series of non-fossiliferous, red, white and green sedimentary 

 rocks which here underlie the Rhaetic strata, and to which he 

 also referred a ruddy sandstone and a calcareous conglomerate, 

 which was met with on the Fame Islands underlying a sheet 

 of Labrador porphyrite. 



By reason of their stratigraphie situation and pétrographie 

 character Nathorst hesitatingly classed these last-mentioned 

 rocks as Keuper. I had no opportunity myself of examining 

 the strata on the W, side of Ryders River, but on the shore 

 I collected a few samples during a single, short tour. From 

 the Fame Islands Dr. Deichmann brought back a few samp- 

 les, about which I shall have something to say below. 



During my own wanderings I came across, on the W. slope 

 of Liverpool Land, a curious conglomerate that is probably 

 identical with the one pointed out by Nathorst and mentioned 

 above. In the main it forms a firm mass, the pebbles of which, 

 it is true, stand ont plainly against the matrix, but yet are so 

 firmly connected with it that they cannot easily be isolated 

 even with the hammer. Since the matrix itself both prepon- 

 derates in bulk and presents a tolerably compact appearance, 

 while the fragments show angular shapes, the whole strongly 

 reminds us of a volcanic breccia. But we have none such 

 here; firstly a stratification can already be seen macroscopically, 

 and secondly the microscope shows conclusively that we have 

 here a clastic rock consisting of numerous grains, mostly 

 quartz, but also felspar, and besides, in certain thin ledges, 

 much garnet and iron- ore. As a rule these grains are sharp- 

 edged, and as a typical cementing material is only sparsely 

 present, the rock has a fairly crystalline look. But there occur 

 also numerous grains, often well rounded, of rock-fragment, 

 among them even micro-pegmatitic intergrowths of quartz and 

 felspar, and their shape already shows that the whole is, after 

 all, a clastic mass. That this is the case appears still more 

 plainly in some intervening layers of green or red true clastic
