Localities. — Station 3383, at the base of the bluff at Little Horse- 

 shoe bend, on the east bank of the Flint Eiver, just below the mouth 

 of Blue (or Kussell) Spring branch, four miles below Bainbridge, 

 Decatur County, Georgia, in fossil coral reef; T. W. Vaughan, 1900. 

 U. S. Nat. Mus. Cat. No. 166787. Also from the OUgocene limestone 

 at Wliite Beach, Florida, and the Orthaulax yugnax zone at Ballast 

 Point, Tampa Bay, Florida; Dall and Willcox. U. S. Nat. Mus. 

 Cat. No. 165099. 



Imperfect but perfectly identifiable fragments were obtained by 

 Doctor Vaughan. 



In response to a criticism by M. Cossmann mat a perfect specimen 

 was not figured in a recent publication, it may be noted that a perfect 

 or nearly perfect adult specimen of tliis species is yet unknown. All 

 that collectors have been able to secure so far are either immature 

 specimens or fragments. Out of several hundred specimens of 0. 

 gain obtained at Alum Bluff only one retained the outer lip, and a 

 complete specimen of 0. pugnax is stiU a desideratum.

Localities. —StsitioB. 7074, on the west bank of Flint River, 7 miles 

 southeast of Bainbridge, Decatur County, Georgia, at Hale landing, 

 in coralliferous chert; and station 7079, on the east bank of Flint 

 River below the mouth of Blue (or Russell) Spring branch, at Mascot 

 Point, in chert blocks; Vaughan, Cooke, and Mansfield, 1914. U. S. 

 Nat. Mus. Cat. No. 166788. Also from the Oligocene zone of which 

 it is the type fossil, at Ballast Point, Tampa Bay, Florida; from 

 Antigua, Cuba, and the Panama Canal Zone. 



This can be distinguished at once from 0. inornatus by its stouter 

 and shorter form and blunt spire. Of neither species has an abso- 

 lutely perfect specimen been collected, the thin expanded outer lip 

 being invariably defective.
