information and a lucid description of the county, including the 

 " Faunal Position of Santa Cruz County," taken from " Life 

 Zones and Crop Zones of the United States," by C. Hart Mer- 

 riam. Many foot note references in this part as well as in the 

 list which follows furnish a bibliography to the paper. 



The list of Land Birds impresses us as being one which 

 has been prepared with great care both from the standpoint of 

 an accurate list and in giving full credit to all who have worked 

 in the region. The annotations upon the 139 species, though 

 usually brief, are well chosen and add interest and value to the 

 list. The only improvement in the t}'pographical appearance, 

 which is unusually good, might be a different style of character 

 for the reference figures. 



The paper is a valuable contribution to our knowledge of 

 the birds of that region, and the author is to be congratulated.

On the Osteology of the Striges. {Strigidce and ^ithonidce.) 

 By R. W. Shufeldt, M. D., Proc. Am. Phil. Soc, Phila., Vol. 

 XXXIX, No. 164, pp. 665-722, pll. X-XVll. Dr. Shufeldt has 

 written much concerning the anatomy of Owls at various times 

 and in different places since the publication of what he tells us 

 was his first paper which was a memoir devoted to the 05/^o/o§->' 

 of speotyto ciiniciilaria hypogcea. in the present paper Dr. 

 Shufeldt gives "a very general contribution to the study and 

 comparison of the osteological characters presented on the part 

 of the skeletons of all of the North American species, or at least 

 genera, of 5/n^/t/^." There are a number of illustrations, 

 some of which are very fine plates and which are very satis- 

 factorily elucidated in the text. Those of the skull are espe- 

 cially well executed and serve well to illustrate the interesting 

 and valuable points Dr. Shufeldt directs attention to in the con- 

 sideration of the morphology of the cranium to which particular 

 attention is given, although the vertebral column and appendi- 

 cular skeleton are not neglected. 



In the beginning of the work. Dr. Shufeldt gives a number 

 of osteological features which have been pointed out by Mr. F. 

 E. Beddard and then supplements this by a list of his own.
