the pedicle was attached. It is possible that it might be the young 

 of P. Darwini, but at present I think it is a distinct species. 



Found associated with P. Danvini, about two miles south of Mays- 

 ville, Kentucky, but not found at Cincinnati, nor elsewhere, so lar as 

 yet known to me.

 Is so for separated from G. Di/eri, that it should be regarded as a 

 good species. It is treated as only a variety of G. Dyeri in the "Ohio 

 Paleontology," page 34, though Prof. INIeek says that it is quite possible 

 that it may be a distinct species. It is undoubtedly farther separated 

 from G. Dyeri than the latter is from G. decadactyhis, and had Prof. 

 Meek had other specimens before him it is more than likely he would 

 have treated it as a distinct species.

" Animal social, inhabiting a calcareous (?) tube, attached in clus- 

 tered masses to some solid body. The tube conical, slightly curved,

 of short imbricated rings, but apparently destitute of any cellular
