'Flagstones! is merely a convenient name for the higher of the above two units, and is only partly descriptive. It consists of flaggy, thin- bedded calcareous, grey siltstones; fine, calcareous, massive sandstones; and limestones.» The massive sandstones and limestones of this unit are present in the Mount Wrisht section on Halfway Riven but have not been observed in Hage Creek seation in Sikanni Chief Valley; these massive beds recall a similar lithology in the 'Grey beds!. It is probable that the name "Toad" can be carried south at least as far as Halfway Valley, and applied to the dark siltstones and limestones that underly the 'Flagstones! and carry the Beyrichites-Gymnotoceras fauna, Jt is not known as yet what underlies the Toad formation in these valleys. el

| the Triassic section in Prophet River basin has not been Sento the writer, but fossil collections received from there suggest that it is much like that in Sikanni Chief and Halfway Valleys.

Farther north, in Tetsa and Liard River Valleys, the Pardonet beds and the upper part of the 'Grey beds! have disappeared; the decapitated 'Grey beds! are incorporated in the Liard formation; the 'Dark siltstones! and 'Flagstones! have not. been recognized but equivalent beds may be included in the lower part of the Liard formation; and the Toad Perma tion is present an taaentaie by the shales of the Grayline formation, definitely exposed on Liard River and possibly also on Tetsa River. The seotion is as follows:

Liard formation (at top) Toad formation Grayling formation

The Liard formation is made up of massive, grey, calcareous, fine mana tenee and limestones, and carries the Nathorstites fauna; the Toad formation is composed of dark shales, shaly siltstones, and Tinea tones and carries the Wasatchites and Beyrichites— ymnotoceras faunas; and the Grayling formation consists of shale. The names Liard, Toad, and Grayling

have all been introduced by E.D. Kindle for the Liard River section.
