Monogenetic Trematodes 



Family ACANTHOCOTYLIDAE 



Acantbocotyle pugetensis Guberlet, 1937 



Host: Raja binoculata Wash. Guberlet, 1937 



Bonham & Guberlet, 1938 



There are no other records. 



Taxonomy: This species was named by Guberlet (1937) but described by Bon- 

 ham and Guberlet (1938). Sproston (1946) is in error with Guberlet's date 

 as 1936. Both Sproston and Winters (1955) accept Guberlet as the author 

 even though the species was not described until later.

 members of the genus by Ronald (1957).
