对多翅目幼虫标本的软骨头骨进行了重新描述，并首次发现了早期标本。以下结构的发育以前没有在多翅目鱼中被描述过：1.首先由前突形成的外侧连合，然后是腭后突起。2.边缘带，形成明显的软骨。3.内脏弓的发育和第一、第二下支及颈支的暂时融合。然后将这一发展与Scyllium、Amia、鳞骨、鲟鱼和硬骨鱼的发展进行简要比较；在它和Amia之间显示出强烈的相似之处。因此，古德里奇的观点得到了额外的支持。
The chondrocranium of the existing specimens of the larval Polypterus have been redescribed, and the earlier specimens figured for the first time. The development of the following structures have not been described previously in Polypterus: 1. The lateral commissure which forms first from the prootic and then the post-palatine process. 2. The taenia marginales, which arise as distinct cartilages. 3. The development of the visceral arches and the temporary fusion of the first and second hypobranchials and ceratobranchials. This development is then briefly compared with those of Scyllium, Amia, Lepidosteus, Acipenser, and Teleosts; a strong likeness being shown between it and that of Amia. The view of Goodrich is thus afforded additional support.
