Introduction. 



According to PER SCHEI'S investigations, the beautifully developed 

 Devonian Series at Goose Fiord in Ellesmere Land fall into two easily 

 recognised divisions. A lower one, at least 500 metres in thickness, 

 is mainly composed of dark limestone and schists, with a more or less 

 rich marine fauna. This series, D, appears in the sections on both 

 sides of Goose Fiord, from Borgen to the foot of Mount Varg, and 

 from the inner Fide to Skrap Valley. This is succeeded by an upper, 

 massive series, mainly consisting of quart/ sandstone, which consti- 

 tutes the mountains on both sides of the inner part of Goose Fiord. 

 SCHEI names this upper portion Series E. It presents an entirely diffe- 

 rent fades development to the lower series, and contains in certain 

 horizons only, fossils of plants and fishes. The former have been described 

 by G. NATHORST. 



The ichthyological remains which I shall describe in the following, 

 with lew exceptions belong to the upper series F. Only one specimen 

 is in our possession from the lower marine series D. 



I. Fish Remains From Series D. 



In his preliminary report, SCHEI mentions fish remains from two 

 horizons, Dg and Di, of the lower marine series D. According to the 

 notes which I made during my first examination of SCHEI'S material 

 there was also one fish remain from Dh. In the material to hand we 

 have only this last specimen. The others unfortunately must he assumed 

 to be lost. In my first examination of the material I noted traces of 

 Coccosteus (?). The determination, however, was very uncertain. As 

 regards Di I noted a large scale of Holoptyckius, which is found in 

 this horizon with a quantity of mussles (principally Modiomorpha sp.), 

 Gastropodes and numerous specimens of a Spirifer which according to 

 0. E. MEYER'S determination is Spirifer inflatns SCHNUR. This fauna 

 is an impoverished marine fauna, or possibly a rudimentary brackish 

 water fauna.
