130 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [norw. pol. exp. 



The Upper Gallovian 

 [= zone of Peltoceras athleta, = zone of Quenstedtoceras Lamberti). 



Information concerning this zone has hitherto only been obtained from a 

 piece of clay found loose near the margin of the glacier NW. of Elmwood, 

 and containing Quenstedtoceras vertumnum Sintzow. Rocks of this zone 

 have not hitherto been observed in situ with any certainty, but it is probable 

 that the clays near the lower limit of the basalt above Elmwood, at a height 

 of 575 feet above sea-level, are to be referred to the Upper Gallovian. 



From the foregoing remarks, we may draw up the following table (p. 131) 

 of the stratigraphic proportions of the Jura in the Cape Flora district. 



It is impossible from the material before me to determine whether the 

 great gap between the (Lower) Bajocian and the Lower Gallovian in this 

 profile includes a representation of the younger Bajocian and the Bathonian. 

 Apparently no exposures of rocks in situ have been observed between the 

 (Lower) Bajocian — from 23 to 33 ft. above the sea — and the Lower Gallo- 

 vian — 370—450 ft. — ; as everything here appears to be covered by talus 

 heaps. 



It is also impossible to determine the true thickness and limits of the 

 different zones. We can only show that the Gallovian in the district of Gape 

 Flora has a thickness of at least 200 ft., which is a thickness seldom attained 

 by the Gallovian of Europe and which is only surpassed by the deposits of 

 the same age in England and NW. France. 



The results of our investigations differ in no slight degree from those 

 which Newton arrived at from his examination of the Jackson-Harmsworth- 

 Expedition material i. 



In his stratigraphic inferences, Newton starts from his locality "3. Elm- 

 wood" e. p. (our locality 5, watercourse below the basalt above Elmwood). 

 Here, at a height of about 550 ft. above the sea (according to Dr. Kcettlitz), 

 interstratifications of clay-sandstone are exposed, which, according to our 

 determination, belong to the Middle Gallovian. I here quote from Newton: 

 "At this spot a bed (No. 3) was found in situ, and from it a small ammo-
