“中中新世加勒比区”一词用于指包括西大西洋和东太平洋沃茨的动物区系。表中列出了该省13个地方动物区系中特有种所占的百分比。一般来说，最大的动物群拥有最高比例的特有物种，但这种概括的显着例外是显而易见的。许多物种和属的不连续分布的例子，它们不是残遗，支持这样的结论，即大部分特有现象是明显的，而不是真实的。
The term "middle Miocene Caribbean province" is used for a faunal province that embraced both western Atlantic and eastern Pacific waters. The percentage of endemic species in 13 local faunas in that province is tabulated. In general the largest faunas have the highest percentage of endemic species, but notable exceptions to that generalization are apparent. Many examples of discontinuous distribution of species and genera, which are not relicts, support the conclusion that much of the endemisim is apparent rather than real.
