The collection from Atanekerdluk contains in almost every slab, amidst very numerous 
annual twigs, several which are very large (Plate LV. fig. 3 a) or of considerable length 
(one of 100 millims. in length), indicating a luxuriant growth. Some twigs with imbri- 
cate leaves had female flowers (Plate XLIV. figs. 2, 3). 
Plate XLIV. fig. 4 represents a small oval catkin, probably male ; fig. 3 b, a seed. 
In the large slabs I found several ripe cones, the scales of which are spread open and 
separated. Plate XLIII. fig. 2 «, and Plate XLVI. fig. 7 b represent the transverse 
section of a cone, and Plate XLIII. fig. 1 a longitudinal section ; fig. 2 b are leaves, 
and fig. 2 c a branch. 
A scale of Sequoia was found in a nodule from Atanekerdluk (Plate XLIII. fig. 3).

This appears to have been the commonest coniferous tree on Disco. Its twigs and 
fragments of cones are frequent in the sandstone and the siderite of Kudliset and Ujarar- 
susuk. The finest specimen from Kudliset is represented in Plate XLI. On the older 
twigs are broad, scale-like imbricate scars (Plates XLI. fig. 1 ; XLII. 1 a) as on the 
biennial twigs from Bovey (Bovey Tracey, pi. viii. fig. 10). The lower parts of the 
branches are nearly smooth. Leaves of the young shoots falcately curved, acuminate, 
decurrent, and covering the twigs, sometimes very close together (Plate XLI. fig. 5), as 
in S. Sternbergi, at others, perhaps on young, lengthened shoots, more distant (fig. 3). 
The leaves in Plate XLI. fig. 4, and Plate XLII. fig. 1 c are not falcately curved, and 
are less acuminate, but appear to belong to this species. Plate XLI. fig. 9 represents a 
ramified twig, with scale-like adhering leaves, and bearing an oval body, probably a male 
catkin, such as I have described from Bovey Tracey (Plate XLII. fig. 43) ; the cone of 
this species is on the large slab (Plate XLI. fig. 7). In consequence of pressure, the 
shape has been altered, still one recognizes the peltate scales, which are cuneate at the 
base. At the base of one of these scales is an indistinct oval body, probably originating 
from the seed. The scales in Plate XLI. fig. 7 are in a lateral position. Plate XLII. 
fig. 1 d (from Ujararsusuk) represents their upper sides, and enables us better to deter- 
mine their shape and size. They are 8 millims. broad and 7 long, polygonal, with a
