short acuminate spire having incurved slopes, its length being 
about one-quarter of the entire length of the shell, or that of 
the body whorl. Whorls largely concealed. Surface convex, 
sutures impressed; body whorl very high, somewhat abruptly 
convex near the suture where the surface of the penulti- 
mate whorl is overlapped for 4-5 of its width. | Non-umbilicate 
but with the columellar lip well defined and slightly twisted; 
aperture entire, outer lip but slightly thickened. Surface smooth, 
shining, bearing only fine concentric lines. Internal cast smooth. 
Dimensions: Height 22 mm.; width across body whorl 17 
mm. ; height of body whorl 18 mm. 
Locality: Agoniatite limestone, Manlius. This very pretty 
species has been found by Prin. John D. Wilson of Syracuse, 
who has considerately presented the type specimen to the state 
museum. It is unlike any species known from the New York 
Devonic in its short, concave spire and very large body whorl, 
features which also distinguish it from other forms of the 
genus.” 
The above views of Macrochilina onondagaensis, which were printed in 
Museum Bulletin No. 49, were furnished to the Academy through the courtesy 
of state paleontologist, J. M. Clarke. 
The cephalopoda are large, numerous, and interesting. Ago- 
niatitites expansus and Orthoceras marcellense are the most com- 
mon. Goniatites discoideus, Nautilus discites, Orthoceras con- 
strictum, Gomphoceras fischeri, Gomphoceras solidum, and Gyro- 
ceras transversum are not so abundant, though occasional speci- 
mens of all these may be counted on. 
Thoracoceras wilsoni is a new cephalopod named and de- 
scribed by Dr. John M. Clarke in museum bulletin No. 49, page 
126, as follows 
“ Thoracoceras wilsoni, sp. nov. The shell has a slight cyr- 
toceran curvature, notable chiefly in the distal apertural region.
