Grania paucispina (Eisen, 1904) and Grania incerta sp.nov. are described, both found in marine sands of California and British Columbia. The species are closely related. Their setae are morphologically very similar, and they both have small glands at their spermathecal openings which distinguish them from other species of the genus. They differ from each other primarily in the distribution of the setae and in body appearance.
