Say on Shells, &c. 325) 
Fossil in different parts of the U. States, particularly at 
the falls of the Ohio river and in Ulster County, New-York. 
From this last locality, Mr. C. W. Peale obtained some fine 
specimens when digging for bones of the Mastodon.—Has 
not yet occurred in “the alluvial deposit of New-Jersey. 
Each tube is divided into numerous cells by transverse 
septe, precisely as in the Favosite. Mr. Parkinson, in his 
Organic Remains 2, p. 21. remarks, that minute openings 
are observable in the sides of the tubes; these are not dis- 
tinct in the specimen under examination, owing perhaps to 
its being entirely silecified, though an equivocal appearance 
justifies “the belief of their having existed ; and if so, the 
analogy is very strong with the Favosites. A species of 
Turbinolia is implanted in the specimen under examination. 
Pentacrinus caput—Meduse. 
Of this very remarkable and rare animal, a specimen oc- | 
curs in the collection of the Museum of South Carolina ; it 
was brought from the Island of Gaudaloupe by Mr. L’Her- 
menier. This is, 1 believe, the fourth recent specimen 
known, of this family of extinct animals: of the two other 
individuals one is in the French, and the others in British 
collections. 
The well known fossil amimal supposed to be of this fam- 
ily, so common near Huntsville and in some parts of Ken- 
tucky, and which has been figured and described by Par- 
kinson, cannot be properly arranged under either of the 
genera. ‘These vary in form and size. I have seen four 
very distinct varieties, but it is possible they may have be- 
longed to different paris of the same pedicel. 
Although this fossil is familiar to the observation of Natur- 
alists, yet it does not appear that any particular name has 
been appropriated to it, or that it has been assigned to any 
definitive place in the systems. 
From its peculiar appearance, persons who have not de- 
voted their attention, to the affinities of natural objects, have . 
regarded it as a petrified nut or Althea bud, and from the 
ambiguity of its characters, or the obliteration of its sculp- 
ture, naturalists have hesitated to indicate its family, or kin- 
dred generic group. 
Parkinson is the first author who has figured and descri- 
bed this animal remain. He refers it to the genus Ener-
