PHARCICERAS  HYATT, 1884 is the diagnostic ammonoid of the
 late middle Givetian Stage of the Middle Devonian Series.
It occurs in the Rhenish Massif in Germany, the Montagne Noire
in southern France, and in equivalent strata in the Anti-Atlas in
southem Morocco.  Verified North American occurrences of Phar-
ciceras are confined to the New York succession, where the ap-
pearance of the ancestral species P. amplexum (Hall, 1886) in the
Upper Tully Limestone represents an important and well-estab-
lished biostratigraphic datum within the Taghanic onlap interval
(see Aboussalam and Becker, 2001 for discussion).  In this note
we describe a second, distinctly younger, North American species,
Pharciceras barnetti n. sp., from the New Albany Shale in east-
central Kentucky that provides new evidence on the Taghanic
onlap interval (Upper Tully/Geneseo Sequence of Baird and Brett,
2003) in the central Appalachian Basin.  This occurrence is par-
ticularly significant because of its association with conodonts that
provide a basis for refined correlations between the central Ap-
palachian Basin and the Taghanic onlap succession in New York.
