132 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA, [norw. POL. EXP. 



nite was obtained, which is probably Ammonites Tchefkini. In the water- 

 course below this exposure, similar ammonites were found, together with 

 A. modiolaris and A. macrocephahis. These suffice to settle the age as 

 Lower Oxfordian, and probably the equivalent of our own Kellaways Rock; 

 and although only one ammonite was found in situ, yet it is sufficiently 

 certain that the others, if not from the same place, came from beds but little 

 lower in the series. Similar fossils to these occur in the talus at many places 

 around Gape Flora, showing that the same beds in all probability occur all 

 around the Gape." 



A few lines further on, Newton settles the age of these fossils as the 

 "Ammonites macrocephalus horizon." 



Newton's determination of the fossils from this locality is erroneous in 

 some cases; his Amm. macrocephalus is Cadoceras Nanseni n. sp. ; his 

 Amm. modiolaris is partly Cadoceras Tchefkini d'Orb. sp., partly Cado- 

 ceras stenolobum (Keys.) Nik.; his Amm. Tchefkini ? d'Orb. is partly really 

 Cadoceras Tchefkini d'Orb. sp., partly Cadoceras stenolobum (Keys.) Nik. 

 All the fossils, like those from this locality that I have examined, point to 

 the Middle Gallovian, the zone of Reineckia anceps or of Cadoceras Mila- 

 schewici, not to the Lower Callovian, nor to the "Ammonites macrocephalus 

 horizon." Macrocephalites macrocephalus Schloth. sp. is not among the fos- 

 sils hitherto known from the region of Gape Flora. 



Newton must consequently declare the beds at the southwest end of 

 Windy Gully — in situ, according to Prof. Nansen and Dr. Kceettlitz, 50— 

 180 ft. deeper — to be older than his "Ammonites macrocephalus horizon". 

 He described them as "perhaps of the age of the Cornbrash" (1. c. p. 513). 

 We recognised in them representatives of the Lower Callovian, of the zone 

 of Macrocephalites macrocephalus of Oppel, or of that of Cadoceras Elatmoe 

 of Nikitin. 



Newton's paper contains no information as to the occurrence of the Up- 

 per Gallovian in the region of Gape Flora. 



Concerning the age of the hard, sandy marls, and the light, soft marls 

 lying at a height of 23—33 ft. above the sea, which we designated as (Lower) 

 Bajocian, Newton expresses no opinion.
