 18 in 0,01 mm., crossed near the margin by a line. — Pl. V f. 24, 25.

The var. intermedia is a form connecting N. fallax with i\. definita. 



17. N. fallax Cl. N. Sp. — V. elliptic-lanceolate, with rounded ends. L. OjOg."); B. 0,032 

 mm. Median line with the terminal fissures in contrary direction. Area very broad, lanceolate. 

 Striee 20 in 0,oi mm., radiate thronghout, punctate; puncta about 23 in 0,oi mm. The striee 

 seem to be crossed near the margin by a fine line. — Pl. V f. 27.

This interesting species seems at the first view to be Nav. nclndo.sa, ha\ing the ontline and 

 marginal striate band of the latter, but a closer inspection shews that it is entirely different, 

 having no rows of stritt' along the median line. In fact it is nearly akin to N. definita.

As Grunow has already remarked there is no specific distinction between N. placita and 

 N. Hochstetteri. Nearly akin to N. Hochstetteri is N. Beta, which differs only by its less coarsely 

 punctate strise. 



19. N. Beta Cl. N. Sp. — V. elliptical, with broad rounded eiid.s. L. 0,043; B. 0,o25 mm. 

 Median line with the terminal fissures in the same direction. Area broad, lanceolate. Strite 13 

 (middle) to 17 (ends) in 0,oi mm. radiate at the ends, in the middle alternately longer and shorter, 

 finely punctate; puncta about 26 in 0, 01 mm. — Pl. V f. 30.

Unknown to the author. It has a considerable likeness to N. mutica var. undulata.
