Plate 40. 
Figs. 1-4. Tubucellaria punctulata Gabb and Horn, 1862. (p. 170.) 
1. Zoarial fragments, natural size. 
2. A ramified segment, X 20. 
3. Another segment, X 20, illustrating the zooecial surface. 
4. Longitudinal section, X 20. 
Pleistocene: Santa Barbara, California. 
Figs. 5, 6. Tubucellaria punctulata, var. minor, new variety, (p. 170.) 
A fragment natural size, and surface of the same, X 20. The smaller size of the zooecia and 
tremopores is evident. 
Pleistocene: Santa Barbara, California. 
Fig. 7. Lagenipora spinulosa Hincks, 1884. (p. 171.) 
An example, X 20, much changed by fossilization. 
Pleistocene. Dead Mans Island, off San Pedro, California. 
Figs. 8, 9. Eoloporella umbonata, new species, (p. 178.) 
8. Zooecial surface, X 20, illustrating the areolar pores. 
9. Well-developed example with interareolar costules radiating from the umbo. Several ovi- 
celled zooecia are present. 
Pleistocene: Santa Barbara, California. 
Figs. 10, 11. Schismopora abrupta, new species, (p. 180.) 
10. Surface of the incrusting zoarium, X 20, with some of the usual small avicularia transformed 
into very long ones. 
11 Another surface, X 20. The transverse, smooth, deeply embedded ovicell and the numerous 
small triangular avicularia are quite visible. 
Pleistocene: Santa Barbara, California. 
Figs. 12-15. Schismopora lanceolata, new species, (p. 181.) 
12. The small lamellar zoarial masses, natural size. 
13. Surface, X 20, illustrating the triangular sinus of the apertura and the lanceolate interzooecial 
avicularia. 
14. Ovicelletl zooecia, X 20. The characteristic avicularia are also present. 
15. Portion of the zooecial surface, X 20, showing the incomplete zooecia. 
Pleistocene: Santa Monica, California.
