92 PROCEEDINGS OF THE ACADEMY OF 



at Plymouth, Cape Cod, and near Islip, Long Island, and was first discovered at 

 Cedar Bridge by Prof. S. W. Conrad. This locality was visited by Dr. Torrey, 

 about 1835, and carefully indicated by him in Ann. N. Y. Lye. Nat. Hist, iv 

 83 — so that there was no difBculty in finding the precise points mentioned ; but 

 Mr. R. was sorry that no trace of the plant could now be found there, and it 

 has doubtless been eradicated by animals or by unscrupulous collectors, or 

 has been otherwise unable to maintain its foothold in " the struggle for exis- 

 tence." The vicinity was also carefully examined, but without success. The 

 plant is said to have once existed near Peraberton Mills, N. J., but as that 

 neighborhood is now entirely under cultivation, there is no evidence that the 

 Corema Conradii now exists south of Long Island. If it is again to be dis- 

 covered in New Jersey, it will probably be in the wide sandy waste a few miles 

 west of Cedar Bridge, near the boundary between Burlington and Ocean coun- 

 ties, where a succession of elevated ancient ocean beaches offer conditions 

 similar to those of Cape Cod. 



Prof. Cope exhibited bones and teeth of the large extinct Chinchilla of the 

 island of Anguilla, W. I., Amblyrhiza i nun data, and with them teeth of 

 a second and new species, which he called Loxomylus 1 o ngid en s. It was 

 also allied to the Chinchillas, and of large size. They were accompanied by 

 a shell implement of human manufacture, which was, so far as discover}' in 

 an earthy matrix, and the color, etc., were evidence, of the same age as the 

 Rodents.
