514 BULLETIN 106, UNITED STATES NATIONAL MUSEUM. 



Affinities. This species much resembles Galcopsix crmaceus. It differs from it 

 in its greater zooecial length (greater than 0.60 mm.) and in its spiramen which 

 has not the form of a transversal slit. 



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

 North Carolina (rare).

GALEOPSIS ERINACEUS. new species. 



Plate 66, fig. 2. 



Description. The zoarium incrusts shells. The zoopcia are elongated, distinct, 

 elliptical, little regular; the frontal is convex and bristles with small points. The, 

 apertura hidden at the bottom of the peristomie has two cardelles placed a little, 

 low ; the peristomice is orbicular ; the peristome is thin, salient, irregular, notched ; 

 the peristomie is recumbent on the distal zooecia. The spiramen is very large, 

 transverse, elliptical, salient, much wider than the peristomice.

Affinities. This species is quite well characterized by its spiramen in the form 

 of an elongated and narrow slit. It differs in addition from Galeopsis verrucosa 

 in its smaller micrometric dimensions.

GALEOPSIS CYCLOPS, new species. 



Plate 66, figs. 4, 5. 



Description. The zoarium incrusts shells. The zooecia are elongated, distinct, 

 fusiform, or cylindrical; the frontal is a little convex and formed of a tremocyst 

 with much scattered pores. The peristome is salient, thin; it bears distally a small 

 round amculariwm without pivot; the peristomice is orbicular; the peristomie is 

 quite oblique and is recumbent on the distal zooecium. The spiramen is large. 

 orbicular, not salient, smaller then the peristomice.

Variations. The young zooecia have no spiramen; it is replaced by a deep 

 sinus of the peristome as in the Stomachetosellidae (fig 4). The ancestrula (fig. 

 5) is an ordinary zooecium. 



Affinities. This species much resembles Escliara heterostoma Keuss, 1869, of 

 the Priabonian from the Vicentin. It differs from it in its incrusting and not 

 escharian zoarium and in the presence of the small distal avicularia.
