FORAMINIFERA OF THE CARBONIFEROUS FORMATION. 365 
Asia and Arabia, Dr. Bailey has transmitted me specimens 
| of limestones containing foraminifera, chiefly of the genera 
- Rotalia and Textularia.* 
' 
. In the calcareous marls of the Upper Missouri river, 
_ extending nearly to the Rocky Mountains, similar fossils are 
met with. 
In the interior of Florida, the white orbitoidal limestone 
_ is traversed by flint ; and the calcareous and siliceous masses 
are full of microscopic foraminifera.t 
FORAMINIFERA OF THE CARBONIFEROUS Formations.—In 
_ the carboniferous limestones of England, the late Mr. Bow- 
man, Prof. Tennant, and Mr. Darker, detected shells of 
foraminifera, apparently of the genus Fuswlina.t Prof. 
_ Phillips mentions the occurrence of nautiloid foraminifera in 
the palzeozoic limestones of Carrington Park, South Devon, 
and Yorkshire.§ 
Dr. Dale Owen is said to have obtained “well characterized 
_ polythalamia from the oolitic portion of the carboniferous 
 (Pentremitic, ante, p. 298,) limestone of Indiana.”|| And 
M. de Verneuil discovered a species of Fusulina, in the Mill- 
stone grit of the coal formation of the Ohio. 
But the most remarkable deposits of foraminifera in the 
palzeozoic rocks, are those of Russia, described by Sir Rode- 
_ rick Murchison. The upper beds of the Mountain limestone 
in the Lower Volga, consist of laminated calcareous shales, 
- composed of an aggregation of shells of Fusuline. Bands of 
limestone, through a vertical extent of two hundred feet, are 
loaded with Fusulinz ; layers from five inches to five feet
