1898] NOTES AND COMMENTS Zal 
xxvi., June 21, 1898), and the following are their chief conclusions. 
The Cretaceous and Tertiary rocks lie unconformably on a hilly base- 
ment of old crystalline rocks and early Cretaceous basalts, and reach 
at Atanikerdluk 3040 feet above the sea. Along the north side of 
the peninsula the Lower Cretaceous beds have an easterly dip, 
although the higher beds appear towards the west, probably in con- 
sequence of faults. The sediments appear to have been derived 
from the east, in which direction are few marine but some fresh- 
water fossils. The deposition of sediment seems to have been con- 
tinuous in some portion of this region throughout Cretaceous and 
early Tertiary times, although minor movements and erosion may 
have affected the beds before they were covered by the Tertiary 
basalt cap. The entire thickness of the sedimentary rocks is over 
3500 feet. 
These beds were divided by Heer into four series, on the basis 
of their vegetable contents. Of the lowest of these, the Kome.series, 
developed on the north coast of the peninsula, a thickness of pro- 
bably not over 700 feet is exposed above tide. The discovery of 
additional dicotyledons in the Kome series, from which hitherto only 
Populus primaeva was known, and which was regarded as Urgonian 
in age by Heer, casts serious doubt on the reference of those beds 
to so low a stage in the Lower Cretaceous. The flora as a whole is, 
however, to be compared with that of the Virginian Potomac forma- 
tion, with some, perhaps the upper, portion of which the Kome 
series 1s probably synchronous. 
The Atane series, hitherto not positively known on the north 
shore of Nugsuak peninsula, is clearly present at Ujarartorsuak with 
characteristic Atane plants. Farther west, at Kook Angnertunek 
and Niakornat, the dark homogeneous shale series probably repre- 
sents both Atane and Patoot members of the Upper Cretaceous, since 
of the marine organisms found here some are identical with those 
occurring at Ata and Patoot, the typical localities for the two 
divisions of the Upper Cretaceous. The marine invertebrates from 
the Atane series, which Heer correlated by means of fossil plants 
with the Cenomanian of Europe, strongly indicate that the series is 
to be correlated with Fort Pierre and Fox Hills or Montana forma- 
tion of the western United States. By means of its fossil plants 
the Atane series is so closely related to the Vineyard series of 
Martha’s Vineyard, the Amboy clays of the Raritan region of New 
Jersey, or the uppermost Potomac of Alabama, as to furnish strong 
reason for the belief that the middle one of Heer’s groups is the 
Greenland contemporary of the Amboy clays. The Patoot series, 
which appears lithologically and stratigraphically to be inseparable 
from the Atane series, contains at the same time many plants 
common in the upper part of the Amboy clays, with others allied
