This species was found in the Upper Coal Measures of Poteau mountain, 

 Indian Territory, and one very closely resembling it, if not identical, 

 was found in the Boone Chert, Lower Carboniferous, at several places 

 in northwestern Arkansas.

This Bryozoan is common and characteristic in the Upper Coal 

 Measures of Nebraska, and is found in the same horizon in Utah and 

 Arizona, and was also found in the Upper Coal Measures of Poteau 

 mountain, Indian Territory. The same, or a very similar species, occurs 

 in the Boone Chert, Lower Carboniferous, of northern Arkansas.

This species is common in the Upper Coal Measures, or Permo-Car- 

 boniferous, of Nebraska and Kansas, and in the true Coal Measures of 

 Illinois, and in the Upper Carboniferous of Arizona. It has also been 

 found in the Chester and the St. Louis Limestone, Lower Carbonif- 

 Bjfous, of Illinois. Waagen * says that the true genus SynoclaOia has 

 not been found in America, and that in Europe or Asia it is characteris- 

 tic of the Permian. He refers the American forms to the genus Sep- 

 topora of Prout.

A single specimen was found in the Upper Coal Measures of Poteau 

 mountain, Indian Territory ; it agrees best with Dr. C. A. White's- 

 figures. The species is of frequent occurrence in the Upper Coal 

 Measures of Iowa, Nebraska, Kansas, Illinois, Texas and in the Uppei-
