四、泰勒和贝利斯在提请注意第二次和第三次会议时指出，他们的观察是独立进行的，对这项工作并不知情，他们证实了这一点。他们指出，c.ElvaeMiller，1923年，可能与C.ocellata，La Valette，1855在命名上相同，因此必须让位于C.ocellata，La Valette，1855。他们发现尾蚴具有如此强烈的负向地性，以至于它们不能通过离心式沉淀得到令人满意的浓缩。这一特征具有趋光性，表明某些表面游动的动物是合适的最终宿主。这种宿主没有被发现，但尾蚴与波罗尼亚毕尔哈齐氏菌非常相似，后者成年后生活在鸭子的肠系膜静脉中。在里斯小姐的画中，尾蚴的形态得到了精美的说明。尾蚴在投放尾巴后穿透小鼠皮肤，在人类皮肤上产生持续数周的地面瘙痒，但没有爬行爆发。另一种形式，“尾巴X”，不会惹恼人类，而是进入小鱼并到达光学晶状体。C.L.
iv. Taylor and Baylis, while drawing attention to ii and iii, note that their observations were made independently and without knowledge of this work, and that they confirm it. They point out thatC. elvaeMiller, 1923, is probably identical with, and so must give way in nomenclature to, C.ocellata, La Valette, 1855. They found that the cercariae had so strong a negative geotropism that they could not satisfactorily be concentrated by centrifugal precipitation. This character, with that of phototropism, point to some surface-swimming animal as the proper definitive host. This host was not discovered, but the cercaria closely resemblesBilharziella polonicawhich, as adult, inhabits the mesenteric veins of ducks. The morphology of the cercaria is beautifully illustrated in drawings by Miss REES. Cercariae penetrated mouse skin after casting their tails, and in human skin produced a ground itch persisting for weeks, but no creeping eruption. The other form, " Cercaria X, " does not annoy man, but enters small fish and reaches the optic lens. C. L.
