Three genera of sponges are described for the first time from the Lower Palaeozoic of North Greenland. ?Vauxia gracilenta Walcott, 1920 and Choia hindei (Dawson, 1896) are reported from the Buen Formation of Early Cambrian age; the specimens of the latter species are the largest known examples of Choia. A single specimen from the Chester Bjerg Formation of Late Silurian age is described as Diagoniella mica sp. nov., and is the smallest known species of the genus.
