i'<i "TERRA NOVA" EXPEDITION. 



Th.' Staff seized the opportunity afforded l>y a day's stay to make collections of the 

 fishes, hirds and crabs. The parasites obtained were : 



('/) Three species of Cestode from the Trinidad petrels ((Extrflntn <inninjoit'nui<i 



and (E. trin it, it !.<} : 



(/>) One species of Cestode from a Frigate bird (Fregata aquila or F. artel] ; 

 (c) Two larval Tt'fntr/it/itr/iHN from a small shark (('tircluu'i<tx sp.) ; 

 ('/) Specimens of an Oligochaete, extracted from Laud - crabs (G<'<-ar<:/nux 



/,/,/oxf oin,/, H.M.-E.). 



The stay of the ship was so brief that the material collected is in no way indicative 

 of the extent of the parasitic Fauna of the Island. 



S. Trinidad would probably afford a rich field for the further investigation of 

 parasites, as many hosts, especially birds and fishes, abound and are easily procurable. 



Teiii/ii'nif,' Zoin'. On the 3rd October, 1910, when the "Terra Nova " was in 

 Lat. 42 17' 8., Long. 111 18' E. (Stat. 156), a Great Grey Shearwater (Pufliiut* <-hh>r,'i<*) 

 was caught, and provided one species of Cestode, Trtmhotlir'niN heteroclitus. On the 6th 

 October. 1910, when the ship was in Lat. 41 4f>' S., Long. 121 39' E. (Stat, 159), 

 a Sooty Albatros or Ilutton's Albatros (Phcebetria palpebrata) was caught. This 

 provided two species of Cestodes, one unfortunately only in fragments and without 

 a head. These proved to be : 



(a) Tetrctbothrius nelsoni, n. sp. 

 (/>) Unrecognizable. 



The following parasites were collected at the Bay of Islands in New Zealand, in 

 Lat, 35 15' S., Long. 174 10' E. (Stat, 149), by Mr. D. G. Lillie, Biologist to the 

 Expedition, when he was on a whaling cruise with a Norwegian ship : 



(a) From a Humpback Whale (Afci/ii/>terii) numerous specimens of a Filariid 

 Nematocle, Crassicauda <-i;ixxi<;nnl<i (Creplin), from the renal tubules. 



(/') From a. Rorqual (Balaenoptera />/vw//X Lesson) one specimen of a Cestode 

 and some pretty examples of the curious Pomporhynchus turbinella. 



(c) From a Shark (Mustelus antarctwus) a Nematode, and 



(d) From a Barracouta (Lepidopus caudatus) some larval Nematodes encysted in 



the caecum, and with them a larval Tetrarhynchus. 



In Lat, 52 20' S., Long. 167 30' E. (Stat, 165), off the Campbell Islands : 

 (c) A Mollymauk (l>ioni<'il<'<i ni<'/<nn>]>/n'i/K) was caught and provided some 



Nematodes. 



Antni-rtir Ziiiie. The larger portion of the collection of parasitic worms was made, 

 however, in the vicinity of Cape Evans in Lat. 77' J 38' S., Long. 16(1 24' E. (Stations 

 312, 326, etc.), during the winter months of 1911. In the succeeding year conditions 

 were exceedingly unfavourable, and the collection could <>nlv be added to very slightly.
