 \- ( it is impossible to decide positively what N. apis (Ehrenb. Km/. 



really denotes. Ehren berg's figure and description of Pinnularia apis make it rea- 

 sonably certain that it is not the present - j »« *< i«-~ ; nor are the synonyms cited by 

 D .nkin at all illuminating. Kutzing's liumre'' is almost anything but Donkin'e 

 dial <>u i. ami more unlike it, if possible, is W. Smith's figure determined a- .V. didyma 

 Kiit/..' 1 therefore look upon Donkin's form as a distinct species. Although Ehren- 

 name can not be satisfactorily determined, it is inapplicable t<. ? 1 * « - pi 



above noted, and as there is so much doubt about < Iroveand Cleve 'a identifi- 

 cation it may be advisable to drop the name entirely until more accurate in fun nation 

 i- available. I have therefore selected the name omaruensis a- the only one tenable. 

 The i* Tin called N.apis Ehrenb., by Grove and Clev< Grove A 



1 i e unites with N. adonis Brun, to which it bears no trace of resemblance. 

 d bundles the whole li-t together under N didyma Ehrenb., giving without 

 comment many utterly irreconcilable figures./ That Schmidt recognizes the 

 independent status of Donkin's form is evidenced by the figures given by him under 

 that name. 5
