TEEMATOPORA, HalL 



Teematopora scutulata, n. sp. 

 Ramose, solid ; branches widely diverging; diameter .66 mm. ; cells 

 tubular cylindrical ; apertures oval, margins parallel with surface ; 

 length .25 mm., arranged in longitudinal parallel rows and oblique 

 transverse rows; oblique arrangement most conspicuous; at the base 

 of each aperture is a strong node or spine, longitudinal rows sepa- 

 rated by ridges; ridges coalescing between apertures, giving to the

Trematopora poltgona, n. sp. 

 Ramose, solid; branches widely diverging; diameter 1.25 mm.; 

 cells tubular; apertures oval, very closely arranged ; space between 

 them narrow, elevated, angular, appearing as walls of cells, making 

 the apertures apparently polygonal ; length .40 mm., width .25 mm.; 

 at each angle a conical node, the elevations frequently granulose.

 Ramose; branches distant; diameter .60 mm., frequently sinuous ; 

 cells tubular, sub-cylindrical ; apertures oval ; length .25 mm., width 

 .12 mm., arranged in longitudinal rows, alternating and forming ob-
