Dipetalonema odendhali — Cont. 



Remarks: Perry (1967) noted that Ander- 

 son's (1959) specimens from the testicular 

 sheath, subcutaneous tissue, and upper colon 

 of northern fur seals from Alaska, which the 

 latter author doubtfully referred to Dipetalo- 

 nema spirocauda, may belong- to D. odendhali. 



Dipetalonema spirocauda (Leidy, 1858) Ander- 

 son, 1959 



Hosts: ( ?) Callorhinus ursinus - northern fur 

 seal; Phoca vitulina richardi - harbour seal. 



Location: Heart. 



Localities: (?) Alaska; California (captive 

 harbour seals). 



Recorded by: Anderson (1959); Taylor et al. 

 (1961); Keyes (1965). 



Remarks: Like Anderson's (1959) specimens 

 from the northern fur seal from Alaska (see 

 Dipetalonema odendhali) , the specimens re- 

 ported by Keyes (1965) from subcutaneous 

 tissues of the same host species from the 

 same locality may be D. odendhali. D. spi- 

 rocauda and D. odendhali apparently differ 

 in their sites of infection, the former being 

 found in the heart and main arteries and 

 the latter mainly in connective tissues (see 

 Perry, 1967). For synonymy and a review 

 of the taxonomy of D. spirocauda, see An- 

 derson (1959). 



Dirofilaria immitis (Leidy, 1856) Ralliet and 

 Henry, 1911 

 Syns.: Dirofilaria spirocauda (Leidy, 1858) 

 sub judice Faust, 1937. 

 Dirofilaria fausti Skrjabin and Shi- 

 khobalova, 1948. 



Host: Zalophus calif ornianus - California sea 

 lion. 



Location: Heart. 



Locality: Zoological Garden, New Orleans, 

 La. (animal captured at Sea Cliffs, Calif.). 



Recorded by: Faust (1937). 



Remarks: Faust (1937) did not definitely de- 

 cide on the specific identity of his specimens. 

 He recognized that they were morphologi- 

 cally indistinguishable from the type material 

 of Dirofilaria immitis; however, he associ- 

 ated them provisionally with Filaria spiro- 

 cauda Leidy, 1958 (the types of which were 

 not available for restudy) under the name 



Dirofilaria spirocauda (sub judice) . Skrja- 

 bin and Shikhobalova (1948) named a new 

 species, D. fausti, for Faust's material. 

 Faust's specimens are now accepted as D. 

 immitis, and Filaria spirocauda is regarded 

 as a distinct species, Dipetalonema spiro- 

 cauda (see Anderson, 1959). Perry (1967) 

 expressed doubt that D. immitis occurs en- 

 zootically in California sea lions and implied 

 that the sea lion examined by Faust could 

 have acquired its infection in New Orleans, 

 where D. immitis is enzootic.
