122 MADREPORARIA. 



in Rome, and has an old label, " Litharma pidvinnta!' It is, however, quite different from 

 Michelotti's figiu'ed type of L. pulvinata {I. c.) which is not easy to understand : for while the 

 growth-form is that of a Goniopora, the strise 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 Lithanm. ( = Goniopora) 

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



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

 from that of Michelotti's figured type.

 Containing notices of Poritids, many of which were certainly Goniopora;, from the following localities. 



Specimens described and figured from — 



(a) Potzleindorf, Vienna. , («) Neustift, near Oberburg, Styria (2

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, KaUadorf, in Austria ; Mattersdorf 

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

 in Styria. 



A Poritid said to he 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 (/) is recorded from Pf emyslan. 



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."
