Figs. 1-5. Cupularia doma D’Orbigny, 1851. (See also plate 1, fig. 18.) (p. 77.) 
1. A zoarium, X 10, showing the ancestrular zooecia covering the substratum. These zooecia 
are calcified and deprived of polypide. 
2. Another zoarium X 10, illustrating that the ancestrular zooecia are easily detached in fossiliza- 
tion. 
3. Inner side of zoarium, X 10, which is smooth or slightly granulated. 
4. Inner (superior) side of a zoarium with hydrostatic zooecia, X 20. The ribs are smoooth and 
are not radially arranged. This difference in arrangement depends on the form of the substratum 
on which the larva fixes itself. 
5. Celluliferous face X 20, illustrating the form of the denticles. 
Miocene (Duplin marl): Wilmington, North Carolina. 
Figs. 6-10. Cupularia denticulata Conrad, 1841. (p. 79.) 
6. Calcified ancestrular zooecia X 20. The vibracula alone are visible. 
7. Center of a zoarium X 20, deprived of calcified zooecia. 
8. Inner side of a large zoarium X 20, without hydrostatic zooecia, showing the regular bifurca¬ 
tion of each rib. 
9. Zooecia X 20, illustrating the two symmetrical condyles and the vestibular arch above, the 
auriculated vibracula and the irregular denticles below. 
10. A median section through a zoarium X 25, showing the substratum (s) upon which the larva 
became attached, the calcified hydrostatic zooecia (zh) covering the substratum and the ordinary 
zooecia surmounted by their vibracula (v). 
Pliocene (Waccamaw marl): Waccamaw Iliver, Horry County, South Carolina. 
Fig. 11. Cribrilina punctata Hassall, 1841. (p. 87.) 
The type specimen of Lepralia marylandica Ulrich and Bassler, 1904, X 20, showing its identity 
with this widespread fossil and recent species. 
Miocene (St. Mary’s formation): Cove Point, Maryland. 
Fig. 12. Puellina radiata forma scripta Reuss, 1847. (See also pi. 35, fig. 1.) (p. 89.) 
A well-preserved example, X 20 with wide zooecia, somewhat approaching forma rarecosta, 
Reuss, 1847. 
Miocene (Yorktown formation): 1 mile west of Fort Nonsense, Gloucester County, Virginia. 
Fig. 13. Puellina innominata Couch, 1844. (p. 90.) 
A Miocene example of this widespread species, X 20. 
Miocene (Choctawhatchee marl): Jackson Bluff, Ocklocknee River, 25 miles southwest of Talla¬ 
hassee, Florida. 
Fig. 14. Cribrilina ligulata, new species, (p. 88.) . 
The type specimen, X 25, showing the ancestrula and surrounding zooecia. The spines of the 
peristome are transformed by coalescence into several small tongues. 
Miocene (Calvert formation): 1 mile south of Parkers Creek, Calvert County, Maryland. 
Fig. 15. Cribrilina cuspidate, new species, (p. 88.) 
The incrusting type specimen, X 20 showing the line of small lacunae, the few large lacunae 
and the very large triangular avicularia with rounded beak. 
Miocene: Santiago, Cuba.
