Diphyllobothrium cordatum (Leuckart, 1863) 



Gedoelst, 1911 

 Host: Erignathus barbatus - bearded seal. 

 Location: Intestine. 

 Locality: Alaska. 

 Recorded by: Hilliard (1960). 



Diphyllobothrium lanceolatum (Krabbe, 1865) 

 Cooper, 1921 



Hosts: Erignathus barbatus - bearded seal; 

 Phoca vitulina richardi - harbour seal. 



Location: Intestine. 



Locality: Alaska. 



Recorded by: Stunkard and Schoenborn 

 (1936); Stunkard (1948); Hilliard (1960); 

 Rausch and Hilliard (1970). 



Remarks: Wardle, McLeod, and Stewart 

 (1947) regarded this species as identical 

 with D. phocarum (Fabricius, 1780) and 

 placed it in their new genus Cordicephalus. 

 Stunkard (1948) considered Cordicephalus 

 to be a direct synonym of Pyramicocephalus. 

 Markowski (1952) agreed with Stunkard 

 and Schoenborn (1936) in identifying this 

 species from the bearded seal as D. lanceo- 

 latum. He replaced phocarum, a species 

 quite distinct from lanceolatum, in the genus 

 Pyramicocephalus.

 ferent from the Diplogonoporus sp. from the
