To determine whether Monterey Botryllus and Woods Hole Botryllus are the same species, comparisons were made of their morphology, biology, and colony specificity. In addition, matings were carried out to ascertain whether fertile [Monterey x Woods Hole] F1 progeny could be obtained. The morphology and biology of Botryllus colonies from Monterey and from Woods Hole are very similar, and fertile F1 progeny were obtained from interpopulation crosses. Therefore, we conclude that Monterey and Woods Hole Botryllus belong to the same species. However, slight differences were observed in the allorecognition reactions (colony specificity) of these two populations. Although there are some inconsistencies among the descriptions of Botryllus schlosseri and further extensive studies of Botryllus taxonomy are needed, our data indicate that Botryllus from Monterey and from Woods Hole may be designated contingently as B. schlosseri.
为了确定蒙特雷柄海鞘和伍兹霍尔柄海鞘是否为同一物种，对它们的形态学、生物学和群体特异性进行了比较。此外，进行了交配实验以确定是否能够获得可育的[蒙特雷×伍兹霍尔]F1后代。来自蒙特雷和伍兹霍尔的柄海鞘群体的形态学和生物学非常相似，并且从群体间杂交中获得了可育的F1后代。因此，我们得出结论，蒙特雷柄海鞘和伍兹霍尔柄海鞘属于同一物种。然而，在这两个群体的异体识别反应（群体特异性）中观察到了细微差异。尽管在施氏柄海鞘的描述之间存在一些不一致之处，并且需要对柄海鞘分类学进行进一步广泛的研究，但我们的数据表明，来自蒙特雷和伍兹霍尔的柄海鞘可能暂时被指定为施氏柄海鞘。
