I. CELLEPOEA, Fahr., 1780, (sec p. 6.) 
1. Cellepora prona, StoUczka, PL I, Eig. 1. 
Cell, colonia cellnlis nrceolatis, parvis, decumhentUms, parte anteriori elevatis et 
contractis composita, cellnlis in snperficie lota porosis, siilcis angustis, hand pre- 
cipne distinct is, et in coloniis anliqnis snh-ohsoletis separatis. Apertnra parva, 
snhrotnndata, fere horizontali, marginibus valde incrassatis circumdata, poris avicu- 
lariorum tribus subverrucosis instruclis, iino in utroque latere tertioque medio labii 
sito. Ovicellulis rare conspicuis, parrulis, rotundatis, paulo elevatis, ad basin cum 
labro apcrturce fere confluentibus, snperficie Icevigatis. 
The cells of this species are very small, with the anterior part contractccl, 
elevated and thickened, while the posterior is almost horizontally reposed, in 
younger colonies somewhat convex and separated from each other hy slight impres- 
sions, which in old colonies become nearly obsolete. The entire surface is rather 
coarsely porous or almost scrohiculate. The aperture is nearly in a plane, small, 
sub-rotundate, with very thickened lips and three verrucose avicularian pores, one 
on either side, and the third situated about the middle of the nnderlip. The ovicells 
appear to be rarely developed ; they are rounded, small, smooth, and at the base 
nearly confluent with the upper lip. When the surface of the ovicells has been 
broken in, the thickened upper lijD becomes better marked and shows a large poi'e 
above it in the jflace of the ovicell. 
Locality. — North of Poodoopolliam, incrustiug Terebratula subdepressa, StoL, 
occurring in a pinkish-yellow sandy limestone. 
Formation . — Arrialoor grouji. 
2. Cellepora puxcticulata, StoUczka, PI. I, Eig. 2. 
Cell, colonia cellulis sub-cylindraceis, decumbentibus, Icevigatis, punctis incequalibus 
plus minusve distinctis separatis ; apertura terminali, antica, transverse subrotundata, 
margine obtuso paulum incrassato circumdata, declivi, labro fere immerso, labio 
convexiusGulo et elevato ; ovicellulis supra aperhiram positis, eamque in magnitudine 
fere eequantibus, paulo convexis, solidulis, nonnunquam fissurd parva supra labrum 
aperturce sita instructis. Fissoribus forma cellulis ceteris similibus, scepissime 
aliquanto minor ib us. 
A very characteristic species, the cells being, like in the previous one, decumbent, 
but separated from each other by irregularly punctated, or rather scrohiculate, 
impressions. The form of the cells is subcylindrical, moderately convex, with the 
aperture anterior, terminal, transversely subrotundate, slanting, the upjjer lip being 
nearly immersed, while the lower lip is considerably elevated, and in most specimens 
the cell below it is slightly constricted. The ovicells are placed above the aperture,
