present type, the marginuline species becoming vaginuline by 

 the continued compression of the test. Our specimen seems to 

 occupy a place midway between these genera, but since it agrees 

 with the original figure of Marginulina compressa given by 

 D'Orbigny, rather than with the flatter type, Vaginulina 

 legumen, Linne sp., it maybe conveniently retained in the former 

 genus. M. compressa has been previously found in the 

 neocomian pebble beds of Littleton, near Guildford, England 

 (Chapman); the greensand of Le Mans, and the chalk of Meudon, 

 France (D'Orbigny) ; the chalk of Charing, Kent, England 

 (Jones in Morris's Catalogue); and the chalk of Bohemia (Reuss). 

 Occurrence. — One specimen; Jurassic, Greenough River district, 

 West Australia. [2124.]

Remarks. — The Australian specimen evidently belongs to this 

 species, which, although variable, shows certain features which 

 enable one to place it in the group with Marginulina glabra, 

 D'Orb., for a central type ; this particular form being altogether 

 slenderer and more compressed than the species just mentioned. 



The specimens to which references are made above came from 

 the upper Jurassic beds of Poland and Switzerland. 



Comparison may also be made with the M. pauciloculata of 

 Hantken,^ from the eocene of Hungary, which is also a com- 

 pressed few-chambered form of the type of M. glabra.
