around the fruit by a kind of frame looking like a part of a 

 destroyed envelope. Locality: Unknown. Specimens of the 

 true C. multistriatus have been found at Colchester. They are 

 broader but shorter than this described form, and do not have 

 any trace of the coaly envelope. 



Carpolithes Jacksonensis, Sp. nov. PI. 46, fig. 4. Fruit about 

 two inches long, one inch broad, ovate, oblong, pointed, marked 

 with six? elevated ribs. This species is not rare in coal No. 1 B. 

 It may be, perhaps, referable to Carpolithes sulcatus, Sternb., 

 though far different in general outline. Locality: Murphys- 

 boro, Jackson county. Lower Coal Measures. 



Carpolitlies cistula, Sp. nov. PL 46, fig. 5. (From a speci- 

 men in my cabinet, found at Murphy sboro.) This fruit, 

 which in general outline is about square-oblong, appears formed 

 of three parts: an outer, broad or thick envelope; a medial 

 one, apparently hard and thin, replaced in the specimen by a 

 thin coat of coaly matter; an inner kernel or fruit, elliptical, 

 inflated or convex, smooth and marked in the middle by an 

 irregular rib. 



Carpolithes fasciculatus, Sp. nov. PI. 46, fig. 7. Fruits gen- 

 erally flattened, smooth, oval, short-pedicelled, marked in the 

 middle by a short, narrow furrow. A common species, found 

 especially in the high coal. These fruits are generally three, 

 four or more together in close proximity, as if they had been 

 attached to a common pedicel or in bunches. I have never- 

 theless not been able to see them in a more evident connection 

 than in the specimen copied, fig. 7. Is plenty at Grayville, 

 White County ; Upper Coal Measures.
