The various fossils which were found loose belong to various faunistic 

 horizons. 



In the first place, Cadoceras Frearsi (d'Orb.) Nik. 2 p. PL II, fig. 10, must 

 be referred to the Lower Callovian ; probably also Macrocephalites sp. p. 73 

 PI. II. fig. 11 (from its affinity to Macrocephalites Kcettlitzi n. sp. and there- 

 fore to the group of Macrocephalites IshmceKeys. sp.). The two forms, of 

 each of which there was only one specimen, were found without very much 

 rock adhering to them. Judging from the nature of the nuclei, however, they 

 have doubtless come from clayey rocks. These two Ammonites here represent 

 the horizon that was found at the south-western end of Windy Gully, at a 

 considerably higher level - - ca. 400 ft. above the sea i. e. the zone of 

 Macrocephaliles macrocephalus. 



To the same horizon most probably belong a few casts of umbilici 

 of Cadoceras sp. indet., consisting of blackish phosphorite with a pale gray, 

 clayey weather crust. In these umbilical casts, I found, besides Serpula 

 flaccida Goldf., a small fragment of a Cadoceras, whose lobe-line recalls the 

 characteristic species of the Lower Callovian of Russia, viz. Cadoceras 

 Elatmce Nik. 



To the Middle Callovian belongs a piece of clay- sandstone, containing 

 Cadoceras sp. ex. aff. Nanseni n. sp. (p. 92, PI. II, fig. 4), which is nearly 

 allied to our Cadoceras Nanseni, and Leda, cf. nuda Keys. sp. (p. 66, fig. 11). 

 Leda nuda Keys. sp. has, indeed, been found in the Petchora basin in the 

 Upper Jura, and moreover, is mentioned from Spitzbergen, from the Aucella 

 strata. Our form could not, however, be directly identified with Leda nuda 

 Keys, sp.; it was only admitted that it resembled that species. The rock 

 agrees perfectly with several pieces of the clay-sandstone in situ above 

 Elmwood, 550 ft. above the sea, which we have decided is Middle Callovian. 

 I therefore have no hesitation in also referring the rock with Cadoceras sp.
