Lagena orbignyana, var. variabilis, I^ov. (Plate xx. Figs. 9, 9 b.) 
This variety is more elongate in contour than t]ie typical L. or- 
bignyana, and at times has the lower portion of the convex faces 
ornamented with short riblets, as in the specimen figured. 
Prequent at 750 fathoms. I have also met with this variety 
in several of the "Porcupine" soundings from the I^^orth 
Atlantic.
