摘要
摘要:本部分对英国白垩纪棘足类(spatangoid family microsteridae)的棘足类进行了系统的修订。本文描述并说明了属(Roweaster 11 .)和属(Micraster)两属的18种，并提供了种的检索表。其中六种以前没有在不列颠群岛记录过，其中一种是新发现的。为这些物种提供了新的镀层图。此外，还描述了一种cassiduoid, Archiacia sp.和一种新的全小行星Pseudananchys speetonensis sp. nov.。给出了222种英国白垩纪棘足类的地层和地理分布概况。
ABSTRACT This part completes the systematic revision of the British Cretaceous echinoids with a review of the species belonging to the spatangoid family Micrasteridae. Eighteen species belonging to two genera, Roweaster nov. and Micraster, are described and illustrated and a key to the species is provided. Six of these species have not previously been recorded from the British Isles and one species, Micraster (Gibbaster) norfolkensis, is new. New plating diagrams are provided for these species. In addition a cassiduloid, Archiacia sp., and a new holasteroid, Pseudananchys speetonensis sp. nov., are described. Tables summarizing the stratigraphical and geographical distribution of all 222 British Cretaceous echinoids are provided.
