Localities: Alaska; British Columbia; Wash- 

 ington. 

 Recorded by: Stiles and Hassall (1899); 

 Scheffer and Slipp (1944) ; Scheffer (1945); 

 Fisher (1952); Rausch (1953); Schiller 

 (1954); Margolis (1956); Neiland (1961); 

 Kenyon (1962,1969); Keyes (1965); John- 

 son et al. (1966). 

 Remarks: The nomenclatural combination 

 Terranova decipiens apparently was first 

 published by either Mozgovoy (1951) or 

 Skrjabin et al. (1951). According to in- 

 formation received from colleagues in the 

 USSR it is not known which of these two 

 publications was issued first. The cor- 

 rected proofs of Mozgovoy (1951) and 

 Skrjabin et al. (1951) were returned to 

 the publisher on July 20, 1951, and June 

 4, 1951 (the "podpisano k pechati" dates 

 shown on these publications), respectively, 

 but it does not follow that the first to be 

 returned was necessarily the first to be 

 published. In view of this uncertainty it 

 would seem just to consider Mozgovoy as the 

 author of the combination T. decipiens be- 

 cause apparently he used this name in a 

 thesis written in 1949 and, as a co-author of 

 Skrjabin et al. (1951), he was responsible 

 for the section on Ascaridata in that book. 

 Authors who have been erroneously re- 

 garded as the originators of the combina- 

 tion T. decipiens are Baylis (1916), Johns- 

 ton and Mawson (1945), and Mozgovoy 

 (1953) (see Mozgovoy, 1951, 1953; Skrjabin 

 et al., 1951; Margolis, 1956; Myers, 1959). 



Trichinella spiralis (Owen, 1835) Railliet, 1895 



(larva) 

 Host: Odobenus rosmarus - walrus; Phoca 



sp. 

 Location: Muscle. 

 Locality: Alaska. 

 Recorded by: Rausch et al. (1956); Fay 



(1960). 

 Remarks: Rausch et al. (1956) also reported 



Trichinella spiralis larvae from Erignathus 



barbatus and Delphinapterus leucas in Arctic 



Alaska. 



Uncinaria sp. 



Host: Zalophus calif ornianus - California sea 

 lion. 



Location: Intestine. 



Locality: California. 



Recorded by: Dailey and Hill (1970). 



Remarks: Dailey and Hill (1970) considered 

 their specimens to be identical with those 

 tentatively identified by Baylis (1933) from 

 a sea lion from the San Francisco Bay area 

 as Uncinaria hamiltoni (see below). 



Uncinaria hamiltoni Baylis, 1933 



Host: (?) Eumetopias jubatus - Steller sea 

 lion. 



Location: Intestine. 



Locality: California. 



Recorded by: Baylis (1933, 1947). 



Remarks: Baylis doubtfully assigned materi- 

 al obtained "from a sea lion at Palo Alto, San 

 Francisco Bay, California" to Uncinaria 

 hamiltoni although the measurements did not 

 agree with the material collected from Otaria 

 byronia. Baylis assumed the sea lion was 

 Eumetopias jubatus inasmuch as it is the 

 "commoner of the two species of sea lions 

 occurring in the region of San Francisco 

 Bay." Accepting the validity of Dochmoides 

 Cameron, 1924 as a replacement for Unci- 

 naria Frolich, 1789, Wolfgang (1956) trans- 

 ferred U. hamiltoni to Dochmoides. 



Uncinaria lucasi Stiles, 1901 



Syn.: Uncinaria sp. of Stiles and Hassall, 

 1899. 

 Hosts: Callorhinus ursinus - northern fur 



seal; Eumetopias jubatus - Steller sea lion. 

 Location: Intestine.
