Ulrich's genera are founded in many cases upon such indefinite char- 

 acters that the fact of a species being placed by him in another genus 

 does not militate against its being considered a synonym of some 

 species here regarded as Monticulipora . 



72. — M. Litvis Ulrich, 1882. 



Corrallum free or attached to some foreign substance, sub-globular 

 or irregular in outline ; surface smooth or with a few low and broad 

 monticules, occupied by cells a little larger than the average ; corallites 

 thin-walled in immature portion and crossed by straight or oblique 

 tabulae, a few of them with vesicles on one side; in mature portion 

 walls slightly thickened, with a larger number of vesicles and more 

 numerous straight tabulae ; tubes polygonal, the visceral chamber 

 crossed by a lamina excavated in a triangular or concentric manner; 

 small number of interstitial cells. (Jour. Cin. Soc. Nat. Hist., vol. 

 5, Dec. 1882, p. 236.) 



Locality.— Oxford, O. 



Re?narks. — This species, while differing in outward aspect from 

 M. consimilis Ulr ■. , (See No. 16 M. cincinnatiensis.) has exactly the 

 same internal structure. If separated it must be by the external form. 



73. — M. verrucosa n. sp. 



Corallum parasitic, forming patches of greater or less extent, the 

 edges being inclined to turn up; surface with small, conical monticules 

 about two mm. apart, more or less sub-solid at the apex and arranged 

 in diagonal intersecting rows; calices circular, about nine in two mm.; 

 interstitial cells present, more numerous in the monticules; internal 

 structure unknown. (Geol. Sur. Illinois, vol. 8, 1890, p. 418, as 

 Calloporella ? nodulosa. ) 



Locality. — Savannah, Ills. 



Remarks. — The name given by Mr. Ulrich, nodulosa, having 

 been applied to a species of Monticulipora, it becomes necessary on 

 the transfer of the species to this genus to give it a new name. There- 

 fore that given above is proposed. The original M. nodulosa is a 

 branching form, while this species is parasitic. 



74. — M. petechialis Nicholson, 1875. 



Corallum forming small circular patches, from less than one-half 

 a line to a line and one-half in diameter, attached parasitically to
