16 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [NORW. POL. EXP. 



mudstone-bands are exposed, and at this spot I found in place the small am- 

 monite which Mr. Newton thinks is in all probability Ammonites Tchefkini" l . 

 Koettlitz probably also refers to the same place when he says: n Layers of 

 hard, grey, ferruginous mudstone-nodules occur in the shales, and sometimes 

 form bands as much as 2 feet thick" 1 . It ought to be remembered that 

 the word n shales" here means quite soft clay or sandy clay. I am not quite 

 certain that Koettlitz is right when he says 50 feet below the basalt. The 

 fossils and nodules lying loose along the water-course were certainly found 

 as low as that, or even lower, but it seems to me doubtful whether this was 

 the case with the fossils found in situ.

As being originally derived from a doubtful height possibly from this 

 same locality or somewhat lower, I may here mention some fossils (ammonites) 

 found on July 10 th ' 1896 below this place, at a height of about 30 metres (100 feet) 

 above the sea. They were found in fragments of stone-nodules 2 , which lay 

 scattered loose amongst the basaltic debris on the talus, and had evidently 

 come from some higher level. Pieces of marly limestone, with cone-in-cone 

 structure, were also found in the same place. 



5. Strata immediately below the basalt. Fig. l,f,f; fig. 2, f. 



On July 24 th - 1896, Dr. Kcettlitz and I visited the top of the talus (575 

 feet above the sea), a little east of Elmwood, above Sharp's Rock (a loose 

 basaltic rock lying on the raised beach). 



We here found the clay deposits exposed in situ just below the base of 

 the basalt, and could examine their contact with the latter. No fossils were 

 found at this spot. The clay deposits showed distinct stratification, and spe- 

 cimens of the various strata were taken, but no appreciable alteration by con- 

 tact with the basalt could be detected. Newton and Teall have given the 

 following description of these strata in descending order: 



(!) Black shale 4 inches thick, from just below the basalt. There is no 

 appearance of this shale having been heated to any extent by contact 

 with the basalt.
