and, still more, with those in the Conglomerate section containing 

 Spirifer supramosquensis. In addition to this Spirifer the material 

 contains a fragment of a very small brachiopod shell preserved in 

 light-blue calcedon, which forms a connection with specimen 16, 

 which, however, is somewhat more red-gray and lighter in colour, 

 and is a denser limestone. This fragment (N:o 158} contains, in 

 addition to the above-mentioned brachiopod-shell in blue chalcedon, 

 probably belonging to a species of Chonetes, a couple of indetermin- 

 able shell-fragments of another brachiopod and crinoid stems. The 

 third piece, 17, which Wegener wishes to place in the same 

 category with the two already mentioned, presents some points of 

 dissimilarity from these. The rock {N:o 160) is a light red-gray 

 limestone, containing both larger and smaller fossils. Of brachio- 

 pods it contains a somewhat large dorsal valve of Productas punctaius 

 Martin, and a couple of compressed and badly preserved specimens 

 — both the ventral and dorsal valves — of a species of Produdus be- 

 longing to the semireticidatus group, and a little ventral valve of another 

 Produdus. In the rock there lie scattered fine, short spines of Prod, 

 punctatus, and also coarser, as much as 2 cm, long spines of the 

 species belonging to the semireiiculatus group. Of smaller fossils the 

 material contains numerous crinoid stem-joints, and also some scat- 

 tered specimens of Fusulinella. 



Even if the darker {158} and the lighter limestone (160) present, 

 exteriorly, a certain dissimilarity, still, the texture of the rock in 

 both is fairly analogous and, under the microscope, the two speci- 

 mens have a great resemblance to each other and to the red lime- 

 stone {N:o 136). The dark limestone contains a fairly large amount 

 of a dark clayey substance filling the interstices between the part- 

 icles of calcite, and has only rarely foraminifera, partly rotaliform 

 and partly of the genus Tetrataxis. The light-red limestone shows 

 numerous sections of Fusalinidœ. 



The Eastern River. 



Farther to the east, at the river in the immediate neighbour- 

 hood of the camping-place, Wegener has measured a profile through 

 the strata, or, more correctly speaking, he has made two, connected 

 with each other, the one at the mouth of the river, embracing 

 Wegener's specimens 18-23, and one farther up the river: spe- 

 cimens 24—31. 



The lowest levels in these profiles present a certain likeness 

 to the rocks from the hill-lops farther to the west, and, according 

 to Wegener's sketch, they should lie pretty close above these 

 latter.
