本文根据形态学和古生物学证据评估了关系，并提出了一个进化方案来解释现存的苍白物种目前的分布。该科可分为 2 个组[长划线] Silentes 和 Stridentes，并且在每个组内，几个形态特征的平行趋势是明显的。与这些形态趋势相一致的是从深海到沿海水域的栖息地趋势；考虑这些条件下的适应性优势。最温暖最浅的地区由于栖息地的多样性而包含最多的物种，但这些物种在不断变化的总体环境中是最脆弱的。这些化石表明过去的辐射曾进入浅水区，但没有表明幸存的种群。幸存的祖先血统可能由深水居民代表。对回文属的深度和纬度分布进行分析表明，属的空间分布很少重叠；每个属似乎都有一组单独的深度和纬度参数。在西南印度洋，每个回纹藻属都有 1 个物种，大概是因为整个区域为这些属提供了所有单独的栖息地。有两种分布模式：环极分布和环赤道分布。 Puerulus（一种深水环赤道属）物种似乎与海洋盆地有关。最近进化的回虫属（Panulirus）的推测发生在更新世期间，4 个物种组可能反映了 4 个主要的冰川期。间冰期使中上层幼虫得以在赤道地区的大洋间扩散；在冰期期间，种群被物理屏障和更明确的现行系统隔离。许多海洋生物的深海区域是原始区域。辐射既向上进入浅水区，又向下进入更深的深海区域。
This paper evaluates relationships in the light of morphological and palaeontologlcal evidence and proposes an evolutionary scheme which accounts for the present distribution of extant pallnurld species. The family is divisible into 2 groups [long dash] Silentes and Stridentes-and within each a parallel trend in several morphological features is apparent. Coincident with these morphological trends is a habitat trend from bathyal to littoral waters; adaptive advantage under these conditions are considered. The warmest shallowest regions contain the most species because of the greater diversity of habitat but these species are the most vulnerable in a changing total environment. The fossils indicate past radiations into shallow water but not the surviving stock. The surviving ancestral line may be represented by the deeper water inhabitants. An analysis of depth and latitude distributions of the palinurld genera shows that the spatial distributions of the genera rarely overlap; each genus appears to have a separate set of depth and latitude parameters. In the southwest Indian Ocean 1 species of every palinurld genus is represented, presumably because the total region provides all the separate habitats for these genera. There are 2 patterns of distribution, a circumpolar and a cireumequatorial pattern. The species of Puerulus (a deep water circumequatorial genus) appear to be associated with oceanic basins. Speclation within the most recently evolved palinurld genus (Panulirus) has occurred during the Pleistocene and the 4 species groups probably reflect 4 major glaciatlon periods. Interglacials allowed equatorial inter-ocean dispersal of the pelagic larvae; during glacials, stocks were isolated by physical barriers and more defined current systems. The bathyal region for many marine organisms is the original region. Radiations have proceeded both up into shallow water and down into the deeper abyssal regions.
