Synopsis Descriptions are offered of two foetal gorillas representative of developmental stages intermediate between those previously described by Duckworth (1904), Schultz (1927) and Deniker (1885). They are numbered accordingly II and IV and comparison made throughout with the other stages represented in the literature. Special attention has been paid to the ontogenetic changes occurring in the bodily form, and posture, cutaneous structures, cranial and skeletal development and in the disposition of the thoracic and abdominal viscera, much of which is previously known only in respect of Deniker's stage V.

Synopsis In a previous paper (Andrews and Westoll 1970) the postcranial skeleton of the best known rhipidistian, Eusthenopteron, was described, and its bearing on the origin of the tetrapod postcranial skeleton discussed. The postcranial remains of other Rhipidistia are now described as far as they are known, and comparisons are made with Eusthenopteron and other forms where relevant. Possible modes of function are considered in relation to the habitats in which these fishes may have lived. These studies have made it necessary to revise rhipidistian classification; the Family Rhizodontidae is re-defined and placed alone in a third Order of Rhipidistia (the Rhizodontida, alongside the better known Osteolepidida and Holoptychiida). Fresh insight has been gained into the following morphological problems: the composition of the osteolepid ring-like centrum, the origin of the tetrapod scapular blade and the diphyletic origin of the tetrapods.
在之前的一篇论文(Andrews and Westoll 1970)中，描述了最著名的鳍足动物真鳍龙的颅后骨骼，并讨论了它与四足动物颅后骨骼起源的关系。目前已知的其他里脊鱼的颅骨残骸已经被描述，并与真鳍龙和其他相关的形式进行了比较。可能的功能模式被考虑与这些鱼类可能生活的栖息地有关。这些研究表明，有必要修订海鞘分类;根齿虫科被重新定义，并被单独置于齿虫目的第三目(根齿虫目，与更知名的骨齿虫目和全齿虫目并列)。在以下形态学问题上获得了新的见解:骨脂环状椎体的组成，四足动物肩胛骨的起源和四足动物的双系起源。

Synopsis Bohemian specimens of the phacopacean trilobites Reedops cephalotes (Hawle and Corda,) R. sternbergi (Hawle and Corda) and R. bronni (Barrande) have very well preserved schizochroal eyes. The sizes and distribution patterns of the eye lenses were studied and in R. sternbergi and R. bronni the angular bearings of all the lenses were measured, giving the visual range of the whole eye. The internal anatomy of the eyes was also investigated, mainly from cut and polished sections. In many respects their morphology was comparable with that described previously in the Silurian and Devonian phacopaceans Phacops latifrons (Bronn) and Ananaspis communis (Barrande). The intralensar structures, however, are unlike those of P. latifrons and A. communis but bear a strong resemblance to the intralensar bowls of the Ordovician Zeliszkellinae, an early group believed to have been ancestral both to dalmanitaccan and post-Ordovician phacopacean stocks. A brief history of the evolution of schizochroal eyes is given, some distinctive evolutionary trends are noted and the relationship of the structural pattern in Reedops is discussed with reference to that in other Phacopina.
波西米亚的棘足纲三叶虫Reedops cephalotes (Hawle和Corda)， R. sternbergi (Hawle和Corda)和R. bronni (Barrande)的标本保存完好。研究了眼晶状体的大小和分布模式，并测量了sternbergi和R. bronni的所有晶状体的角方位，给出了整个眼睛的视觉范围。眼睛的内部解剖结构也进行了研究，主要是通过切割和抛光的部分。在许多方面，它们的形态与先前在志留纪和泥盆纪phacopacean (Bronn)和Ananaspis communis (Barrande)中描述的Phacops latifrons和Ananaspis communis相似。然而，囊内结构与P. latifrons和a . communis不同，但与奥陶系Zeliszkellinae的囊内碗非常相似，后者是一个早期群体，被认为是dalmanitaccan和后奥陶系phacopacean种群的祖先。本文简要介绍了分裂眼的进化历史，指出了一些独特的进化趋势，并讨论了芦苇的结构模式与其他植物的结构模式的关系。
