Abstract
  1. Bile salts of the coelacanth Latimeria chalumnae Smith (five specimens) and of the three living genera of lungfish (Dipnoi) were examined as completely as possible and compared. 2. The small 'bile acid' fractions include no more than traces of well-known C27 or C24 acids (free or conjugated) and the functioning bile salts must be regarded as alcohol sulphates. 3. Comparison of the alcohols suggest that (a) Latimeria stands biochemically outside the animal group which includes the Dipnoi, (b) Protopterus and Lepidosiren are more closely related to one another than either is to Neoceratodus, (c) all four primitive osteiychtheans have some amphibian affinities, (d) there are affinities between Latimeria and Dipnoi and ostariophysan families (especially Cyprinidae and Catostomidae) and (e) there are biochemical links between Dipnoi and lampreys.
摘要
  1. 对腔棘鱼拉蒂迈鱼(5个标本)以及三种现存肺鱼目(肉鳍鱼纲)鱼类的胆汁盐进行了尽可能全面的检测与比较。2. 少量的“胆汁酸”组分中仅含有痕量的知名C27或C24酸(游离或结合形式),且起作用的胆汁盐必须视为醇硫酸盐。3. 对醇类的比较表明:(a) 从生物化学角度看,拉蒂迈鱼处于包括肺鱼目的动物类群之外;(b) 非洲肺鱼和美洲肺鱼彼此之间的亲缘关系比它们与澳洲肺鱼的关系更为密切;(c) 所有这四种原始硬骨鱼都具有一些与两栖动物的亲缘关系;(d) 拉蒂迈鱼与肺鱼目及骨鳔总目鱼类(特别是鲤科和胭脂鱼科)之间存在亲缘关系;(e) 肺鱼目与七鳃鳗之间存在生物化学联系。
