The United
StatesNational Museum has
recentlyprocured, through
the firm ofWilhelm
Schliiter of Halle,Germany, two
skinsanil skulls of
Rupicapra from
theEtruscan Apennines
in the region ofMount Comero and
theheadwaters
of theSavio
River.They were
at firstsupposed
to representRupicapra
ornata,hut more
carefulexamination shows
thatthey have none
of the peculiarities of theAbruzzian chamois. While agreeing with
the alpineanimal
in erectness of thehorns and
in the color pattern of the
neck and
throat,they
differ so noticeablyin size ofboth
incisiform teethand cheek
teethfrom
theelevenspecimens
ofRupicapra
rupicaprawith which
Ihave compared them
that thereseems
