PUELLINA RADIATA ANATICULA, new variety. 



Plate 41, fig. 19. 



This variety is characterized by the little canal of the avicularium. which 

 is enlarged like the beak of a duck. All the other characters are identical with 

 the type form. 



Occurrence. Middle Jacksonian : Seventeen miles northeast of Hawkinsville, 

 Georgia (very rare). 



Upper Jacksonian (Ocala limestone) : Seven miles above Bainbridge, Georgia 

 (very rare) ; Bainbridge. Georgia (very rare) ; 4 miles below Bainbridge, Georgia 

 (very rare). 



Vicksburgian (Byram marl) : Byram, Mississippi (rather rare).

 1'olyzoa of North America, Journal Academy Natural Science, Philadelphia, vol. 5, 

 p. 136, pi. 19, fig. IS. 



This variety is characterized by its smooth peristome, without tuberosities, 

 nnd by the small distal canal of the avicularium, which is larger than in the type. 



In reality the spines have not disappeared; on the perfect specimens they are 

 still visible ; but they never have the size and the importance of those which decorate 

 the type. The zooecia are a little larger and have 16 costules. 



Occurrence. Middle Jacksonian: Near Lenuds Ferry, South Carolina (rare). 



Upper Jacksonian (Ocala limestone) : West bank of Sepulga River, Escambia 

 County, Alabama (rare). 



Vicksburgian (Marianna limestone) : One mile north of Monroeville, Alabama 

 (rare). 



Vicksburgian (Red Bluff clay) : Seven and one-half miles southwest of Bladen 

 Springs, Alabama (rare).

PUELLINA BISPINOSA, new species. 



Plate 41, fig. 22. 



Description. The zoarium incrusts shells (chiefly Ostrea vicksbwrgensis) and 

 other bryozoa. The zooecia are elongated, distinct, separated by a furrow, ellip- 

 tical; the frontal is convex and formed of from 16 to 18 thin costules separated 

 by very small lacunae and traversed by a line of lumen pores. The aperture is 

 formed of a semilunar anterior and of a very convex posterior portion separated 

 by two very small cardelles: the posterior portion is hidden by a small, prominent 

 mucro. The ovicell is globular, salient, always closed by the operculum. On each 

 side of the aperture there are two small triangular avicularia pointed, longitudinal, 

 between which occur two large spines.
