walls calcareous, smooth, and polished; sutures clearly marked, but 

 not deep; aperture elongate, narrow, comma-shaped; color, white. 



Length about 0.50 mm. . 



Distribution. — This species is well distributed over the North 

 Pacific in water of medium depths, few stations being 

 less than a thousand fathoms. 



There is some confusion as to the application of 

 d'Orbigny's name, but it is here applied to the rather 

 thin, broad, tapering form with oblique chambers, such 

 as is shown by d'Orbigny's model. With such an appli- 

 cation it may be rather easily distinguished from the 

 more rotund, less tapering V. subsquamosa Egger.

Description. — Test elongate, tapering, the chambers 

 somewhat oblique, with slightly depressed sutures, slightly inflated in 



the narrower forms ; test in side view 

 somewhat curved; walls calcare- 

 ous, smooth and polished; aperture 

 elongate, fairly broad, comma- 

 shaped; color, white. 

 Length 0.40-0.65 mm. 

 Distribution. — This species has 

 been recorded by Brady, Goes, and 

 Bagg from the North Pacific; from 

 the Hyalonema- 

 ground, 345 fath- 

 oms, off Japan by 

 Brady; from the 

 eastern Pacific in 

 1,132 fathoms by 

 Goes; and from 

 about the Hawai- 

 ian Islands by Bagg, in 275-1,544 fathoms. I have found specimens 

 referable to this species from many stations well scattered over the 

 North Pacific.
