" Adapted from C. E. Bills in W. H. SebreU, Jr., and R. S. Harris, The Vitamins, Vol. 

 II, Academic Press, Inc., New York, 1954, pp. 165, 166. The nomenclature for the spe- 

 cies is that of Jordan et al.^'^" rather than that chiefly employed in this and other volumes 

 of The Lipids, which is largely based upon the report entitled A List of Common and 

 Scientific Names of Better-Known Fishes of the United States and Canada, which appears 

 as Transactions of American Fisheries Society, 75, Special Publication No. 1, 355-397, 

 Ann Arbor, Michigan, 1948, and upon the manuscript List of "Fishes of California" 

 prepared by C. L. Hobbs and W. I. Follett, California Acad. Sciences (San Francisco) 

 1956. This may account for some discrepancies in systematic nomenclature between 

 this table and the te.xt. 



noted its presence in the commercial menhaden oil, which is a body oil. 

 The liver and body oils of a given species were generally found to be quite 

 similar, but the vitamin concentration is invariably higher in the liver oil. 

 Thus, in the case of the tuna, the liver oil may be several thousand times 

 richer in vitamin D than the body oil. Bills^''* gives the following figures 

 for the vitamin D content of fish mesentery oils: "black horse" or blue 

 sucker (Cydeptus elongatus), 400 I.U./g. ; golden perch or fresh water drum 

 (Aplodinotus grunniens), 11 I.U./g.; big-mouth buffalo fish (Ictiohus 

 (Megastomatohns) cyprinella), 10 I.U./g.; and spotted channel catfish 

 (Idalurus punctatus), 5 I.U./g. Values for the vitamin D in the oil from 

 the entire bodies of the fishes include the following: herring {Clupea haren- 

 gus), 100 I.U./g.; California sardine or pilchard (Sardinops caerulca), 80
