从丹麦和德国北部的白色白垩岩中记述了12种自由生活的唇口苔藓虫新种：LUNULITS PUSCRATACEA，L.microstoma，L.Vespertilo，L.conulus，L.patens，L.immensa，L.foveolata，Pavolunulites parva，P.schmidi，P.insolita，P.moenensis，P.Danica。11个物种仅限于马斯特里赫特山脉，而一个物种也分布在上坎帕尼亚地层。简要讨论了白垩纪中新月球石和白云母属的系统地位。
Twelve new species of free-living cheilostome bryozoans are described from the white chalk of Denmark and northern Germany: Lunulites pseudocretacea, L. microstoma, L. vespertilio, L. conulus, L. patens, L. immensa, L.foveolata, Pavolunulites parva, P. schmidi, P. insolita, P. moenensis, P. danica. Eleven species are restricted to the Maastrichtian, while a single species also range down into Upper Campanian strata. The systematic status of the genera Lunulites and Pavolunulites in the Cretaceous is briefly discussed.
