. CyatJllIOrnilS _ /2 xMs species, originally figured on Plate 



25 of Vol. I, Paleontology of New-York, was too obscure in its intimate 

 structure to be referred satisfactorily to any known genus. At a later period 

 (1850), I determined it to be generically identical with a species occurring in 

 the Leadbearing limestone of Wisconsin and Iowa, which was subsequently 

 figured and described by Dr. D. D.Owen under the name Selenoides (S. 

 ioivensis ) ,- being referred by him to the Foraminifera, and related to the 

 Orhitulina or Orbitoidcs. Should this genus proA^e distinct from Recepta- 

 culites, to which I had referred the western specimens, the species above 

 will be recorded as Selenoides cyathiformis. 



Very recently Mr, Salter has advanced the opinion that the Receptacu- 

 liies belongs to the Foraminifera, and is related to the Orbitolites, without 

 apparently having known of this suggestion of Dr. Owen in regard to an 

 allied or identical generic form. 



* Mr. Salter lias more recently proposed the name Ctenodonta for the species in- 

 cluded under this genus, on account of the inappropriateness or erroneous signification 

 of the name Tellinomya; the hinge-line being crenulate, and the species not at all 

 related to Tellina or My a. The name was originally given from the external form; and 

 so soon as I obtained the means to do so, I illustrated the hinge-structure. I retain 

 the name Tellinomya. according to the usage of naturalists.
