Size of S 5 J mm. long, 5 mm. broad; of 9 5 mm. long, 6 mm. 

 broad. These specimens have been kindly examined for me by Dr. 

 Ortmann, who finds them identical with Faxon's type from Panama, 

 and also very close to the Cape Verde P- barbatus A. Milne-Edwards. 

 This is the first recorded specimen of P. panamensis from the West 

 Indies.
