But if these alone are to be depended upon, it becomes necessary to limit 
the distribution of ludovicianus proper to the Gulf States, Georgia and the 
Carolinas, if not strictly to Florida, and to refer all representatives from 
the United States at large, east of California, to excubitorides: and this 
course, I believe, will ultimately have to be adopted. The proper position 
of the dark California form which is so curiously like ludovicianus remains 
to be satisfactorily determined.
