COTERELLUS and Cotarius, terms used, according to Spelman and Du Fresne, to designate servile tenants; but in Doomsday-book and other ancient manuscripts they seem to be distinguished as well in tenure and quality as in name; for the cotarius had a free soccage tenure, and paid a stated firm or rent in provisions or money, with some occasional customary services; whereas the coterellus seems to have held in mere villenage, and his person, issue, and goods, were disposable at the pleasure of the lord.
