 By DR. THOMAS H. STREETS, U S. NAVY. 



By »R. R. W. $iIItJF]<:i.1>T, C. ». AltmV. 



Duiiug the years 1884 and 1885, while attacbed to the U. S. S. 

 "Patterson," and serving in the North and South Pacific, Pr. T. H. 

 Streets, U. S. Navy, availed himself of the opportunity to collect a num- 

 ber of skulls and sterna from birds which he obtained at various local- 

 ities visited by the " Patterson." These he has kindly forwarded to me 

 for description and remark, and afterwards to make such disposition of 

 them as I saw fit. In the subjoined table I give a list of these speci- 

 mens, including the skull of a specimen of Corvus corax simia-tus, col- 

 lected by me at Fort Wingate, N. Mex. 



At the i^resent writing the National Museum has in its possession 

 the manuscript of a report by me illustrated by over 400 figures, the 

 majority of which are devoted to the osteology of our arctic water birds ; 

 so when I came to look carefully over this material of Dr. Streets I 

 found that I had alreadj" figured quite a number of them in my paper. 

 In the i)resent connection I will therefore present only such figures as 

 will eventually prove additions to my far more extended labors in this 

 direction. 



As we would naturally suppose, and as will be seen in the accom- 

 panying table, the majority of the osteological specimens collected by 

 Dr. Streets are from water fowl; those from the "Eoad-runner" aud 

 Eaven forming the principal exceptions.
