SYNOPSIS OF GENERA. 
xviii 
crests. Cells tubular, without septa. Intercellular structure vesiculose near 
the base, septate above. 
Example: Phractopora cristata , pi. xxi, figs. 36, 37. 
Fistulipora, McCoy (Ann. and Mag. of Nat. Hist., vol. Ill, p. 130. 1849). 
[Type, Fistulipora minor, McCoy A] 
Zoarium lamellate or massive, free or incrusting, sometimes ramose, hollow. 
Cells tubular, septate or non-septate. Interapertural space occupied by angular 
pits. Intercellular tissue composed of vesicles, sometimes irregularly disposed, 
at other times regularity superimposed, resembling septate tubuli. 
Examples: Fistulipora intercellata, pi. xxxii, figs. 15-20. 
Fistulipora confertipora , pi. lviii, figs. 1-5. 
Favicella, n. g. [Type, Thallostigma inclusa, Hall.] 
Zoarium free or incrusting, consisting of a thin expansion. Apertures inclosed 
in regular potygonal vestibular areas, similar to Selenopora. Surface between 
the apertures and ridges occupied by minute mesopores. Intercellular structure 
vesiculose. This genus bears the same relation to Fistulipora, that the forms 
included under Selenopora bear to Liciienalia. 
Example: Favicella inclusa, pi. lviii, figs. 21, 22. 
Ceramopora, Hall (Pal. N. Y., vol. ii, p. 168. 1852). 
[Type, Ceramopora imbricata, Hall.] 
Zoarium usually incrusting. Cells angular, radiating from one or more 
centers. Apertures angular, with the posterior margin usually elevated, giving 
to them an imbricating appearance. 
Examples: Ceramopora maculata , pi. xvi, figs. 5-11. 
Ceramopora labeculoidea, pi. xvi, figs. 1, 2. 
Paleschara, Hall (Twenty-sixth An. Kept. N. Y. State Mus. Nat. Hist., p. 
107. 1874). [Type, Paleschara incrustans, Hall.] 
Zoarium consisting of thin expansions, usually incrusting other bodies. Cells 
polygonal, in contact, with frequent maculrn of larger cells. 
Examples: Paleschara incrustans, pi. xvi, figs. 15-21. 
Paleschara radiata, pi. xvi, figs. 13, 14. 
*Note.— Fistulipora minor, McCoy = Calamopora incrustans, Phillips, according to Prof. H. A. Nicholson..
