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

一般认为翼手目的食虫蝙蝠和食虫目的树鼠在系统发育上很接近，因为它们在牙列类型、牙列和子宫结构上都很相似。通过对这两类哺乳动物的鞭毛虫区系的调查，得到了支持这一观点的新证据，即它们被某些常见的鞭毛虫寄生。这似乎意味着蝙蝠和地鼠都会捕食同一种昆虫，因为这种昆虫需要作为绦虫发育的中间宿主。同样的昆虫被吃掉表明它们的食物习性非常相似，相同种类的绦虫通常可以寄生在它们身上，这被认为是蝙蝠与地鼠在系统发育上接近的证据。

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.
