SHUFELDT’S MEMOIR ON THE OSTEOLOGY OF 
SPEOTYTO CUNICULARIA HYPOGASA. 
BY DR. ELLIOTT COUES, U. S. A. 
Dr. R. W. Shufeldt, of the U. S. Army, has sent me his Memoir 
on the Osteology of the Burrowing Owl, — an extended and very 
elaborate paper, describing the skeleton of this species in great detail. 
This contribution was not prepared for the Bulletin of the Nuttall 
Club, occupying as it does far more space than could be given in 
this periodical to any single article ; and I shall doubtless be able 
to make arrangements for its publication in full in another con- 
nection, as originally designed by the author. Meanwhile, however, 
I have the pleasure of presenting to the readers of the Bulletin 
the three plates illustrating the article, engraved by Thomas Sin- 
clair and Son, of Philadelphia, from the original drawings made by 
the author, together with the explanation. 
Dr. Schufeldt has applied himself with great zeal and assiduity 
to the anatomy of this bird, designing to exhibit, from original dis- 
sections, the entire structure of the species. To judge from the 
osteological study already completed, an exhaustive treatise on the 
subject will result from the author’s researches.
