Plate 136, figs. 1-3. 



Description. The zoarium incrusts bryozoa and shells, forming very irregu- 

 lar polygons. The tubes are oval, wide, wrinkled transversally, of quite variable 

 width. The peristome is thin, salient, orbicular. 



Diameter of tube 0.40 mm. 



Lengtlrof tube 0.60-1.20 mm. 



Diameter of peristome 0.22 mm. 



This species is well characterized by its great zooecial width. The specific 

 name is in honor of Dr. J. H. Pratt, State geologist of North Carolina. 



Occurrence.- Middle Jacksonian : Wilmington, North Carolina (common) ; 

 near Lenuds Ferry, South Carolina (rare) ; 3J miles south of Perry. Georgia

STOMATOPORA STRIATULA, new species. 



Plate 116, figs. 4, 5. 



Description. The zoarium incrusts shells, orbitoid foraminifera and bryozoa ; 

 the angle of dichotomization is very acute and about 00 at the most. The tubes 

 are oval, wide, striated transversally. The peristome is thin, salient, orbicular, 

 The peristomie is short. The angle of divergence is sometimes so small that two 

 priiuoserial tubes are adjacent and the zoarium partially assumes the aspect of a 

 Proboscina.
