Abstract
This family includes two of Savigny's genera—Boltenia and Cynthia, and may be defined by their common characters if we omit or modify one point on which considerable stress is usually laid, namely, the number of lobes round the branchial and atrial apertures.The amended definition of the family is as follows:—Body attached, sessile or pedunculated; apertures four-lobed or having less than four lobes.Test coriaceous; rarely cartilaginous or gelatinous.Keywords
