1883.] Geology and Paleontology. 311 
—tThe previously noticed paper upon Earth Movements, by 
Professor J. Milne, of Tokio, Japan, appears in the Geological 
Magazine for November, and the same number contains the fol- 
lowing: Remarks on some remains of plants, Foraminifera and An- 
nelida, in the the Silurian rocks of Central Wales, by W. Keep- 
ing: six new plants, and Myrianites lapworthii, an annelid, are 
described. The Rev. A. Irving continues his notes on the Dy- 
assic and Triassic rocks, and Professor E. Hull answers some of his 
previous statements. The evidence of the angular drift in fa- 
vor of a great post-glacial flood is continued by Mr. H. H. Howorth, 
who asserts that the marine drift will lend him further support: 
— The December issue of the Geological Magazine contains: 
Notes on Oreaster bulbiferus, from the Upper Chalk of Kent, by 
P. Herbert Carpenter. A notice, the third in order, of fish re- 
mains from the Blackband Ironstone of Borough Lee, near Edin- 
burgh, by Dr. R. H. Traquair. Four selachians, a dipnoan and 
three ganoids, are described.—— The fallacy of the theory of the 
" Permanence of Continents,” by J. S. Gardner. Mr. Gardner main- 
tains that Mr. Wallace’s supposition that the chalk is a shallow wa- 
ter deposit, is untenable. In it no allowance was made for the loss 
of iron from the body of the chalk by crystallization, nor for the se- 
gregation of the silica into flints. The absence of Globigerina and 
almost all the cretaceous fossils from the decomposed coral mud 
of Oahù, shows that they were not deposited under the same con- 
ditions, It is also argued that oceanic islands could not have re- 
ceived their peculiar land-shells by an oceanic route. Mr. H.H. 
Howorth continues his voluminous argument uponthe “ Traces of 
a Great Post-glacial Flood.” C. Lapworth writes upon the iden- ` 
tification of certain beds near Birmingham, England, hitherto sup- 
Posed to be Upper Silurian, with the Cambrian era. W. Dames 
Sives some new facts upon the skull ot Archeopteryx. The open- 
mg called nasal, by Marsh, is preceded by a third opening, en- 
tirely surrounded by the premaxillary, and this opening is affirmed 
to be the true nasal aperture. The clearing away of the matrix 
from the skull examined (that in the Royal Mineralogical Museum 
of Prussia) showed the dentition, and proved that Marsh was in 
error in considering that the teeth were limited to the premaxillary, 
e they occur at least upon the anterior portion of the maxillary. 
| r. Dames also states that appearances are in favor of a separate 
kag for each tooth, rather. than of a groove, as stated by 
b a - The shoulder-girdle is not yet cleared from the matrix, 
gon to be different from anything known elsewhere. At 
Hi e meeting of the Geological Society of London Dr. R. 
ausler communicated the results of his researches on the arena- 
Sous fordminifera of the upper Jura of the Aargau—about sixty 
= are determined. r. J. E. Taylor gives proofs of the 
n Ance, along the shores of Norfolk and Suffolk, of an ex- 
~ YE sub-marine peat-bed, full of bones and teeth of elephant,
