They were almost invariably prostitutes.

Scortum--A strumpet. Secrecy is implied, but the word has a broad usage.

Scorta erratica | Clandestine strumpets who were street walkers.
Secuteleia |

Busturiae--Tomb frequenters and hangers-on at funerals.

Copae--Bar maids.

Delicatae--Kept mistresses.

Famosae--Soiled doves from respectable families.

Doris--Harlots of great beauty. They wore no clothing.

Lupae--She wolves. Some authorities affirm that this name was given them
because of a peculiar wolflike cry they uttered, and others assert that
the generic was bestowed upon then because their rapacity rivalled that
of the wolf. Servius, however, in his commentary on Virgil, has assigned
a much more improper and filthy reason for the name; he alludes to the
manner in which the wolf who mothered Rotnulus and Reinus licked their
bodies with her tongue, and this hint is sufficient to confirm him in his
belief that the lupa; were not less skilled in lingual gymnastics. See
Lemaire's Virgil, vol. vi, p. 521; commentary of Servius on AEneid, lib.
viii, 631.

AElicariae--Bakers' girls.

Noctiluae--Night walkers.

Blitidae--A very low class deriving their name from a cheap drink sold in
the dens they frequented.

Forariae--Country girls who frequented the roads.

Gallinae--Thieving prostitutes, because after the manner of hens,
prostitutes take anything and scatter everything.

Diobolares--Two obol girls. So called from their price.

Amasiae, also in the diminutive--Girls devoted to Venus. Their best
expression in modern society would be the "vamps."

Amatrix--Female lover, frequently in male part.

Amica--Female friend, frequently a tribad.

Quadrantariae--The lowest class of all. Their natural charms were no
longer merchantable. She of whom Catullus speaks in connection with the
lofty souled descendants of Remus was of this stripe.

From many passages in the ancient authors it is evident that harlots
stood naked at the doors of their cells: "I saw some men prowling
stealthily between the rows of name-boards and naked prostitutes,"
Petronius, chap. 7. "She entered the brothel, cozy with its
crazy-quilt, and the empty cell--her own. Then, naked she stands, with
gilded nipples, beneath the tablet of the pretended Lysisca," Juvenal,
Sat. vi, 121 et seq. In some cases they had recourse to a gossamer
tissue of silk gauze, as was formerly the custom in Paris, Chicago, and
San Francisco.
