四鳃易拉鱼的卵泡营养发育包括六个无肢期和一个鲤期。尽管有脂肪增生，浮游nauplius有完整的骨骼肌组织，部分与腹侧内骨骼相关。腕足肌肉组织在腕足的前五个阶段保持不变。肌肉组织的变化开始发生在第六期，这是第六次换毛时塞浦路斯肌肉组织变化的初步阶段。在这一转变过程中，一些腓骨肌被组织，一些腓骨肌作为新的发育而产生，一些肌肉由腓骨肌转变为腓骨肌。详细介绍了这些变化。本文比较了四角棘猴从无节节到节节节的肌肉发育模式与半balbalanus balanoides无节节节-节节节蜕皮过程中更为极端的肌肉组织溶解和替换。还比较了鲤的肌肉组织与根头蕨Lernaeodiscus porcellanae的肌肉组织。尽管有脂肪萎缩，但四角鼠仍保留了相对普遍的胸跖肌和塞浦路斯肌的排列，并从一种肌肉到另一种肌肉的普遍过渡。讨论了晚期胸胸动物无钩-塞浦路斯脱毛处全肌置换的演变。
The lecithotrophic development of Ibla quadrivalvis comprises six naupliar stages and a cypris stage. Despite lecithotrophy, the planktonic nauplius has a complete skeletal musculature, associated in part with a ventral endoskeleton. The naupliar musculature remains unchanged for the first five naupliar stages. Modifications of the musculature begin to occur in stage VI, preliminary to the change at the sixth moult to the musculature of the cyprid. In this transition, some naupliar muscles are histolysed, some cypris muscles arise as new developments and some muscles are transformed from naupliar muscles to cypris muscles. Details are given of these changes. The pattern of muscle development during the change from nauplius to cyprid in I. quadrivalvis is compared with the more extreme histolysis and replacement of the musculature during the nauplius-cyprid moult of Semibalanus balanoides. The cypris musculature is also compared with that of the rhizocephalan Lernaeodiscus porcellanae. In spite of lecithotrophy, I. quadrivalvis retains a relatively generalized arrangement of thoracican naupliar muscles and cypris muscles and a generalized transition from one to the other. The evolution of total muscle replacement at the nauplius-cyprid moult in advanced thoracicans is discussed.
