 There are various forms, varieties, or species of Amphistegina
 ,in the American Tertiary which should be critically studied as from the fragmentary evidence at hand they seem very distinct at different horizons.
 As Amphistegina is a tropical genus the occurrence in the wells
 would naturally be expected to be confined to those of the southern e part of Florida. This is true of the actual records, it having occurred as follows: City Well at Fort Myers at 300 feet; well of the Okeechobee Ice and' Electric Company at Okeechobee at 56-62 feet; and in the well of the Florida East Coast Railway at Marathon on Key Vaca, at I8o feet.
 It is know from the Miocene of the Duplin Marl of South Carolina, the Choctawhatchee Marl of Florida, and the Miocene of Santo Domingo and Bowden, Jamaica,. and in the upper Oligocene of the Panama Canal Zone.

 Genus Asterigerina d'Orbigny, 1839.
 Asterigerina angulata Cushiman.
 Asterigerina angulata Cushman, Publ. 291, Carnegie Institution of Washington, 1919, p. 45. pl. 13, fig. I.
 Numerous specimens from a depth of 786 feet in the well at
 Marathon. Key Vaca, are evidently this species, described from the Miocene of Santo Domingo at Rio Cana, and Cercado de Mao.

 Genus Numnuulites Lanarck. i8oi.
 Nunnmulites sp.
 Numerous specimens of ANtimmnlites occur in a number of the
 wells, usually just below the Ocala limestone where that formation is represented. The records in the various Florida wells are as follows: a fragment probably NAimmilites from 400-470 feet in
