Much as it is hoped that light has been shed upon the 

 ornithology of Lower California, especially over the region 

 traveled, the writer knows, more than anyone, of the imper- 

 fections of the present catalogue and the difficulty of treat- 

 ing this subject under peculiarly adverse circumstances, but 

 ventures to hope that it may meet with favor and prove of 

 interest and assistance to ornithologists.
