POPULAR SCIENCE REVIEW. 
With regard to the presence of Cretaceous rocks in Jezo, the case is 
different. The statements of Dr. Naumann relate to a series of Cephalopoda 
collected in that island by B. S. Lyman, including sixteen species, seven of 
which can he identified with certainty with previously described fo rms . 
The evidence thus furnished, and the general character of the species, 
indicates a close agreement with the fauna of the Upper Cretaceous of 
Southern India, as described by Forbes and Stoliczka, which includes all 
the above-mentioned seven described forms. The species from Jezo are as 
follows : — 
Lytoceras Sacya, Forbes. 
Phylloceras, n. sp. (allied to Indr a, Forb.). 
(P subalpinus , Orb.). 
Velledce, Mich. 
Amaltheus Sugati, Stol. 
Haploceras, n. sp. 
planulatum, Forbes. 
Gardeni, Baily. 
Stoliczkaia, sp. 
Anisoceras tenuisulcatum, Forbes, 
sp. 
n. sp. 
Ptychoceras gaultinum , Piet, 
n. sp. 
n. sp. 
According to Baily and Griesbach, this horizon is similarly developed in 
South Africa ; and it would appear that the Cretaceous formation of 
Sachalin, described by F. Schmidt, is connected with that of Jezo, so that, 
in all probability, we have to do here with a continuous marine province of 
the Cretaceous period, surrounding the whole southern and eastern border 
of the African and Oriental continent. 
Of the above species, three, namely, L. Sacya, Ph. Velledce, and Pt. 
gaultinum, are cited by F. Schmidt from Sachalin, and the fourth recorded 
Ammonite from that island {Haploceras peramplum, Mant.), is considered 
by Dr. Naumann to agree with his supposed new species of that genus.

The Oldest Flowering Plants . — Count de Saporta and M. A. F. Marion 
recently brought before the French Academy of Sciences a joint memoir on 
the genera Williamsonia and Goniolina, the most ancient forms of flowering 
plants of the fructification of which anything definite is known. In William- 
sonia the trunk bears at its extremity the organs of reproduction, which 
show two distinct forms, apparently indicating that the plant was dioecious, 
but in both there is a multifoliate envelope, which acquires a globular form 
by the curvature of the bracts composing it. 
The parts of the envelope of the male flower seem all to stand at the 
same level : they are elongated, narrowed, and bent towards each other at 
the apex. Within the envelope rises a conical axis, the base of which is sur- 
rounded by a circular zone, with radiating striae. The outer margin of this 
zone, when exposed, is found to be covered with a number of very small 
irregularly hexagonal areas, which seem to represent so many pollen-cells.
