Tills Proechiinys would seem to be referable to P. centralis, 

 and, by the lightness and partial obsolescence of the parietal 

 ridges, to be most nearly allied to P. c. panamensis, from 

 which, however, it differs by its conspicuously richer and 

 stronger colour and its darker tail. In the interru|)tion of 

 its parietal ridges it approaches the Bogota species P. xanthce- 

 olus, but is readily distinguishable by its broader hamular 

 processes.
