a generalized type of sirenians. They had large 
tusk-like upper incisors, as in Halicore, and an ossified 
femur articulated with the pelvis. Remains of individuals 
of the family have been found in many places in Europe, 
and several genera have been separated from Halitheri- 
shell. The shell is ear-shaped and flatly spiral, with the ap- 
erture almost coextensive with the shell and limited only 
of extinct Sirenia from the Miocene, the type 
of the family HalitJieriida?. It appears to have pos- 
sessed distinct though small hind limbs, no trace of which 
has been found in any of the existing sirenians. Also

Specifically (o) In medieval palaces and castles, the main 
room, often the only living-room. Besides the hall, in very 
early times, even in the greatest houses, there were only 
a few sleeping-rooms, and not always these. In such a 
hall the lord and his family, retainers, servants, and vis- 
itors were all accommodated, and all public and house- 
hold affairs were carried on. Later rooms more retired 
were added, but throughout the feudal period the hall 
remained the common center of activity. Westminster 
Hall in London was originally a part of the royal palace, 
where all the common life of the royal court was conducted 
and the king dispensed justice. This great room continued 
to he the principal seat of justice in England till 1820.

Chaucer, Nun's Priest's Tale, 1. 12.

fus, or possibly rebuilt ; a room of that description being 
too necessary an appendage to a palace ever to have been 
neglected. Pennant, London, p. 114.

(2) The public or common room of a manor-house, serving

Oxford and Cambridge in England, the specific name of 
a college. The number of colleges called halts (a term 
which, as well as house, was originally applied to the resi- 
dence of the college scholars) in these universities, once 
considerable, is now small and diminishing.
