in Rome, and has an old label, " Litharcea pxdvinata." It is, however, quite different from 

 Michelotti's figured type of L. ptdmnata (I. c.) which is not easy to understand : for while the 

 growth-form is that of a Goniopora, the striae running from calicle to calicle are not typical 

 of Goniopora ; cf., however, the calicles shown on PL IX. fig. 3. On the other hand, it should 

 be noted that Sismonda accepted Michelotti's figure as that of a true Litharcea ( = Goniopora) 

 and remarked on the large size of the calicles (Pal. Terrain Tert. Piemont, 1871, p. 26). 



The encrusting, almost primitive growth-form of the coral here described is very different 

 from that of Michelotti's figured type.

In addition to these : — 



Poritids said to be of the same " species " as that described and figured from (a) are 

 recorded from Enzesfeld in the Leithakalk in Austria; Rudelsdorf, near Landskron in 

 Bohemia, in the Tegel ; Mattersdorf in Hungary ; and at Kostel in Moravia. 



Poritids said to be of the same " species " as that described and figured from (c) are recorded 

 from Nodendorf, Porzteich, and in the Muschelberg near Nikolsburg in Moravia. 



Poritids said to be of the same " species " as that described and figured from (d) are recorded 

 from Potzleindorf, Grund, Enzesfeld, Niederleis, Nodendorf, Kalladorf, in Austria ; Mattersdorf 

 in Hungary ; Nikolsburg and Kostel in Moravia ; in the Leithakalk of St. Nicholai and Gamlitz 

 in Styria. 



A Poritid said to be of the same " species " as one of two described and figured from 

 (e) is recorded from Gradische, also near Oberburg. 



A Poritid said to be of the same " species " as one of the two described and figured 

 from (f) is recorded from Pfemyslan. 



There have thus been as many as 29 finds, mostly from separate localities, but we have 

 only nine descriptions, a result almost entirely due to the custom of " making species."
