_JIn northern British Columbia, in the Stikine map-area, Upper Triassic
fossils have been collected from the sedimentary group of the Triassic
series (Kerr, 1948). Fossiliferous strata on Kirk Mountain can be cor-
related with the highest Pardonet beds, and north and west of Flag Creek
can probably be correlated with some of the lowest Pardonet beds. The
Thibert group in the Dease Lake area (Kerr, 1926) may be equivalent in
age to some part of the Pardonet beds.

_ Triassic beds are known in parts of the Yukon. The Monotis sub-
circularis and Monotis alaskana var. zones of the Pardonet beds occur in a
section near the forks of Rakla River (Keele, 1906). Lees (1934) has
recognized beds of Upper Triassic age in the Lewes River group of the
Teslin-Quiet Lake map-area, Yukon. That part of the group with Monotis
subcircularis can be correlated with the highest Pardonet beds; the part
with Juvavites subinterruptus Mojsisovics can be correlated with much
lower Pardonet beds.

Upper Triassic strata are present in southeastern Alaska in Chitina
Valley (Smith, 1927). The Chitistone formation carries Tropites, which is
also present in the lower part of the Pardonet beds. The Nizina limestone
is unfossiliferous, and the higher McCarthy formation carries Monotis
subcircularis and so can be correlated with the highest Pardonet beds.
The iossiliferous strata on Stelna Creek, from which Smith (1927) has
recorded Halobia dilatata Kittl, may be equivalent to some middle part of
the Pardonet beds.

On Vancouver Island the Sutton limestone in the Vancouver group
carries Upper Triassic fossils in the Cowichan Lake area (Clapp and Shimer,
1911). These fossils have nothing in common with those of the Pardonet
beds, but may be close in age to high, but not the highest, Pardonet beds.
The fossiliferous beds of the Bonanza group in the Nimpkish area (Gunning,
1932), with Jfonotis subcircularis, are of the same age as the highest Pardonet
beds. Strata of this age are present in the upper part of the Parson Bay
formation on Harbledown Island (Crickmay, 1928). Fossiliferous beds
with Tropites and other fossil species collected by Gunning on Quadra
Island are to be correlated with the lower part of the Pardonet beds.

In Houston Stewart Channel, Queen Charlotte Islands, argillites and
limestones with Monotis subcircularis are equivalent to the highest Pardonet
beds, and fossiliferous strata on Frederick Island are of the same age
(MacKenzie, 1916).

The Triassic of the Hawthorne and Tonopah quadrangles, Nevada,
has been described by Muller and Ferguson (1939). Comparison of the
zones of the Pardonet beds with this Nevadan section has been attempted
by McLearn (1947). The Tropites zone of the Pardonet beds can be
correlated with the late Karnian Tropites subbullatus zone of the Luning
formation. The Stikinoceras fauna has no exact counterpart in the Luning,
but may be only a local, Peace River, phase of a part of the Tropites fauna.
The same may be true of the ‘Styrites’ treneanus fauna. The Hzmavatites
fauna has no exact counterpart in Nevada. Possibly it is in part equivalent
to the early Norian (Haloritan) Sagenites cf. giebeli fauna of the Gabbs
formation, or may represent an horizon in barren strata above the level of
S. cf. giebeli in the Gabbs. M. alaskana does not appear to extend as far
south as Nevada. Monotis subcircularis is not recorded from the Hawthorne-
Tonopah quadrangles; Muller and Ferguson (1939), however, consider that
