Megalonyx Laqueatus. 45 



ing a fossil supposed by Mr. Eaton to be a petrified crolalus. On 

 the contrary, he told Mr. E., that he thought it a plant, and in 

 writing to Dr. Torrey shortly after, mentioned that it was a 

 plant of the family Lycopo diaceae. It never entered into his mind 

 to refer it to Arundo, which belongs to a very different tribe of plants. 



This public denial has been rendered necessary by the follow- 

 ing passage of Silliman's Journal, at page 173, in the number 

 above alluded to. 



" One of our most accurate devotees to the study of recent 

 organic relics, William Cooper, Esq. of the New York Lyceum, 

 has examined it. He is in doubt, but is inclined to believe it an 

 arundo, or some plant of that family. Editor." 



Megalonyx Laqueatus. — Dr. Harlan read a paper, March 8, 

 1831, before the Academy of Natural Sciences of Philadelphia, 

 descriptive of the fossil bones of a new species of the megalonyx, 

 discovered in White cave, Kentucky. 



The bones of the megalonyx Jeffersonei, were discovered in 

 1796, buried two or three (eet beneath the surface of a cave in 

 Green Briar county, Virginia. Those of the megalonyx la- 

 queatus, now described, were found on the surface of the floor of 

 White cave. They consist of two claws of the fore feet ; a 

 radius, humerus, scapula, one rib, and several fragments ; the 

 oscalcis, tibia, a portion of the femur ; four dorsal, and one lum- 

 bar vertebra ; a portion of a molar tooth, from the fluted appear- 

 ance of wliich the specific appellation, (laqueatus,) is derived. 

 Dr. Harlan has illustrated his paper with three lithographic en- 

 gravings. 



On the same evening, Dr. Harlan read a paper descriptive of 

 an extinct species of fossil vegetable of the family Fucoides. This 

 paper, with a lithographic engraving, is published with the pre- 

 ceding one in the Transactions of the Academy of Natural 

 Sciences of Philadelphia. The fossil appears to have been im- 

 bedded in the millstone-grit formation : is singularly beautiful, 

 and has been named by Dr. Harlan, " Fucoides AUeghaniensis."
