APPENDIX. 157 



By these remarks one is naturally led to observe the often-noticed correspondence of forms 

 in the Old and New World ; as, for instance, the Ostrich of Africa represented by the Rhea of

America, the Camel of the Old World by the Llama of America, the Lion by the Puma, and 

 many other similar representations. 



In the work on ' Pterylographie,' published by Ch. L. Nitzsch, the author, who evidently 

 has paid great attention to the subject, says, that " these powder-down patches are found (but in 

 a much smaller degree) in the genus Tinamus, one or two Parrots, and also in some of the Birds 

 of Prey." I have not, however, met with them in any group except the Ardece and their allies. 

 I can assert most positively that no traces of these patches exist in the Pelicans, Storks, or Cranes. 

 I have also taken considerable trouble with Scopus. This bird is considered by Prof. Reinhardt 

 to be closely allied to Bcdaeniceps. I cannot find anything to justify such a belief; the skins and 

 skulls of the two birds are so entirely different, that it is useless to enter into any further details 

 respecting them. 1 



There is one thing, however, that I wish to remark, and I do so with considerable uneasi- 

 ness lest I should be accused of casting a doubt upon the veracity of the gentleman to whom we 

 are indebted for the first living specimens of this rare bird ; and this consideration would have 

 prevented my making the remark, had not my great desire been to call attention to the subject 

 in the hope of obtaining a truthful explanation of what appears to me inexplicable I refer to the 

 statement, made by Mr. Petherick, that Balceniccps runs about in search of food immediately 

 after it is hatched. If this is true, it is one of -the most extraordinary facts I have yet met with. 



spreading out of the wings, in which position the beautiful markings upon every feather are finely 

 displayed. I have so frequently seen this attitude assumed by both these birds, that I am satisfied it 

 is not merely an accidental thing. 



1 I may remark that I cannot agree with Mr. Bartlett's views as to the affinities of Balceniceps, 

 which, in spite of its powder-down patches, must, I think, be referred to the Storks (Ciconiida),
