and occupy ourselves with the rocks and fossils of those localities containing 

 Ammonites, these being fossils ot the greatest value for determining the 

 stratigraphy of the Jura. 



In locality 4, 



South-western end of Windy Gully, 



(cf. p. 13 "Medium horizon" and Letter-press fig. 1, c; fig. 2, c) 



"about an hour's walk north-eastwards from Elmwood", Professor Nansen, 

 observed, on July 14th, 1896, at a height of about 400 feet (370-450 ft.) 

 above sea-level, "a clayey ridge with horizontal layers". Some of the fossils 

 collected here were, according to both Prof. Nansen and Dr. Koettlitz 1 , found 

 in situ. 



I have before me from this locality, 



Macrocephalites Kosttlitzi n. sp. in gray-brown phosphoritic clay; 



Belemnites sp. indet. 1. -- Fragments of large phragmacones in dark, hard, 

 phosphoritic nodules with a gray, clayey weather-crust and 

 numerous phosphoritic nodules without fossils. 



Among the material which E. T. Newton describes from this locality, 

 the following species, in addition to Macrocephalites Kosttlitzi n. sp. (Amm. 

 [Macroceph.] Ishmce "smooth variety"), and the Belemnite fragments, ought 

 to be specially noticed: 



Macrocephalites Ishmce var. arctica E. T. Newton, and 



pila Nik. (= Amm. [Macroceph.] Ishmae 



"inflated variety" E. T. Newton cf. p. 73). 



Being a new species, the present Macrocephalites Kcettlitzi n. sp. a 

 priori as little permits of any certain determination of the horizon as does 

 Macrocephalites Ishmce var. arctica Newton. Both species are allied to 

 Macrocephalites Ishmce Keys, sp., whose exact vertical position in the Pet- 

 chora basin is not yet known, although there is no doubt that the latter
