\Villiaiii Smith in disciissiTi^ the r(4ations of this gciui.s, eoiisiih-rs il ht \)o (.Vk^v to 

 those n)bnst fonnw of Nilzseliia wliich he ealls TryliUoiiella; ilt< nearer aflinity is, 

 how(>vor, <"\inipylo(lis<-UN Eln-t^nb.^ hnm which it differs simply in I lie ein-ular outline 

 and uniform twaddle shape of the latter. These differenees are so constant that an 

 unnecessar}' loss to elassilication would result from uniting th(^ two genera. The 

 nearest approach to an intermediate form is to be found in SurireUa >ip'iraU:s Xiitz, 

 {Ca)npylodiscus .splralla {Kuly..) W. Smith «). The g<'mis has a uun'v remote resem- 

 blanee to Sphincttuystis Ihiss. (Cyinalophuia W. Smith), but except in a few forms 

 no c(uifusion can arise l)etween tlu* two. 



The separation of the grciitly elongated forms into the genus Stenopterobia of the 

 kidney-shajied sports into the genus Plagiodiscus and of the formw showing a wedge- 

 shaped appearance from the zonal side into the genus Novilla are utterly useless 

 distiiK'tions. The attemj)! of PlitzcT and De Toni to change the name into Suriraya 

 so "as to make it fit belter the name ol the Frem-h physician, Doctor Suriray, in whose 

 honor Turi>in formed the name, is inexcusable, as Turi)in had a right to call his genus 

 whatever name he wish(»d.

Kiitzing, (irillilh and ITenfrey, and Raberdiorst have rightly united iS". hifrovs and 

 S. bi^rriatti under the former name. Most authors give preference to I>rel,tisson's 

 name^ though nearly all ex(^opt Schmidt in his Atlas recognize that the two are synony- 

 mous. Ehrenberg's name, accompanied !)y a clear diagnosis, is prior to that of Breb- 

 isson. Itin found in the volume of the Abhandlungcn foi' 1833, whiidi is dateil bS35;
