But my work had hardly been published, when a skilful palaeontologist, M. Bosquet, sent me a drawing of a perfect specimen of an unmistakable sessile cirripede, which he had himself extracted from the chalk of Belgium.

但我的作品几乎没有发表，一位​​技艺高超的古生物学家 M. Bosquet，给我寄来了一幅完美的无柄蔓足动物标本的图画，这是他本人从比利时的粉笔中提取的。

And, as if to make the case as striking as possible, this cirripede was a Chthamalus, a very common, large, and ubiquitous genus, of which not one species has as yet been found even in any tertiary stratum.

而且，好像为了使这个案例尽可能引人注目，这种花螈是 Chthamalus，一种非常常见的、大且普遍存在的属，即使在任何第三层中也没有一个物种被发现.

Cirripedes long appeared to me to present, under this point of view, a case of great difficulty; but I have been enabled, by a fortunate chance, to prove that two individuals, though both are self-fertilising hermaphrodites, do sometimes cross.

长期以来，在我看来，在这种观点下， 蜈蚣似乎是一个非常困难的案例；但幸运的是， 我得以证明两个个体， 尽管都是自花授精的雌雄同体， 有时确实会杂交。
