Among the types were species of Cladodus, Oracanthus,’ Ctenacan- 
thus, Stettacanthus, Asteroptychius, Dactylodus,|Deltodus, Sandalodus, 
Psephodus, Heliodus, Ctenodus. Dinichthys corrugatus|was taken as a 
type of a new genus Stenognathus. 
At the conclusion of the papers, an election of sectional officers was 
held. Prof. E. B. Wilson was elected chairman for thefensuing year,

New York Academy of Sciences.—Section of Geology.— 
March 15, 1897.—The first communication of the evening was by Mr. 
Hienrich Ries entitled “ Mineralogical Notes.” Mr. Ries spoke of some 
Allanite crystals with new faces ; also of some large crystals of fibrous 
gypsum from Newcastle, Wyoming; also exhibited some large Children- 
ite crystals from Maine and some Amphibole crystals with many 
terminal faces from Virginia. He also spoke of some Pseudomorphs of 
gold after Sylvenite from Cripple Creek, Colorado, The finding of a 
new Beryl crystal with an unusually large number‘of terminal faces in 
New York City was also noted. 
The second paper of the evening was written by! Mr.}Herbert Bolton, 
entitled “ The Lancashire Coal Field of England ” and read in abstract 
by President Stevenson. The paper spoke of the geographic conditions 
of the Lancashire voal field and its neighborhood, of the extent and 
quality of the coal and of the age of the structural movements which 
had caused the present geological characteristics in the coal area. A 
careful correlation was made between the coal measures of this field 
and the deposits of the United States. Distribution of the fauna and 
flora and their character was taken up in some detail and it was shown 
that in the lower coal measures the life is mostlytmarine, in the middle 
coal measures of fresh and brackish origin, and in the upper coal 
measures that the fauna was scarce. When published this paper will 
be a valuable contribution to the literature of coals and will be of great 
assistance to workers in America in their endeavors to correlate the 
deposits on the two side of the water. 
The third paper of the evening was by Stuart Weller, of Chicago 
University, entitled “The Batesville Sandstone of Arkansas,” ab- 
stracted by Mr. Gilbert Van Ingen. The paper entered into some 
detail regarding the Batesville section and the fauna of the Batesville 
sandstone in that section. Of the invertebrates thirty species have been 
found, of which eleven point to the St. Louis age of the sandstone, six 
to the Kaskaskia age, while thirteen are of indeterminate value. On 
account of the greater abundance of the numbers of specimens of the
