Genus TROCHILIOPORA Gregory, 1909 



TROCHILIOPORA (?) BARTSCHI, new species 



Plate 90, figs. 4-9 



Description. — The zoarium is free, conical, orbicular, or cordiform. 

 The tubes are large, arranged in very irregular radial series; the 

 peristome is thin, orbicular. The concave center, the interlinear 

 spaces and the peduncle are covered with polygonal mesopores (?) 

 closed by a calcareous pellicle. There are some tubes disseminated 

 on the peduncle. 



Measurements. — Height of zoarium, 3.00 mm.; diameter of zoarium, 

 3.00 mm.; diameter of peristome, 0.20 mm. 



Affinities. — This curious species approaches the species of the 

 Cretaceous genus Trochiliopora Gregory, 1909, from which it differs 

 only in the presence of the tubes on the peduncle. Without thin 

 sections we cannot classify the species properly but it is interesting 

 to note the persistence of the fossil forms in the tropical zone. The 

 specific name is in honor of Dr. Paul Bartsch.
