Synonym: Genolinea robusta Lloyd, 1938 (Manter, 1954) 



Hosts: Scorpaenichthys marmoratus B.C. McFarlane, 1936 



5". marmoratus Wash. Lloyd, 1938 



Ophiodon elongatus Wash. Lloyd, 1938 



Leptocoitus armatus Ore. McCauley, 1960 



Enophrys bison Ore. McCauley, 1960 



Blepsias cirrhosis Ore. McCauley, 1960 



The only other report of this form was from Maine (Manter, 1925). 



Genolinea manteri Lloyd, 1938

Dasycottus setiger Wash. Ching, 1960b 



This parasite is unknown outside of the Pacific Northwest. Lloyd (1938) 

 has adequately described the form. Nothing is known of its life history. 



Genolinea montereyensis Annereaux, 1947 



Host: Leptocottus arntattis Ore. McCauley, 1960 



The only other report of this trematode is that of Annereaux (1947) from 

 California. 



Genolinea oncorhynchi Margolis and Adams, 1956 



Host: Oncorhynchus gorbuscha B.C. Margolis & Adams, 1956 



This is the only report of this trematode. 



Halipegus occidualis Stafford, 1905 



Synonym: Halipegus lermensis Caballero, 1941 (Caballero, 1948) 



Hosts: Rana aurora Ore. Macv & Demott. 1957; Macy,

This form has been reported from Eastern Canada b}^ Stafford (1904), 

 Maryland by KruU (1935b), and Mexico by Caballero (1941). 



Morphology: This form has been described by Krull (1935b) and Mac}', 

 Cook, and Demott (1960). 



Biology: Krull (1933b, 1935b), Macy and Demott (1957), and Macy, Cook, 

 and Demott (1%0) worked out the life cycle experimentally. In Oregon 

 (Macy and Demott, 1957; Macy, Cook, and Demott, 1960) found that 

 cystophorus cercariae develop in Planorbis trivolvis subcrenatus and pene- 

 trate the ostracod Cypridopsis vidua before reaching the definitive host. 

 Krull (1935b) was able to get cercariae to penetrate several species of 

 Cyclops and a dragon fly.
