TESTUDO, the tortoise, in natural his- 
tory, a genus of Amphibia of the order Rep- 
tiles. Generic character: body tailed, 
covered above and beneath, defended by a 
bony covering, covered by a horny, scaly, 
or coriaceous integument ; a bony mouth, 
without distinct teeth, and the upper man- 
dible closing over the lower. These animals 
feed on sea-weeds or on worms, are ex- 
tremely prolific ; but in the state of eggs, 
and while very young, are the prey of vari- 
ous animals. Their movements are slow ; 
they are capable of being tamed, and will in 
that state eat almost any thing presented 
to them. They exist long in such air as 
would be destructive to other animals of the 
same size, and have such tenaciousness of 
life, that it is stated they will exhibit convul- 
sive movements for several days after their 
bodies have been opened, and even after 
their heads have been cut off. In cold lati- 
tudes the land tortoise is torpid during the 
winter. There are thirty-five species, of 
which we shall notice the following. T. 
Graeca, or the common tortoise. Tiie weight 
of this animal is three pounds, and the length 
of its shell about seven inches. It abounds 
in the countries surrounding the Mediterra- 
nean, and particularly in Greece, where the 
inhabitants not only eat its flesh and eggs, 
but frequently swallow its warm blood. In^ 
September or October it conceals itself, 
remaining torpid till February, when it re- 
appears. In June it lays its eggs, in holes 
exposed to the full beams of the sun, by 
which they are matured. The males will 
frequently engage in severe conflicts, and 
strike their heads against each other with 
great violence, and very loud sounds. Tor- 
toises attain most extraordinary longevity, 
and one was ascertained to have lived in 
the gardens of Lambeth to the age of nearly 
120 years. Its shell is preserved in the ar- 
chiepiscopal palace. So reluctant is the 
vital principal to quit these animals, that 
Shaw informs us, from Redi, one of theip 
lived for six months after all its brain was 
taken out, moving its limbs, and walking 
as before., Another lived twenty-three days 
after its head was cut oft', and the head itself 
opened and closed its jaws for a quarter of 
an hour after its separation from the body. 
It may not only be tamed, but has in seve- 
ral instances exhibited proofs in that state
