Osculocystis, a new scoliocystine cystoid, is characterized by reduced oral plates which form a tubercle; three pectinirhombs, B2:IL2, L2:R1, and L4:R4; and apparently only one brachiole. Osculocystis is based on a single specimen of the type species, O. monobrachiolata, from the lower Silurian of Buildwas, Shropshire. It is the first recorded lower Silurian cystoid from Britain and is most closely related to Glansicystis Paul.
