eight species, of which five are new, while the others have all been 
found in the Corallian or Kimmeridgian of other localities. The 
beds are thus proved to be Upper Jurassic. In the specimen of 
Archæopteryx in the Berlin Museum, those parts are preserved 
which are wanting in the example in the British Museum, and 
the pelvis, hind-limbs, and more perfect tail supply valuable de- 
tails. These are worked up in the memoir “ Ueber Archæop- 
teryx” in the Palaeontologische Abhandlungen, Berlin, 1884, by 
:W. Dames. 
Cretaceous —The variability of ancient species is well demon- 
strated by five abnormal specimens of Hemiaster from the creta- 
ceous of Constantine, Algeria. In some of these one of the ambu- 
lacral areas is entirely or partially atrophied, while in others there 
is a doubling of one of the ambulacra. These animals, provided 
with four or six ambulacra, attained as full a growth as normal 
examples. 
Tertiary.—The series of tertiary deposits which lie along the 
Alsatian slope of the Vosges, and which are often rich in bitu- 
men, have by M. Blecher been determined to belong to the Ton- 
grian stage. The deposits are sometimes marly and of deep-sea 
origin, at others sandy and littoral, according to the widening or 
narrowing of the zone between the Vosges and the Black forest. 
The vegetable fossils are numerous and remarkable. 
Pomel considers the terrestrial deposits of the Sahara as forming 
two categories. The more ancient he places in the pliocene, and 
names Saharian. The author endeavors to show that, during the 
pliocene and quaternary, the maximum zone of precipitation was 
displaced northwards, and successively passed from the central 
Sahara to the Atlas, then to central, and lastly to northern 
Europe. 
BOTANY! 
THE FERTILIZATION OF THE MuLLEIN Foxctove (SEYMERIA 
MACROPHYLLA).—The mullein foxglove is similar to the passion © 
flower of Ohio in flowering for only one day. Both begin to 
flower early in the morning. Seymeria perishes with nightfall, 
the passion flower lasts till about midnight.
