 Geol. Survey, 1918, p. 61, pi. 18, fig. 3. 



A single specimen from the Ponce de Leon Well at St. Au- 

 gustine is the only record for the species in the well samples. I 

 have also had it from the Miocene in the Choctawhatchee Marl 

 from Goes Mill, Florida.

This species seems to be a common one in the Miocene and 

 Oligocene of America. It was originally described from the Mio- 

 cene of the Choctawhatchee Marl at Goes Mill, Florida, from the 

 Duplin Marl at Mayesville, S. G., and from Wilmington, N. G- 

 It is also known from the upper part of the Gulebra formation 

 of the Panama Ganal Zone. 



In the borings from the Florida wells it has occurred as fol- 

 lows : Ponce de Leon Well, St. Augustine, at depths of 88 and 200 

 feet ; well at Fort Myers, 300 feet ; well of Okeechobee Ice and 

 Electric Gompany, Okeechobee, Florida, 41-56 feet; 87-94 feet; 

 240-245 feet ; 245-276 feet and 403-458 feet ; well at Maratjjon on 

 Key Vaca, 180, 305 and 398 feet.

 187s, p. 78, pi. 10, fig. 8. Cushman, Bull. 103, U. S. Nat. Mus., 1918, p. 68,

Truncatulina pygmaea H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 

 9, 1884, p. 666, pi. 95, figs. 9, 10. 



Specimens occurred in the material from two wells, that from 

 Fort Myers, at a depth of 360 feet, and from the well at Marathon 

 on Key Vaca, at 398 feet.. 



It has been recorded from the Miocene of the Gatun formation 

 and the Oligocene of the Gulebra formation of the Panama Ganal 

 Zone. •
