think are sufficient to warrant the adoption of a distinct name. Mr. Conrad 
originally considered the fossil forms as the same as the living ones, and so 
gives it in his Miocene fossils. But in his list of Miocene fossils given in 
the Proceedings of the Academy of Natural Sciences, Philadelphia, for 1862, 
he appears to drop the name Nucula limatula and use that of Yoldia levis 
instead, and is followed by Mr. F. B. Meek, in the Smithsonian Institution 
check list, and I do not find any explanation of the change anywhere given, 
so presume they had considered all the fossil forms as distinct from the N. 
( Yoldia) limatula as now existing, which I do not consider as correct. 
The species, as found in New Jersey, attain a length of rather more 
than 1 inch and differs from the living ones only in the features above 
mentioned. 
Localities: I have seen small specimens of it from near Jericho and 
Shiloh, Cumberland County, N. J. The figured example, with some others, 
are from the collection of the Academy of Natural Sciences, Philadelphia, 
and are contained in a greenish-gray marl, resembling that from near Shiloh. 
But there is no positive evidence that they are from Shiloh, other than a 
fragment of newspaper in the tray, with the pencil mark “Shiloh, 'T. A.C,” 
which has not been copied on the label used for the specimen, that bearing 
only the mark “N. J.”
