THE NORWEGIAN POLAR EXPEDITION. 425 



Nansen says: "Through Jackson's kindness and Koettlitz's valuable 

 assistance, I was enabled to make a collection of fossils and rocks from 

 the Jurassic deposits of this locality." 



"(Koettlitz) took me to places where, before my arrival, he had al- 

 ready found fossils, or had observed anything of importance. Had it 

 not been for him I should certainly not have been able to do what little 

 I did during the few days at my disposal. I agree with Koettlitz on all 

 essential points, and have nothing new of importance to add to what he 

 has already said." 



As Nansen elsewhere remarks, the memoirs of Pompeckj and Na- 

 thorst supplement the papers of Koettlitz, Newton and Teall, which 

 appeared in the Quarterly Journal of the Geological Society, 1897, pp. 

 477-519, and 1898, pp. 620-651. 



Pompeckj describes fully the various fossils, illustrates them with 

 wealth of detail, discusses their stratigraphical relations, and outlines 

 the paleographical history of Franz Josef Land. 



Of the twenty-six species collected by Nansen no less than seventeen 

 are new as compared with the Jackson-Harmsworth collection, which 

 contains five species lacking to Nansen. There are representatives of 

 single species only of echinoderms, vermes and gastropods, the scarcity 

 of the last named being generally characteristic of the Jurassic fauna 

 of the arctic regions, whether in Siberia, Greenland, or Arctic America. 

 On the other hand, at Cape Flora the cephalopods and the lamelli- 

 branchs predominate very largely. This fact makes most notable the 

 absence of the lamellibranch genus Aucella, with all other forms that 

 are especially characteristic of the higher Jura. 



The following new species have been determined by Pompeckj: 

 Pseudomonotis Jachsoni, an ornamented shell of a remarkably large 

 Aviculid form. Macrocephalites Eoettlitzi, a shell with a very narrow 

 umbilicus and almost completely encircling whorls. Cadoceras Nanseni, 

 an ammonite showing a flat disc-like growth, with moderately thick 

 whorls of which cross-sections are nearly elliptical. Another ammonite 

 may possibly be a variety of C. Nanseni, but Pompeckj considers that it 

 is a separate species owing to its wider umbilicus, less pronounced in- 

 volution and somewhat asymmetrical lobe-line. 



Pompeckj's outline of the paleontographical history of Franz Josef 

 Land is worthy of careful consideration by all interested in this depart- 

 ment of science, although many may differ from some of the conclusions 

 reached by him. Commenting on the stratigraphical studies of Prof. 

 E. T. Newton, Pompeckj states that his own investigations compel him 

 to differ materially from the inferences drawn and theories advanced by 

 that scientist. 



Pompeckj says: "The occurrence of these three genera of Ammonites 

 proves that the marine fauna of Cape Flora contain representatives of
