The American fossil specimens have not the delicacy of the recent species, the 

 segments being generally a little larger. The same is true of the examples found 

 in the Lutetian of France. The measurements are quite variable on the same 

 segment. We consider the upper zooecia of a segment as the more normal ; the 

 measurements for these arenas follows: 



. \ho=O.BO mm. . (Zz=0.40-0.50 mm.

Below the opesium there is sometimes a small isolated radicular pore. The 

 lower zooecium is often incomplete and bears only a radicular pore. The ovicells 

 are very difficult to distinguish. 



Occurrence. Vicksburgian (Marianna limestone) : Salt Mountain, 5 miles 

 south of Jackson, Alabama (abundant) ; Vicksburg, Mississippi (rare in the lower 

 beds). 



Vicksburgian (Byram marl) : West of Woodward, Wayne County, Mississippi 

 (rare) ; Byram, Mississippi (rare). 



Geological distribution. Lutetian of the Paris Basin (Canu) ; Helvetian of 

 Egypt (Canu) ; Miocene of Australia (MacGillivray). 



Habitat. Pacific: Australia, Crozet Island and the Philippines. Indian 

 Ocean : Off Ceylon, Mergui Archipelago, Zanzibar, and in the Red Sea. Atlantic : 

 Off Florida, St. Thomas, and the Tortugas. 



Specimens have been dredged from a depth of 17 to 450 meters. Off the 

 Tortugas Islands Osburn mentions that it is abundant on sponges from 20 to 28 

 meters. The Tertiary Gulf was certainly deeper than to-day and for this reason 

 fossil examples are rare.
