描述和扫描电子显微镜下的壳，原贝壳，齿舌，和外部解剖提供了四种cocculiniform帽贝从深海深处的开曼群岛和波多黎各海沟。其中，一个代表一个新的属和种，Macleaniella moskalevi（球虫科），特有的波多黎各海沟。另一个，Amphiplica plutonica（Pseudococculinidae），代表了一个来自开曼海沟的全球分布的深海属的新种。剩下的两个物种，Fedikovella caymanensis（Cocculinidae）和Caymanabyssia spina（Pseudococculinidae），都来自开曼海沟，也是它们各自属的模式种，它们的原始描述只包含了部分贝壳的复制插图，以及孤立的齿舌齿行的线条图。这四个物种，每一个显然是特有的各自的战壕，代表了最深的记录，在大西洋收集的软体动物。
Descriptions and scanning electron micrographs of the shell, protoconch, radula, and gross external anatomy are provided for four species of cocculiniform limpets collected from hadal depths of the Cayman and Puerto Rico trenches. Of these, one represents a new genus and species, Macleaniella moskalevi (Cocculinidae), endemic to the Puerto Rico Trench. Another, Amphiplica plutonica (Pseudococculinidae), represents a new species from the Cayman Trench of a globally distributed abyssal genus. The original descriptions of the remaining two species, Fedikovella caymanensis (Cocculinidae) and Caymanabyssia spina (Pseudococculinidae), both from the Cayman Trench and type species of their respective genera, contained only poorly reproduced illustrations of portions of the shells, and line drawings of isolated rows of radular teeth. These four species, each apparently endemic to their respective trenches, represent the deepest records of molluscs collected in the Atlantic Ocean.
