208 The American Geologist. Marcii, 1894 
Dk. Johnston-Lavis, in referring to specimens and micro- 
scopic slides showing eozoonal structure in the ejected blocks 
of Monte Somma, exhibited by him, said that all the criti- 
cisms of Eozoon have so far been destructive, no analogous 
structure having been found in other localities under condi- 
tions that could explain the origin of so curious an arrange- 
ment of different minerals. These altered limestones from 
Monte Somma correspond in all details with those of the orig- 
inal Canadian specimens, and. in many cases, on account of 
their freshness, exhibit some of the pseudo-organic structural 
details, such as the stolon-tubes!, in far greater perfection than 
does the true so-called Eozoon canadense. He had been work- 
ing at the subject in conjunction with Mr. J. W. Gregory, F. G. 
S. Abs. of Proc. Geol. Soc. Lond. Wo. 610, Series of 1892-93. 
Sixth Annual Meeting of the Geological Society of 
America. 
I Concluded from pa^e 148 in the February number. J 
Further notes of the papers read at this meeting, held Dec. 
27-29, 1893, in Boston and Cambridge, Mass., are as follows : 
25. The Shasta-Chico series of the Pacific coast. J. S. Diller, 
Washington, D. C. Several measured sections of the Cretaceous were 
shown and compared with other sections in different parts of the same 
region. The stratigraphic and faunal continuity of the Shasta-Chico 
series, composed in California of the Knoxville, Horsetown, and Chico 
beds, was fully maintained. 
26. The Cretaceous faunas of the Shasta-Chico series. T.W.Stan- 
ton, Washington, D. C. The Cretaceous strata of the Sacramento val- 
ley belong to the Chico formation, the Horsetown beds, and the Knox- 
ville beds,— the last two constituting the Shasta formation. Until re- 
cently the Chico and the Shasta were supposed to be separated by 
stratigraphic and faunal breaks that indicated a considerable time 
hiatus between them. Later studies of the stratigraphy and larger 
collections of fossils have shown that these two formations are closely 
related, and the preliminary announcement that they form a continuous 
series was made by Messrs. Diller and Stanton at the Ottawa meeting 
of the Geological Society. The past season's field work has strength- 
ened the evidence of the continuity of the faunas. In studying many 
sections several distinct faunal zones characterized by certain species 
or associations of species were recognized, but in every case there was 
a commingling of species near the confines of the different divisions, so 
that no sharp line of demarcation could be drawn between them. 
21. Geology of Indian Territory and Texas adjacent to the Red 
River. Robert T. Hill, Washington, D. C. The region is very di- 
versified in later Mesozoic and Ceuozoic formations, and is where the 
distinct features of the diverse Appalachian, southern coastal plain, 
and Texan regions are differentiated. The Washita division of the 
Comanche series attains its greatest development here, while the Fred- 
ericksburg is represented only by a thin limestone formation. TheDeni- 
son beds, consisting of the Marietta, North Denison, Paw Paw, and Main 
Street, represent a littoral ferruginated group which thins out rapidly 
southward. 
The Red river flows in the Dakota sandstone from the Grayson county 
line eastward to Pine Bluff, and this formation is highly glauconitic
