23. N. anstralica A. S. (1874). — V. elliptical. L. 0,o45; B. 0,022 mm. Lateral areas 

 linear, with slightly concave exterior margins, tapering towards the ends, abbreviate. Strise 11 

 in 0,01 mm. Puncta? — Atl. II f. 37. f. 12? 



Marine: S:t Vincent (Austr.). 



This species, unknown to the author, appears to be a small variety of N. spectabilis or a 

 form of N. Lyra var. atlantica. 



24. N, genifera A. S. (1874). — V. lanceolate. L. 0,i3 to 0,i6; B. 0,o5 to 0,o6 mm. La- 

 teral areas narrow, constricted in the middle, slightly convergent. Marginal striae 9 and their 

 puncta 9 in 0,oi mm., the latter forming longitudinal rows. Axial striae 9 in 0,oi mm. composed 

 of about 3 puncta. Puncta of the striae are confluent close to the sinuses of the areas. ~ Atl. II f. 6. 



Marine: Colon (Deby Coll.)! Puerto Caballo (Atl.). 



25. N. abrupta Greg. (1857). — V. elliptical. L. 0,0.55 to 0,o85; B. 0,022 to 0,o34 mm. 

 Axial areas distinct, narrowed towards the central nodule and the ends. Lateral areas narrow, 

 short, constricted in the middle and with convergent interior margins. Striae 10 in 0,oi mm., 

 finely punctate; puncta about 23 in 0,oi mm. or indistinct. — N. Lyra var. abrupta Greg. D. of

Marine: Spitsbergen! Finmark! North Sea! Mediterranean Sea! Adriatic! Black Sea! Red 

 Sea! Labuan! China! Fossil: Hungary (Pant.). 



N. abrupta seems to be a distinct species, not closely connected with the others, distinguished 

 by its axial area and the fine punctation of the striae. 



26. N. clavata Greg. (1858). — V. elliptical, with rostrate ends. L. 0,o4 to O.09; B. 0,022 

 to 0,05 5 mm. Lateral areas usually broad and semilanceolate with divergent ends. Marginal 

 striae 10 to 14, axial striae 14 to 16, puncta 16 to 20 in 0,oi mm. — T. M. S. IV p. 46 PL V f. 17.
