esc. aff. Nanseni and Leda cf. nuda Keys. sp. to the Middle Callovian. Frag- 

 ments of Belemnites m.f. subextensus Nik. Panderi d'Orb., a species we 

 already know as belonging to the Middle Callovian, were especially numerous 

 in the "moraine" at the side of the glacier. Most of the pieces are without 

 any adhering rock, and only one piece is enclosed in gray clay, weathered 

 a yellowish brown. In the same rock, besides several quite indeterminable 

 fragments of ammonites (Cadoceras ?) there were also various pieces of Cado- 

 ceras Tchefkini d'Orb. sp., of which the best is figured on PI. II, fig. 7. 

 Cadoceras Tchefkini -- as already stated --is one of the most important 

 fossils of the Middle, Callovian of central and northern Russia. 



Just as I now have before me fossils of the Middle Callovian from the 

 debris at the edge of the glacier NW. of Elmwood, so also does the material 

 which Newton examined from the same locality contain fossils of the 

 same horizon. Newton, as far as one can judge of the material described 

 by him, seems only to have had fossils of the Middle Callovian from this 

 locality. Besides Cadoceras Tchefkini d'Orb. sp., Nanseni n. sp., and Belem- 

 nites mf. subextensus Nik. -- Panderi d'Orb. sp., which I have before me, 

 there is also Cadoceras stenolobum (Keys.) Nik. a very characteristic species 

 of the Middle Callovian of Russia. 



The most interesting of the fossils collected on July 12th, 1896, at the 

 margin of the glacier, is unquestionably 



Quenstedtoceras vertumnum, Sintzow 1 . 



(P. 96 PI. II, fig 9.) 

 from gray clay, weathered a brownish yellow. 



Sintzow records this species from the zone of Quenstedtoceras Lamberti, 

 therefore from the 



Upper Callovian 

 of the Russian geologists, from the Sukhala Jelchanka in the government Saratow. 



Quenstedtoceras vertumnum was the first fossil that I was able to determine after 

 having received the material. Upon the occurrence of this species, I supported my 

 first statement (communicated to Professor Nansen) of the occurrence of the Lamberti 

 zone in the Jura of Cape Flora.
