novaehollandiae, hence it is under this host that the para- 

 sites should in future be placed. Puhrmann 1 has suggested 

 that Taenia novaehollandiae may be Dioicocestus. I prefer 

 to leave it as T. novaehollandiae until KreftVs types shall 



The name Taenia paradoxa is preoccupied having been 

 used by Rudolphi in 1809 for a cestode infesting species of 

 Scolopax, Chavadriiis, ;i n < I ( iallinatjo. Kudolphi's parasite 

 (= Choanolaenia paradoxa, K'ud.) is i|iiite distinct from 

 Krefft's species, which, like his T.iiocaeliollaiidioe, possesses 

 doubled genitalia in each segment, a fact not mentioned by 

 Kreff t in regard to his T. paradoxa. The types are so badly 

 preserved that it is diflicidt to say whether T. -paradoxa 

 andT. novaehollandiae are distinct, and accordingly I have 

 refrained from re-naming T. paradoxa, Kxefft, until I have 

 made out the anatomy of both species. 



Many parasites have been described from L. cristata 

 from other parts of the world, but not from Australia. 



Krefft does not give a definite locality for most of his

This parasite was obtained from the stomach of an 



Antarctic penguin. Baird does not mention any scientific 



name for the host. Krefft" merely quoted Baird's reference. 



Diesing 3 placed the parasite under Aptenodtites sp. Lin-
