Diagnosis. Differs from the typical peregrinus in having nape and sides of head black; 
the black transverse bars on the under surface of adult specimens narrower, 
more regular and, generally, closer together; the outer and inner toes apparently 
a little longer in relation to the middle toe; size a little smaller.
