NORTH AMERICAN EARLY TERTIARY BRYOZOA.

It differs from Puellina bispinosa in that the ordinary zooecia are deprived 
of avicularia and in the much smaller ovicell. 
Occurrence. — Vicksburgian (Marianna limestone) : One mile north of Monroe- 
ville, Alabama (rare) ; near Claiborne, Monroe County, Alabama (rare) ; west 
bank of Conecuh River, Escambia County, Alabama. 
Jacksonian (Zeuglodon zone) : Cocoa Post Office, Choctaw County, Alabama. 
Cotypes. — Cat. Nos. 64027, 64259, U.S.N.M. 
PUELLINA INARMATA, new species. 
Plate 84, fig. 15. 
Description. — The zoarium incrusts Orbitoides and bryozoa. The zooecia are 
distinct, separated by a furrow, elongated, elliptical; the frontal is only slightly 
convex; the costules are fine, radial, separated by very small lacunae, and orna- 
mented with a double row of very fine granules; there are nine or ten pairs; in 
the shield there is a very visible lumen pore. The aperture is semilunar, trans- 
verse, larger on the ovicelled zooecia, surrounded by a smooth peristome. The 
ovicell is imbedded in the distal zooecium, improminent, always closed by the 
operculum; very rarely there is a small, simple avicularium in the zooecial junction 
angles.

Affinities. — The total absence of avicularia characterizes this species. How- 
ever, sometimes on the peristome a very small pore is visible and again, in some 
of the zooecial junction angles there is a small, round, and simple avicularium. 
The double row of small granides which ornament the costules also characterize 
this species; however, this character is inconstant and many of the zooecia have 
some costules sculptured as in Puellina calamorpha Reuss. This last species lias 
two very constant, oral avicularia. 
Occurrence. — Vicksburgian (Marianna limestone) : Murder Creek, east of 
Castlebury, Conecuh County, Alabama (rare) ; west bank of Conecuh River, 
Escambia County, Alabama (rare).

In the interval which separates the zooecia there may be noted very small 
• accessory cellules hardly a fourth the size of the others but of the same form. 
These smaller zooecia are always primoserial; there are always two or three of 
them following a preceding normal zooecium. 
Genotype. — Distansescharella (C ellepora) familiaris Hagenow, 1839. 
Range. — Senonian- Jacksonian.
