appears that even many of the hardier species suffered severely at times 

 from lack of food ; many individuals of the less hardy kinds either actually 

 succumbed to the elements, or were driven away ; while migratory species 

 were generally late in their arrival the following spring. In certain cases 

 the resident species died from cold and hunger in such numbers as to ren- 

 der them much scarcer than usual the following summer. Lack of space 

 forbids an extended notice of this highly suggestive report, which relates to 

 a field of research replete with interest, but one which is evidently in too 

 great a degree ignored by most of even our best field naturalists, if we 

 recall that the range of species, and their survival over certain portions of 

 their habitat, is primarily controlled by climatic conditions, and especially 

 the severity of unusually cold seasons. — J. A. A. 



Rathbun's "Bright-Feathers."* — In typographical appearance 

 " Bright Feathers," of which Part I, devoted to the Purple Finch, is 

 before us, is an attractive piece of book-making ; the drawing of the plate 

 is passable, and the coloring is not more highly exaggerated than in many 

 plates by authors of reputation for accuracy. The text more clearly 

 betrays the hand of inexperience, not only in the general treatment of the 

 sul)jcct, but in sundry faulty peculiarities of expression, and in the pi-olix 

 melodramatic relation of the author's first acquaintance with the species, 

 whose history he in the main faithfully and in some respects happily 

 recounts. The author is evidently not wanting in knowledge of his sub- 

 ject; the faults of style he will doubtless be able to overcome as the work 

 proceeds, in which case the assumed demand for colored plates, " at nomi- 

 nal prices," of our more striking forms of bird life, accompanied with 

 attractive text, may be fairly met. — J. A. A. 



Marsh's PAL^EORNiTHOLOGY.f — We have received an advance copy 

 of this great work, issued with the permission of the Chief of Engineers in 

 advance of its publication by the Survey of the Fortieth Parallel. It is 

 the first of a series of monographs designed to make known to science the 

 extinct vertebrate life of North America, in the investigation of which 

 the author has passed the last ten years. It is unquestionably the most 

 magnificent contribution ever made to our knowledge of extinct birds. 

 Though the author's previous publications have fairly introduced these 

 remains to the notice of naturalists, thereby lessening the actual novelty of
