Fig. 2 represents a portion of a spike of seed-vessels 

 found associated with Fig. 1, and which may possibly have 

 been the female flowers of the same plant; the detached 

 capsules would be included in the genus Cardiocarpon. 



Fig. 3. A different species of 

 Fig. 2, or the same at a different 

 stage of maturity. Its resem- 

 blance to AntJiolithes Pit- 

 cairniae (L. & H., Tab. 32,) will 

 strike every one; indeed it only 

 differs from the figure of Lind- 

 ley & Hutton in the absence of 

 the long awn-like appendages 

 which form so striking a feature 

 in A. Pitoairniae. 



All these fossils are found Fig. 2. FigTs. 



associated with the lowest stratum of coal in the coal basin 

 of Ohio. 



NEW LOCALITY OF LIMNEA MEGASOMA OF SAY. 



BY PROF. J. P. KIRTLAND. 



Read before the Cleveland Academy of Natural Science, November 21, 1853. 



By the kindness of J. A. Floom, M. D., of Stark county, 

 Ohio, I am enabled to lay before the society a fine specimen 

 of this rare shell, obtained by him "in lagoons along the 

 Mahoning river, near Alliance," in the aforementioned 

 county. This shell has never before been observed in this 

 State, and has only been met with in some small lakes 

 south of Lake Superior, and in a swamp near Burlington, 

 Vermont.
