200 EOOEl^E AND LOWER OLIGOCENE CORAL FAUNAS. 



This species is known to me only througli the above description and 

 Lonsdale's accoiiipanying tig-ure, which is here reproduced. The figured 

 specimen is in the collection of the Geological Society of London; in same 

 matrix as the Flahellum ctineiforme. The species is based on undeterminable 

 material, so the species must lapse.

Several woru casts, possibly fragments of a Deudropliyllia, claimed a notice, 

 though their generic determination could not be ascertained. They were slightly con- 

 ical or cylindrical, the lower termination not unfreiiuently preserved, presenting the 

 same character as that of the lateral shoots of DeiKh-ophyllia Itvi-is. The specimens 

 had nearly uniform diameter of half an inch at the upper extremity; and the greatest 

 length was about an inch. The characters of the lamella', so far as they could be 

 ascertained, agreed with those of l)endro|)hyllia, and in the reticulated structure of 

 the very partially preserved exterior, as well as in the mode of union with the lamellse, 

 there are still further agreements. In these particulars a resemblance also with the 

 Alabama coral Endopachys alatum existed, but in no instance was a trace of a pedicel 

 detected, nor any indication of a surface which had once been attached.

" Corallum not cellular, but in layers like the coats of an onion; 

 branches anastomosing; central axial star having distant septa Ijetween the 



lamellfe."

"Corallum minutely granulated, suboval, sides faintly marked with 

 vermicular lines; calices round, not very prominent, unequall}- distributed, 

 proximate or remote; lamellas minutely serrate."

2 Felix, in the Zeitscbr. Deutsch. geol. Gesell., Vol. XXXVII, 1885, pp. 397-100, proposes the 

 generic name "Petrophyllia" for Motilliraidtia i/vumi CatuUo S|i. of Kouss aud d'Achiardi, from Monte 

 Griimi, Jlontecchio Maggiore, vtv., Italy. As tlin name Petrophyllia had been previously used by 

 Conrad for a different genus of corals, " Petrophyllia " Felix must be replaced by another name.
