18 TREMATODES OF THE PACIFIC NORTHWEST 



Additional hosts have been siunmarized bj' Dollfus, (1937b) but must 

 be examined under the various synonyms as noted above. He listed hosts from 

 the Mediterranean, Norway, France, Canada, New Zealand, Alaska, Sweden, 

 Belgium, Great Britain, Chile, Siberia, and Australia. Nicoll (1915b) listed 

 additional British hosts; Rees (1953) listed hosts from Iceland, and Heller 

 (1949) listed hosts from Canada. 



Morphology: Manter (1926) described this worm in great detail. 



Biology: The life history is not completely known. The adult, egg, and miri- 

 cidium were described by Manter (1926), and metacercariae have been found 

 encysted in Glyptocephaliis cynoglossus and Chimaera nionstrosa. The defini- 

 tive host is usually a selachian (Nicoll, 1913; Dollfus, 1937b). 



Otodistomum plicatum Kay, 1947 



Host : Hexanthus griseus Wash. Kay, 1947 



There are no other records of this form. 



Family BRACHYLAEMIDAE 



Brachylaime fuscatus (Rudolphi, 1819) 



Synonyms: Distonui fuscatuin Rudolphi, 1819 



Harmostommn nicolli Witenberg, 1925 



H. (Harmostonmm) fuscatum Witenberg, 1925 



Harmostomum pcUuciduvi Werby, 1928 



Bradhylacma pcllticichim (Werby, 1928) Sinitsin, 1931 



Host : Turdus migratoriiis Wash. Werby, 1928a 



Additional hosts are listed in Yamaguti (1958). 



Taxonom}' : Kruidenier and Gallicchio ( 1959) have shown the correct designa- 

 tion of the genus to be Brachylaime. 



Morphology: Skrjabin (1948) described and figured the worm. Dawes (1946) 

 also described the form. 



Biology : The life history has been partially worked out by Joyeaux, Baer, and 

 Timon-David (1934) and by Timon-David (1954) and involves a cer- 

 caraeum developing in the kidney of Helix pisana and becoming an adult 

 in passerine birds. 



Glaphyrostomum propinquum Braun, 1901 



Synonym: Glaphyrostomtuii sanguinolentum Werby, 1928 (Sinitsin, 1931) 



Host : Opornis tolmiei Wash. Werby, 1928b 



Additional hosts are listed in Yamaguti (1958). 



Taxonomy : There is some disagreement as to the correct disposition of Werby 's 

 species. Dawes (1946) and Yamaguti (1958) accepted Sinitsin's (1931b) 

 proposal, but Skrjabin (1948) retained Werby's species.
