MILIOLINA PULCHELLA. 123 



Occurrence. — Miliolina hicornis is a sliallow-water form. It occurs in all 

 temperate and tropical latitudes, and is common on the British coasts. Fossil 

 specimens have been obtained from the Eocene of the Paris Basin and the London 

 Clay, from the Miocene of Vienna, and Muddy Creek (Victoria), and from the 

 Pliocene of Italy and St. Erth. In the Crag it has been found at Sutton only.

Characters. — Short, compact ; chambers rounded. As varieties of Miliolina 

 bicornis {Brongniartii), Dr. Brady (op. cit., page 173) refers to M. Boueana (d'Orb.), 

 M. Nussdorfensis (d'Orb.), M. striatella (Karrer), and M. costata (Terquem) ; and 

 states that his M. scrohiculata is probably a variety of the same species. 



So also Dr. Goes (op. cit., p. 114) combines these and others in the same 

 varietal group. 



Occurrence. — The striated adult form of Miliolina hicornis, often figured under 

 the name of M. Brongniartii, may be taken as the immediate relative of this 

 variety Boueana ; and, as such, its range is of interest. 



Recent specimens of M. Brongniartii are of rather common occurrence in the 

 shallower waters of the Mediterranean and of most tropical seas. It has also been 

 found off the coast of Galway. Fossil specimens have been recorded from the 

 Eocene of the Paris Basin, the Miocene of Vienna, of Baljik (Bulgaria), and of 

 Muddy Creek (Victoria) ; the Tertiary beds of Palermo ; and the Pliocene of 

 St. Erth. In the Coralline Crag it has been found at Sutton only.
