 Both ni iliese 1 considi^r distinct, ns do De Toiii an<l others. Schmidt gives his name 

 mhda, though expressing donht of its not being a vaii( ty of .S. robusta. Despite 

 his very assertive^ spe( iflc nainc, I think the doubt is well founded. It is the varit^ty 

 most common in the following dredging.

My specimen agrees perfectly with the figures by Schmidt, named by Eulenstein 

 '* C. rrrbrfrostaf}i.9 Grev." This identification is false, as can be seen by comparing 

 with Greville's original figure and description.'^ (Jreville recognizes the probability 

 of this species being identical with Tohnston's C. vianjhmtns, and lie so names it in 

 bis illustration. The i<lentity is a fact, but Jolinston's Jiame is inadmissible, having 

 been preempted l>y ]']hrenberg^ for a quite different species, I am not satisfied 

 with making the above species synonymous with C. imperiaUa Grev., as is done by 

 De Toni.f Grevillo's figure and description show marked differences, especially in 

 the border. Put whether synonymous or not, De Toni's selection of tlie name impcr- 

 iaUs is wrong, as hiAh the above name and that of Johnston hold priority. De Toni
