Genus Vagifiulina, D'Orbigny. 



Vaginulina schloenbachi, Reuss, var. interpupta, nov. 

 (PI. XXII., Fig. 5). 



This variety is distinct from the specific form V. schloenbachi^ 

 in having the long curved costae interrupted in the posterior 

 area of each chamber. The costae themselves are also more 

 numerous, averaging six in each series in the variety, against 

 three in the type form. The original species came from the 

 neocomian beds of North Germany. 



Occurrence. — One specimen of this variety was found in the 

 Jurassic of the Greenough River district, West Australia.

Remarks. — These compressed quasi cristellarian forms appear 

 more properly to belong to the genus Vaginulina, as it is now- 

 understood, since the pi-esent type of shell has no distinct spiral 

 commencement, and the test is uniformly flattened. The few- 

 chambered, broad, compressed shells which may be referred to
