covered with small shallow polygonal cells, the stalk excepted, which is perfectly 

 smooth. 



Fig. 2 is a small fungites from the same place, of the same size with the 

 figure ; the top is convex, and thick set with minute circular cavities ; the stalk 

 tends to a conoid form, and is coarsely striated lengthways. 



Fig. 3 has a very deep cup-like cavity in it, the bottom of which is very finely 

 radiated ; the remaining part covered with small tubera, not unlike those that 

 sometimes are seen in the insides of flints and pebbles. Externally it is irregu- 

 larly cellular, but the stalk is striated. 



Fig. 4 is a very singular body, and the most remarkably shaped fungites I evar 

 saw, being exactly oval on one side, and flat on the other, without the least appear- 

 ance of stalk. The oval or lower part is reticulated with polygonal cells, like 

 fig. 1. The flat or upper part is striated semicircularly, the striae passing from 

 one side to the other, and then reverting. 



Fig. 5 he received out of Italy, under the name of lapis subluteus Veronensis 

 stellis majoribus. The surface is finely marked with star-like cells, which are 

 elegantly striated from their centre ; and their edges rise a little prominent. The 

 lower part of this stone is of a conoid shape, and irregularly indented with coarse 

 circular rugae. 



Fig. 6 was found at Coalbrooke-dale ; is of a white colour, and very smooth 

 both on the sides and top, without any appearance of striae : but what renders 

 this very singular, is the remarkable thinness, its greatest diameter not exceed- 

 ing the 8th of an inch. 



Fig. 7 was found at the top of one of the highest mountains in this county, 

 near Caer-gwrle, in a reddish loamy soil, with various other diluvian remains. 



It is of a conoid shape, but considerably incurvated ; the sides are striated 

 lengthways, and likewise circularly, but the circular striae are much less frequent 

 than the others. At the thicker end there appears to have been a deep cup-like 

 cavity, the greatest part of which had by some accident been destroyed, but what 

 remains is radiated with thin and very prominent ridges placed at equal distances 

 from each other. On one side is a small flat fungites. 



Fig. 8 is a fungites from Coalbrooke-dale, seemingly formed of 3 or 4 smaller, 

 inserted one into the other. It has the same cavity on the top as the former, 

 with a minute striated concha anomia in it. Fig. Q. This fungites is almost 

 straight ; has a small cup-like striated cavity on the upper end ; is encompassed 

 with prominent ridges on the sides ; and is striated lengthways. Fig. 10. This 

 species came from Piedmont, and differs fi-om all the rest. It may be called an 

 echinated fungites, having 6 orders of sharp-pointed studs running lengthways 

 from top to bottom, and between each order appear some very minute longitudi- 

 nal striae. The upper part, instead of a cavity, is composed of several thin la-
