Affinities. — This species much resembles Galeopsis erinaceus. It differs from it 
in its greater zooecial length (greater than 0.60 mm.) and in its spirameri which 
lias not the form of a transversal slit. 
Occurrence. — Middle Jacksonian (Castle Hayne. limestone) : Wilmington, 
North Carolina (rare). 
Holotype.— Cat. No. 64162, T7.S.N.M. 
GALEOPSIS ERINACEUS. new species. 
Plate 6G, fig. 2. 
Description. — The zoarium incrusts shells. The zooecia 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. 
Occurrence . — Middle Jacksonian (Castle Hayne limestone): Wilmington, 
North Carolina (rare). 
Holotype. — Cat. No. 64161, U.S.N.M. 
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 tremocvst 
with much scattered pores. The peristome is salient, thin; it bears distally a small 
round avicularium 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. 
Measurements. — •Peristomice

Zooecia 
[ T.s=0.45-0.50 mm. 
! 13=0.25 mm. 
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 (tig. 
5) is an ordinary zooecium. 
Affinities. — This species much resembles Eschara heterost.oma Reuss, 1869, of 
the Priabonian from the Vicentin. It differs from it in its incrusting and not 
escliarian zoarium and in the presence of the small distal avicularia.
