhlished aiid distrihiited a sinitiiiary description loilh 

 thc iianiing of iwo iiciu River Pnrús-hirds, one of which the 

 Gaíbaícyrhyncbits ivithout thc ■wbitc auricular patcb and from 

 that time on I continucd my efforts to gúve it fuil publicity 

 by the different means which seemed to me thc most efíi- 

 cacious for the purpose, such as exhibition and description 

 of the bird before the International Zoological Congress 

 ( ig04 ), the presentation of mounted and labelled specimens 

 to different Museums, and the cntry of the coloured figure 

 in a plate of my « iVlbum de Aves Amazonicas » in course 

 of publication. Ou {bc otbcr haud ihcre is no fair aud sqiiare 

 proof of d)c publicity of the rival Rivcr-Jurnà-bird, earlicr 

 llnui i()0) , althouoh it sails under colours of 1^04. 



Regarding the second, the Pipra. the complete lack of 

 thc slightest sober arguments to awaken doubts as to the 

 legitimate priority in my favour, relievcs me entirely of the 

 necessity of any further spinning out of a written discussion 

 and leads me not to waste more words on the subject. 



In fine I have the pleasure to be able to quote as 

 frankly on my side of this question the judgement of no 

 less authoritative ornithologists than Count Berlepsch, Pro- 

 fessor Reichenow, Dr. Sclater, Professor Studer, Dr. Reiser. 

 And there is no reason for keeping silence concerning thc 

 fact, that it is principally duc to the recommendation of the 

 first of the above named friends that I resolved to ventilatc 

 the question with fuU historical particulars in thc « Ibis », 

 to settle the matter while the details are still fresh in me- 

 mory. By so doing I simply obey the warning containcd in 

 thc ancient proverb : « Qui tacet, consentire videtur! » 



In conclusion I add fuU description of the two birds 

 formulated according to my directions and under my super- 

 vision by Dr. phil. Emifie Snethlage, assistant in the zoolo- 

 gical department of our Museum.
