The species of the genus Verrill, 1868 from the shallow waters of the tropical eastern Pacific were mainly described from 1846 to 1870. Very few contributions were published subsequently. Recently, the genus was revisited with the addition of two new species. However, a comprehensive generic study is still missing for the eastern Pacific. is characterised by having axes cores without mineralisation, mainly coarse irregular spindles and thorny, leafy or tuberculate clubs coenenchymal sclerites and the anthocodial armature with distinct collaret and points arrangements. Herein a taxonomic revision of the genus is presented based on type material which was morphologically analysed and illustrated using optical and scanning electron microscopy. Comparative character tables are provided for comparison among species in the genus, along with a taxonomic key. Moreover, the taxonomic status of each species was analysed. The genus comprises six valid species and two varieties, and three lectotypes and a new combination are proposed to establish the taxonomic status of these species.
1868年命名的Verrill属物种来自热带东太平洋的浅水区，主要是在1846年至1870年期间被描述的。此后发表的相关文献极少。最近，随着两个新物种的加入，该属被重新研究。然而，东太平洋地区仍缺乏对该属的全面研究。其特征是轴芯无矿化，主要为粗大不规则的纺锤体以及多刺、叶状或瘤状的群体骨针，且蒴萼具独特的项圈和刺点排列。本文基于模式标本对该属进行分类修订，利用光学显微镜和扫描电子显微镜对其形态进行了分析和绘图。提供了比较特征表以便该属内各物种之间进行比较，同时还给出了分类检索表。此外，还分析了每个物种的分类地位。该属包括六个有效物种和两个变种，并提出了三个选模式以及一个新组合来确定这些物种的分类地位。
