Custos

(warden) is specially the treasurer or chief sacristan in a foreign cathedral. SEE CUSTOS ARCAE.

There were anciently also various others thus designated: the custos ordinis, one of the great monastic officers, the third and fourth priors, who acted as the rounds; the custos feretri, the shrine-keeper; the custos operis or fabriae, the canon in charge of repairs of the building, in secular cathedrals; the four custodes at Exeter, attendants in the sacristy, bell- ringers, and marshalmen in processions; and the custos puerorum at Salisbury, a canon who had the supervision of the choristers. — Walcott, Sac.
