Changes in Facies and Biological Conditions. 



Kven in the uppermost part of the underlying marine series 1) \\e 

 observe the commencement of distinct changes of facies. In his preli- 

 minary report Scliei remarks on Ihis point (page 7(. 



. \hove Ilie-e layers (/.one Dgl there are hanks of purer limestone 

 I Mi. and then again more impure ones. Di. The upper layers of Di 

 allernalc with layers of light grey quart/ sandstone, and below with a 

 da\ sandstone, that in places bears a number of badly preserved 

 fos-il-. amongst which are Lamellibranchiates, Declienella, sp.. remain- 

 of lloloptychius etc. At the same time this layer of clay sand-tour 

 is the last member of series D, which is the first member of series E. 

 a huge series of quart/ sandstone strata, that form the mountains on 

 both sides of the inner part of Goose Fiord". This "sandstone point" 

 fauna is an impoverished marine fauna; it is possible that the appe- 

 arance of an abundance of mussels, presumably a Modioniorplia, and 

 the occurrence of Holoptychius scales, indicates that even as earl\ a- 

 Di we have a brackish water facies. 



An upheaval of Ihis region thus commenced at the end of the period 

 in \\hich series 1) was deposited, and continued in the succeeding period. 

 The huge sandstone series in series K must in fact be regarded as a 

 rontinental formation, corresponding as regards its facie- to the Catskill 

 if .\e\\ York and Pensylvania, or to the Upper Old Red in Europe. 



The fossiliferous hori/oii in Skrap Valley, with its grey and red, 

 iil'len conglomerate sand-lone, now indicates that in the middle of the 

 continental period there took place a brief subsidence with the formation 

 id a new brackish lake. This is indicated by the appearance in large 

 qnanlitie> of a -mall mussel, which must be regarded as a deformed 

 form of I'lilunia ri/limlricfi ll\i.i.. which otherwise is found in marine 

 facie-. With the latter \\ e find remains of plants, often badly preserved, 

 and remains of a somewhat abundant lish fauna. The remains are 

 \ery fragmentary and consist of various detached scales and fragment- 

 of plalr-, which have been divided and crn-hed into small piece-, and 

 then embedded promiscuously m the banks of sandstone, which are 

 often of a conuloiiifi-ale character: but the sculpture of the >pecimen-

 are able to form a conception of lhi> remarkable and long extinct

The ino-l fanla.-lic form- in the latter belong to the Hothfinli'fris
