The main morphological traits of Fossaria cubensis and Pseudosuccinea columella, the two intermediate hosts of fascioliasis in Cuba, were studied. Differences may be seen regarding some aspects of the external morphology, as well as in the internal morphology, mainly in the reproductive system. The radular teeth have differences which are rather intangible, not allowing for their taxonomic isolation on the basis of this criterion alone. These studies suggest to take into account several criteria in order to determine the taxonomic position of each species.
对古巴片形吸虫病的两个中间宿主古巴小土蜗（Fossaria cubensis）和柱形假琥珀螺（Pseudosuccinea columella）的主要形态特征进行了研究。在外部形态的某些方面以及内部形态，主要是生殖系统方面，可以看到差异。齿舌齿存在一些难以捉摸的差异，仅基于这一标准无法对其进行分类隔离。这些研究表明，为了确定每个物种的分类地位，需要考虑几个标准。
