124 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [norw. pol. EXP. 



With the exception of Discina sp. indet. and Belemnites sp. indet. 2, 

 specimens of all the forms were found in large numbers, and, with the 

 exception of these two forms, the species were all found both in situ and 

 also loose, weathered out of the rock. 



There are, moreover, very numerous remains of Lamellibranchs, but in 

 so bad a state of preservation, and so fragmentary that they cannot be 

 determined. 



In the report of the Jackson-Harmsworth Expedition ^ mention is also 

 made of 



Avicula sp. cf. inoequivalvis (Pseudomonotis Jacksoni, n. sp.) 

 Belemnites div. sp. indet. 

 from the same iocahty, "SW. of Elmwood," "sandy shale." 



Newton further mentions from this Iocahty an "indeterminable" fragment 

 of an Ammonite, which he determines as "allied to^. Qowerianus". As neither 

 description nor figure of this specimen is given, it is, of course, impossible 

 to judge how far Newton's determination is correct. As no trace of Ammo- 

 nites was to be found in the rather abundant rock-material which I 

 examined from this locality, I am of opinion that the fragment mentioned 

 by Newton does not originate from the rocks lying 23—33 ft. above the sea, 

 but that it may have fallen from higher beds. Moreover, as Newton does 

 not take this ammonite fragment into stratigraphic consideration at all, we 

 may also ignore the reference to the Callovian, made on account of the 

 "affinity" to Gosmoceras (Keppleritis) Gowerianum Sow. sp. (if Newton's 

 determination be correct), in the discussion of the age of the strata lying at 

 a height of 23—33 ft. above the sea. 



The great vertical distance between these beds and those of the Lower 

 Callovian, situated at a height of 400 ft. above the sea, would a priori 

 justify the supposition that here at Elmwood older horizons are developed 

 than the Lower Callovian at the south-west end of Windy Gully. As far as 

 the fossils from our locality No. 1 were determinable, the fauna fully confirms 

 this opinion. It shows a composition wholly different from that with which 

 we are acquainted in the fauna of the Callovian of Windy Gully, above Elm- 

 wood, and at the edge of the glacier.
