Abstract

Van Cleave (1918) first described briefly the acanthocephalan, Polymorphus obtusus, from the water-turkey, Anhinga anhinga, and later (1925) identified as P. obtusus a specimen from the great blue heron, Ardea herodias. No subsequent de- scription of this species has been found. Fourteen acanthocephala identified as P. obtusus have been recovered from the intestine of the ruddy duck, Erismatura jamaicensis. Since the writer has observed a number of morphological details not included in Van Cleave's papers, it seems desirable to extend the description of this species.
