This study reports the occurrence of annulate lamellae in the rudimentary photoreceptor cells of the pineal organ of a tinamid bird Crypturellus parvirostris. The annulate lamellae observed in these cells are located in the cell body and are comprised of 1 to 8 parallel lamellae, symmetrically aligned and regularly spaced. Each lamella consists of pairs of parallel membranes interrupted by regularly spaced pores or annuli. These observations are discussed and compared with the structure and distribution of these organelles referred in the literature.
本研究报告了在一种小䴙䴘科鸟类——小喙凤头䴙䴘松果体的原始光感受器细胞中出现环状片层的情况。在这些细胞中观察到的环状片层位于细胞体中，由1至8个平行片层组成，对称排列且间隔规则。每个片层由成对的平行膜组成，这些膜被规则间隔的小孔或环中断。本文对这些观察结果进行了讨论，并与文献中提及的这些细胞器的结构和分布进行了比较。
