DESCRIPTION OF FOSSILS 513 



middle, irregularly ribbed, surface quite uneven and smooth. Length 

 25 millimeters, width 20 millimeters, thickness 14 millimeters. 



Genus Hicoroides, Perkins, Vermont Report, 1903-1904, page 183. 



There are some fruits which in many respects resemble those of Hicoria, 

 but as there are important differences, it has seemed best to make the 

 above genus to include them. They are not large, none being above 

 medium size. The general form is triangular, pointed above; one side is 

 nearly flat, the other more or less convex, often strongly so ; open by a 

 single valve, which is usually on the flat side, but in some it is on the 

 convex side. The surface is ribbed with thin, sharp elevations extending 

 from end to end. In most cases the width is greater than the length. 



Hicoroides ellipsoidea, Perkins, Vermont Report, 1903-1904, page 184. 



Plate 87, figure 26. 



This species is one of the few in which the valve opens on the convex 

 side, as shown in the figure. It is strongly globular or ellipsoidal, longi- 

 tudinally and irregularly ribbed. Length 20 millimeters, width 23 milli- 

 meters, thickness 13 millimeters. 



Hicoroides aagtdata, Perkins, Vermont Report, 1903-1904. page 183. 



Plate 87, figure 27. 



This species is less globular than the preceding and somewhat smaller. 

 As the figure well shows, the valve is on the flat or. in this case, concave 

 side. The opposite surface is evenly and plainly ribbed. One edge, the 

 right hand in the figure, is much thicker than the other and otherwise 

 unlike it. Length 20 millimeters, width 20 millimeters. 



Genus Brandonia, Perkins, Vermont Report, 1903-1904, page 192. 



This genus has been created to include certain specimens which seem 

 to be quite different from most of those found in the lignite.

This appears to have been of a spongy texture. There is no central 

 cavity evident. In fact it is not unlike some of the globular galls so often 

 found on oak leaves, and further study may show it to be of this nature 

 rather than a fruit. It has become irregular in drying, but it is globular 

 in form, with a diameter of 22 millimeters.
