pect it is a synonym of some other form. 1 have l)een^ however, unable to find such, 



and as my spcM'iun^n agrees with Smith's type I am compelled to assign this name

Il is not p(Tfeelly clear that Greville's and Gregory's si>ecies are the same. That 

 of Greville would appear from the figures to be much more finely Ix^aded, particularly 

 ashosavs its beading is "very minute/' especially toward (he median line. The fa(^t 



is also against their identity that Grevilh> inade the drawings for Gregory's ])aper, 

 including this v<Ty form, yet does not look upon his own publication as a renaming 

 of the same diat(mi. But they ar(^ united by Clove, Grunow, De Toni, and others, 

 while Ralfs holds them separate. If admitted to l>o tln^ same, which seems on the 

 whole to be best, tin? cpiestion what name should be assigned i)resents somedilRcullies. 

 Both names w(Te ]>ubliBhed in 1857.^ There is no record in the Proceedings of the 

 Lond(m Micros(M)pical Society as to when Greville's paper was presented, in the reeorda 

 either of 185G or of 1857. Gregory's paper w\is read January 19, 1857, and appeared 

 that year. The preference would, lherefor<% be in favor of Gregory; and as his name 

 is the better estabHshed of the two, I have for all these reasons adopted it. 



Grimow's Mdosira cnbrosa must be included here. It appears to me more nearly 

 to resemble tlu^ Greville type than that of Gregory, though Grunow and (Teve take 

 an opposite view. It is also rathfM' dillicult to see the reasons for assigning only figures 

 10 a, b of Grunow's figures to this species and placing the otluT two, figures 10 e and d, 

 in different species, as Grunow does./
