 plo longioribus, extremitatibus non replicatis; chromatophoris 3 (?), 

 magnis cum marginibus serratis et pyreuoidibus maguis. In stagnis 

 ad latera rivulorum ; Febr. 1857. No. 206. 



8. Spirogyra sp. Cellulfe vegetativfe diametro (67-78 /a) 3-4^ 

 (usque 7)-plo longioribus, extremitatibus non replicatis; chromato- 

 phoris 3, cum marginibus subglabris et pyrenoidibus parvis spar- 

 sisque, anfractibus 2-3 (vel pluribus). 



Loanda. "In Angolje stagnis agri Loandensis" ; Febr. 1854. 

 No. 125. 



9. S. cylindrospora, sp. n, S. cellulis vegetativis diametro 

 l-|-4-plo longioribus, extremitatibus non replicatis ; chromato- 

 phoris 4, angustis, laxissimis, cum marginibus subglabris, an- 

 fractibus 1-3 ; conjagatione scalariformi et laterali, cellulis 

 fructiferis non inflatis ; zygosporis breviter cylindricis, polls 

 rotundatis, lateribus cellularum fructiferarum zygosporas arctis- 

 sime taugentibus, tarn longis quam latis (s^epius longioribus) ; 

 membrana zygosporte matur^a crassa, lutea, lamina mediana 

 crassissima, scrobiculata-punctata. Crass, cell, veget. 70-77 /a ; 

 long, zygosp. 78-98 /x, lat. 70-77 i^; crass, membr. 6-6-5 /x.

The shortly cylindrical zygospores are very characteristic, 

 fitting the cells like plugs pushed into them. 



10. Spirogyra sp. Cellulae vegetativte, diametro (115-126 /^)

 multis, anfractibus arctis.

ON SOME SCOTTISH RUBI. 

 By the Rev. W. Moyle Rogers, F.L.S. 



A FIRST visit to Scotland last summer gave me a long- desired 

 opportunity of studying some of the living Rubi north of the Tweed. 

 Numerous bundles of specimens received in the course of the last 

 few years had shown me that the forms most commonly met with 

 in Scotland are practically identical with those tbat prevail in the 

 South of England; but I was hardly prepared to find how general 

 the similarity really is. 



Day after day, for a month, nenrbj all the brambles that I saw, 

 as I moved about in five counties, were literally indistinguishable 

 from those one commonly meets with in the south. A few were 

 unfamiliar ; glandular foi'ms were exceptionally scarce ; and it was
