Parona from the intestine of Globicephalus mêlas Traill. Thus this 

 species is confined to the family Delphinidae. 



Globicephalus mêlas which is gregarious and said to be of a mild 

 disposition « feeds principally on Cephalopods ». 



3. — Echinorhynchus porrigens Rudolphi. — Westrumb records 

 this from the small intestine of Balsena rostrata which is probably 

 either Hyperoodon rostratus Mùll. or Balœnoptera rostrata Fabr. 

 Professor Collett now adds the new host Megaptera boops L. 



Hyperoodon rostratus eats Cephalopods, sometimes Herrings and 

 one observer records « small Crustacea ». Balœnoptera rostrata eats 

 différend kinds of Fish. Megaptera boops eats the « Capelin » Mallotus 

 villosus, Herrings, and Boreophausia inermis. 



4. — Echinorhynchus turbinella Diesing. — Synonyms : E. pellu- 

 cidus F. S. Leuckart; E. ruber Collett. — Diesing describes this 

 species from the intestine of Delphinus hyperoodon, which is cata- 

 logued by Sir William Flower as Hyperoodon rostratus Mùll. The 

 spécimens found by Collett and described by him as E. ruber, were 

 from the intestines of Balaenoptera borealis Less. 



Certain spécimens of E. turbinella in my collection were taken 

 from Sibbald's Rorqual or the Blue Whale, Balœnoptera Sibbaldi 

 Gray by Professor Collett, and Borgstrôm has added a new host in 

 the Common Rorqual or Fin Whale, Balaenoptera musculus L. The 

 E. pellucidus of S. F. Leuckart which I also believe to be identical 

 with the above named species, species, came from the intestine of 

 the Common Dolphin Delphinus delphis L. 



The food of Hyperoodon rostratus is mentioned above. Balœnoptera 

 borealis eats Calamus fmmarchicus and Boreophausia inermis and 

 never feeds on Fish. B. musculus eats Fish, feasting on shoals of 

 Herrings. The food of B. Sibbaldi is mentioned above. The Dolphin 

 chiefly eats Fish.
