Vertebralina, striata d’Orb., 1826, Ann. Sci. Nat., vob vii. p. 283,

The majority of the Malay specimens have the peripheral margin 
angular or carinate, as in V. insignis Brady, but in all the test is 
inequilateral, and one lip of the aperture protrudes beyond the other. 
Thus, although most of the specimens combine certain of the characters 
of the two species, the typical V. insignis is not represented. As will 
be seen from the figure, which is drawn as viewed by transmitted 
light, the test commences with a planospiral chamber. 
It occurs at several Stations, but the specimens are small and 
feeble.
