513 



This species differs from Galeopsis vernicosa in its much smaller spiramen 

 and in its narrower zooecia. 



It differs from Galeopsis ennaceus in its spiramen much smaller than the 

 peristomice and in the greater length of the peristomie (=0.45 mm.). 



Occurrence. Middle Jacksonian (Castle Hayne limestone) : Wilmington, 

 Xorth Carolina (very rare).

Description. The zoarium is unilamellar, incrusting algae or shells. The 

 zooecia are elongated, distinct, elliptical, or oval; the frontal is very convex and 

 ornamented with numerous salient and pointed wartlike nodes. The apertura, 

 hidden at the base of the peristomie, is formed of a large anter and of a somewhat 

 smaller poster separated by two cardelles; the peristomice is orbicular; the peri- 

 stomie is recumbent on the distal zooecia; the peristome is thin, sharp, and often 

 bears a small, triangular avicularium with pivot. The ovicell is hyperstomial; it 

 opens largely into the peristomie. The spiramen is immense, salient, elliptical and 

 transverse.
