320 The Amefica?i Geologist. May, i9oo 
Only a few of the more glaring paleontological blunders in this 
paper have been pointed out, but the facts given are sufficient to show 
that, although Dr. Bose's paper may be an important contribution to 
our knowledge of the structure and origin of the central plateau of 
Mexico, his paleontology and the correlations based upon it are 
weak, and must be received with caution. t. w. s. 
The Jurassic fauna of Cape Flora, Franz Josef Land. By J. F. 
FOMPECKj. (Scientific result of the Norwegian North Polar expedition. 
Fridtjof Nansen, iSqq? New York, Longmans, Green & Co.) 
Nansen writes the geological sketch introducing the description of 
the fossils by Dr. Pompeckj. The locality is interesting, as being the 
farthest point north, to which the Jurassic fauna has been traced. The 
fossils are in soft shales which have been protected from the severe wear- 
ing action of glacial forces by a' protective covering of basalt. Nansen 
could not discover that the Jurassic clays were at all consolidated and 
suggests that their resistance to the pressure of the incumbent ig- 
neous rock may be due to their being perpetually frozen. 
The Jurassic strata of Cape Flora consist of about 575 feet of soft 
clay or sandy clay, which Dr. Pompeckj on the evidence of the fossils, 
refers to the Callovian section of the Jurassic, and of 525 feet of basalt 
which Dr. Nathorst on account of the plant remains would assign to the 
Oxfordian. A section is given at page 30. Numbers of concretionary 
nodules are found in the clay, and these were the principal source of the 
fossils. The fossils were in a very bad condition of preservation, but 
about 32 species were made out mostly Ammonites, Beiemnites, and 
lamellibranchs. 
Dr. Pompeckj considers that the discoveries at Cape Flora prove the 
existence of a Bajoccian sea north of the "Eurasian Jura continent;" al- 
so it extends the Callovian deposits nearly two degrees of latitude fur- 
ther north than had been previously known. Two plates of figures of 
the species found accompany the memoir, which is a quarto of 148 
pages. G. F. M.
