Location: Lungs. 



Locality: California (wild and captive ani- 

 mals); Baltimore Zoo.

 Dougherty and Herman (1947); Johnston 

 and Ridgway (1969); Dailey (1970) ; Dailey

Parafilaroides nanus Dougherty and Herman, 

 1947 

 Syns.: Filaroides sp. of Dougherty, 1943. 

 Parafilaroides sp. of Dougherty, 

 1946. 

 Host: Eumetopias jubatus - Steller sea lion. 

 Location: Lungs. 



Locality: California (San Diego Zoo). 

 Recorded by: Dougherty (1943b, 1946); 

 Dougherty and Herman (1947). 



Parafilaroides prolificus Dougherty and Her- 

 man, 1947 

 Syns.: Filaroides sp. of Dougherty, 1943. 

 Parafilaroides sp. of Dougherty, 

 1946. 

 Host: Eumetopias jubatus - Steller sea lion. 

 Location: Lungs. 



Locality: California (San Diego Zoo). 

 Recorded by: Dougherty (1943b, 1946); 

 Dougherty and Herman (1947). 



Pharurus convolutus (Kiihn, 1829) Dougherty, 

 1943 



Host: Phocoena phocoena - harbour porpoise. 



Location: Lungs. 



Localities: Washington; California. 



Recorded by: Dougherty (1943a); Scheffer 

 and Slipp (1948). 



Remarks: Soviet authors (see Skrjabin et al., 

 1952; Delyamure, 1955) do not recognize 

 Pharurus Leuckart, 1848 as a valid genus. 

 They use the designation Torynurus convo- 

 lutus (Kiihn, 1829) Baylis and Daubney, 

 1925 for this species. Dougherty (1943a) 

 considered Torynurus Baylis and Daubney, 

 1925 as a synonym of Pharurus. 



Pharurus oserkaiae (Skrjabin, 1942) Dough- 

 erty, 1949 

 Host: Delphinapterus leucas - white whale. 

 Location: Head sinuses. 

 Locality: Alaska. 



Recorded by: Babero and Thomas (1960). 



Remarks: Dougherty (1949) considered Oto- 

 phocaenurus Skrjabin, 1942 to be a synonym 

 of Pharurus Leukart, 1848, and transferred 

 0. oserskoi Skrjabin, 1942 to the latter genus. 

 This view was upheld by Babero and Thomas 

 (1960) but not by Soviet authors (see Skr- 

 jabin et al., 1952; Delyamure, 1955). The 

 specific name was modified by Dougherty 

 ( 1949) from oserskoi to oserskaiaae and sub- 

 sequently emended (Dougherty, 1951) to 

 oserskaiae. Babero and Thomas (1960) 

 spelled the specific name oserkaiae. 



Placentonema sp. 



Host: Phocoenoides dalli - Dall porpoise. 

 Location: Mammary glands. 

 Locality: California. 



Recorded by: Ridgway (1966) ; Johnston and 

 Ridgway (1969). 



Placentonema gigantissima Gubanov, 1951 

 Host: Physeter catodon - sperm whale. 

 Location: Placenta. 

 Locality: California. 

 Recorded by: Rice (1963). 



Porrocaecum sp. 



Host: Zalophus calif ornianus - California sea 



lion. 

 Location: Stomach. 

 Locality: California (San Diego Zoo). 

 Recorded by: Herman (1942). 

 Remarks: This species is undoubtedly a 



Terranova, likely T. decipiens. 



Stenurus minor (Kiihn, 1829) Baylis and 

 Daubney, 1925 

 Syns.: Stenurus phocoenae Dougherty, 1943. 

 Stenurus vagans (Eschricht, 1841) 

 Dougherty, 1943. 



Hosts: Phocoena phocoena - harbour porpoise; 

 Phocoenoides dalli - Dall porpoise. 



Locations: Lungs and head sinuses. 



Locality: California. 



Recorded by: Dougherty (1943a, c); John- 

 ston and Ridgway (1969). 



Remarks: Dougherty (1943a, c) argued that 

 the name minor was not available for this 

 nematode and proposed for it first the new 

 name phocoenae and later vagans. His views 

 seem not to have been generally accepted.
