Wallace, Samuel J. On the " Geodes" of the Keokuk Formation, and the genus Bio- 

 palla. < Am. Journ. ScL, vol, xv, 3d ser.', pp. 366-370. 1878. 



The author takes the ground that the well-kno-wn geodes of the Keokuk Limestone (Suhcarhon- 

 iferous) are of organic origin— sponges ; for which he proposes the genus Biopalla, and describes 

 eight species from that formation.

lu this i)aper the author shows that Molluscan species are so distributed as to show the identity 

 of the following groups of strata as members of the great Laramie Group : Judith Elver beds, Fort 

 Union beds, Lignitic series of Eastern Colorado, Bitter Creek series of Southern "Wyoming, and the 

 ^ear Elver Valley series of "Western "Wyoming.

Tn this paper the author discusses the geographical and vertical range of the fossils of the LarOr 

 mie Group, besides other questions concerning its extent, geological age, &c.

miipsocephahts, Belleroplion, and Triplesia from the Potsdam Sandstone, showing an antiquity for 



these genera not hitherto known.

A six-page pamphlet has been received from the author, bearing the following title: 

 "Kent Scientific Institute. (Miscellaneous Papers IJ^o. 3.) Notes upon the FossU Remains of 

 the Lower Carboniferous Limestone exposed at Grand Eapids, Michigan. By E. A. Strong." 



It is without date or place of publication, and probably ought not to be regarded as regularly 

 published ; but it Is noticed here at the suggestion of those who think a work of this kind ought to 

 contain a notice of all printed matter relating to its subject, leaving the question of validity of pub- 

 lication to be settled by the practice of naturalists. The following species are described as new: 

 Cladodus irregularis, Phillipsia longispina, Nautilus elliptieus, N. kentensis, Allorisma elongata, and 

 A. quadrata.
