On the systematic connection of Chiroptera and Insectivora with special reference to their cestode fauna.

一般认为翼翅目食虫蝙蝠与食虫目鼩鼱在齿列类型、齿列、子宫结构等方面具有相似性，在系统发育上是相近的。目前对这两类哺乳动物的寄生区系的调查得到了支持这一观点的新证据，即它们是由某些常见的寄生种寄生的。这似乎意味着同一种昆虫是蝙蝠和鼩鼱的猎物，因为这类昆虫是寄生蜂发育的中间寄主。蝙蝠吃同一种昆虫，说明它们的饮食习惯非常相似，而且同一种寄生蜂通常可以寄生在它们身上，这被认为是蝙蝠在系统发育上与鼩鼱接近的证据。

It is generally considered that the insectivorus bat of the order Chiroptera and the shrew of the order Insectivora are phylogenetically close to each other because of the similarity in the type of dentition, tooth-row, and the structure of uterus. A new evidence to support this view was gained by the present investigation of the cestode faunas of the two groups of mammals, that is, they are parasitized by certain common species of cestodes. This seems to mean that the same kind of insects are preyed upon by both bats and shrews, since such insects are need as inter- mediate hosts for the development of cestodes. That the same insects are eaten suggests taht their food habits are very similar, and that the same species of cestodes can normally parasitize them is regarded as a proof that the bat is phylogenetically close to the shrew.
