the above species are mostly characteristic of mesozoic strata ; 

 but the species has also been recorded from recent soundings off 

 Moncoeur Island, Bass Strait, at a depth of 38 fathoms. 



Our specimen somewhat resembles a closely allied form which 

 was found in the gault of France and England, Vaginulina 

 biochei, Berthelin.' The latter form, however, is distinguished 

 by the thickened sutures of the chambers having a tendency to 

 become salient, especially on the inner (anti-stoloniferous) margin 

 of the test. 



Occurrence. — One specimen (small) ; Jurassic, Greenough River 

 district, W. Australia. [2127].

Remarks. — The striate Vaginulinae are of very frequent 

 occurrence in mesozoic strata, and are fairly common throughout 

 the whole of the Jurassic and cretaceous strata. 



The particular form under notice is distinguished from others 

 closely allied by the more pronounced striations on the surface 

 of the shell, and which bridge over the sutui'e lines, the latter 

 being more or less depressed. 



Occurrence. — One specimen (fragmentary); jui-assic, Greenough 

 River district, West Australia. [21 28. J
