Henshaw, H. W. — Ornithological Report upon Collections made in 

 Portions of California, Nevada, and Oregon. By H. W. Henshaw.

Engineers, February, 1880, pp. 282-835. 



Mr. H. W. Hensbaw's " Ornithological Report" for the field seasons 

 of 1877 and 1878 is much more than a record of field observations for 

 the seasons named, treating as it does most ably, though briefly, of the 

 relationships of the members of several of the most puzzling groups of 

 North American birds. In addition to having access to a large amount 

 of material, much of which the author collected himself, he is able to 

 bring to bear upon the questions at issue an intimate knowledge of the 

 birds in life, and of the varying conditions of environment which sur- 

 round the forms treated . . .In relation to the habits of the species men- 

 tioned, the Report contains much that is new, . . . — J. A. A., Bull. Nutt.

 Vol. VII. of the Reports of the Survey of the 40th 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 investiga- 

 tion of which the author has passed the last ten years. It is unques- 

 tionably the most magnificent contribution ever made to our knowledge 

 of extinct birds . . .it is safe to say that no single memoir on fossil birds 

 hitherto published can be compared with this in accuracy of detail, in 

 beauty of illustration, and in value of results attained . /.The present 

 volume is based on the remains of more than one hundred different 

 individuals of the Odontornithes procured in the Cretaceous deposits of 

 the "West during the last ten years . . .The work of Professor Marsh, as 

 a whole, is an unmeasured advance upon all previously obtained 

 knowledge of Cretaceous birds. The present volume is divided into 

 two parts, the first treating of Hesperornis, the second of Ichthyornis and 

 Apatornis, the entire skeleton of typical species being described with 

 elaborate detail, and figured in the most perfect manner. .. .The Ap- 

 pendix presents a synopsis of the nine genera and twenty epecies of 

 American Cretaceous Birds, , . .— E. O, Bull. Nutt. Ornith. Club, Vol. V.,
