From the Bulletin of the Museum of Comparative Zoology at 

 Harvard College, Vol. XL. No. 3. 



These three notable papers by Dr. Strong are results of his 

 course of study in the graduate department of Harvard Universi- 

 ty. The last named paper summarizes the results of investigations 

 on the development of color in feathers, and incidentally shows 

 the extreme improbability of change of color in feathers without 

 molt, except by the wearing away of the tips of feathers, which 

 will simply eliminate that part of the feather with its color. This 

 has been so carefully and thoroughly done that we may accept as fi- 

 nal the conclusions reached. In fully grown feathers the change of 

 the pattern of color by a redistribution of its pigment is not possi- 

 ble. L. J. 



On the Classification of Certain Groups of Birds (Supersubor- 

 ders: Archornithiformes; Dromaeognatliae, Odontohoicae.) by R. W. 

 Shufeldt. 



Reprint from the American Naturalist, Vol. XXXVH, No. 433. 

 January, 1903. 



This paper is one of a series in which iDr. Shufeldt is giving the 

 results of a great amount of study upon the osteology of birds, 

 both extinct and living. The classification of extinct birds must 

 necessarily be based upon the bones. Comparison with the skele- 

 tons of modern birds forms a basis for determining the relative 

 position which those old forms should occupy in a general 

 scheme of classification. Our thanks are due Dr. Shufeldt for the 

 pains he has taken to bring order out of chaos where the ancient 

 fossil forms are concerned, as well as for his contributions to mod- 

 ern classification based upon skeletal characters. L. J.
