Besides the avicularia, the polyzoa possess curious organs called vibracula.

除了鸟嘴骨外， 多栖动物还拥有被称为振动骨的奇怪器官。

But, as far as structure is concerned, I can see no similarity between tridactyle pedicellariae and avicularia.

但是，就结构而言， 我看不出 tridactyle pedicellariae 和 avicularia 之间没有相似之处。

Some species are provided with avicularia and vibracula, some with avicularia alone and a few with vibracula alone.

一些物种具有鸟骨和振动体， 一些仅具有鸟骨体， 少数仅具有振动体。

Certain compound animals, or zoophytes, as they have been termed, namely the Polyzoa, are provided with curious organs called avicularia.

某些复合动物， 或被称为植虫的动物， 即 Polyzoa， 具有称为鸟嘴体的奇特器官。

As the chelae of Crustaceans resemble in some degree the avicularia of Polyzoa, both serving as pincers, it may be worth while to show that with the former a long series of serviceable gradations still exists.

由于甲壳动物的螯在某种程度上类似于多生动物的鸟骨，两者都起着钳子的作用， 因此可能值得证明前者还有一长串可用的等级。

The avicularia, like the vibracula, probably serve for defence, but they also catch and kill small living animals, which, it is believed, are afterwards swept by the currents within reach of the tentacula of the zooids.

avicularia 和 vibracula 一样， 可能起到防御作用， 但它们也捕捉并杀死活体小动物，据信，这些动物随后会在类动物的触手可触及的范围内被水流冲走。

In the avicularia and vibracula of the Polyzoa we have organs widely different in appearance developed from the same source; and with the vibracula we can understand how the successive gradations might have been of service.

在 Polyzoa 的鸟骨和颤骨中， 我们发现同一来源的器官在外观上大不相同；有了颤音，我们就可以理解连续的层次是如何发挥作用的。

Thus, with the avicularia of several species of Lepralia, the movable mandible is so much produced and is so like a bristle that the presence of the upper or fixed beak alone serves to determine its avicularian nature.

因此，对于 Lepralia 的几种物种的鸟骨， 可移动的下颌骨产生得如此多， 并且非常像刚毛， 以至于仅存在上喙或固定喙就可以确定其鸟骨性质。
