126 MADREPORARIA. 



reach tlie centre ; pali six, small, equal, grain-like, not very distinct, and surrounding a small 

 columellar tubercle. 



With a lens the whole surface appears to be strewn with granules. 



This is another form which approaches Pontes in habit. But the septa are too numerous. 

 They do not reach the columella, at least along their uppermost edges. The pali rise distinct 

 from the ends of the septa. In the figure they are eight in number, not six as stated 

 in the description. 



A Poritid, apparently similar to this, hence called by Reuss by the same name 

 " nummulitica," was found at Gradische, also near Oberburg ; while the same " species " was 

 said * to occur in the Tertiaries of Vicenza (Monte Castellaro, Monte Grumi, and other places 

 round Castel Gomberto). 



Further, in a still later work (op. cit., xxix. (1869) p. 250) the same " species " was 

 extended to take in another form still, in spite of its showing differences in growth-form and 

 in the size of the calicles : see Goniopora Vicenza 4-.

Beseription. — Corallum (form unknown) probably " Lappig-astig." 



Calicles 2 • 5-3 mm. across, quite shallow, hardly depressed. Walls often thread-like and 

 wavy, hardly traceable and often incomplete. 



Septa 18-20, irregular, crowded and fusing together in pairs and triplets, also united by 

 synapticuliB ; none are seen to end freely, all either fuse together or run into the large central 

 tangle. The interseptal loculi are small. 



This form is very distinct from the other Goniopora found in the same locality (see last 

 heading) ; only in growth-foim does it seem to correspond, but both are u-regular fragments 

 which tell little about the original shape. Reuss speaks of it as being probably "lappig-astig."

Description. — Corallum forms irregular rounded masses, often nearly globular, from 

 3-15 cm. in diameter, with edges at somewhat regular distances round the often tall and 

 gradually thickening base, round which fragments of epitheca occur.
