M\\\ DIATOMS OF THE ALBATROSS VOYAGES. 349 



As Ralfe a points out, thisistoo wide of \ smithii to make pro- 



posed. I 'I" ii"i think 11 necessary to include here \ i ulata Schmidl basis done 

 by Cleve. Schmidt himself points out that they are related, but they seem ton 

 to him, worthy of 3eparat ii m.

 \lv Bpecimen agrees with the two figures of Schmidt, c N. notabilis ex pleta, which 

 make so divergent a variety thai ii would almosl I"- allowable to raise the form to spe- 

 cific rank instead of considering it a variety of the above Bpi

 It is a question if this can be maintained as a separate species from N. praetexta 

 Ehrenb. Ii is so close to N. • Truan & Witt,<*that the only point of contrast 



is in the latter having the marginal Btriae interrupted at the terminations of the raphe, 

 while ill*- above has the striae unbroken around the entire valve The close resem- 

 blance is noted by Grunow in the above citation. Cleve unite- X. haytiana with N. 

 praetexta, yel gives this separate tank. I run only say in conforming to this rather 

 inconsistent arrangemenl that the line has to 1"- drawn somewhere. It issignificant 

 that the following dredging which furnishes this form also furnishes the normal N. 

 praeU tta and the typical N. haytiana, as will be noted under N. praett

 Leaving out the unimportant matter of size, this species differs from .Y. longa 

 Greg, chiefly in it- tapering and transversely cul striae. 1 see do reason to consider 

 any of the above forms of Pantocsek as differenl from this species. Cleve unites the 

 first two here, but assigns inconsequent reasons forgiving .V. pinnata separate stand- 

 ing. Scoliopleura szakalensis is merely a contorted specimen of A", hinh i; both 

 come from the same fossil deposit at Szakal. .V. pinnata, though not recorded by 

 Pantocsek from Szakal. is of wide distribution, occurring with N. binkeri and S. 

 szakalensis at Nagy-Kurtos, as well as at Bory and Uremia. The onion of A", pinnata 

 here happens to have the added advantage of making synonymous a name too easily 

 confused with that given by Schmidt.
