From the Botanical Gardens I have further had some old her- 

 hariuin material from the Færoes for exainination; 24 gather i rigs 

 in all, of which 3 were eollected by E. Rostrup, and of the olher 

 gatherings the greater part was from Lyngbye's Herbarium. Of these 

 24 gatherings, 7 were freshwater gatherings and contained Diatoma 

 hiemale Lyngb. (5 gatherings), and Gomphonema geninatum Lyngb. 

 (2 gatherings); the remaining 17 gatherings, on only a few of which 

 the habitats were mentioned, contained: —

The material which I had for examination needs only a few 

 short remarks. Il was kindly selecled for mc by Mr. Borgesen, 

 partly from his own considerable material of Fæ roe se marine 

 algæ and partly from Mr. Helgi Jonsson's gatherings. On making 

 the selection Mr. Borge sen had two objecls in view. First, to 

 choose such algæ as were rich in Diatoms, and secondly, to provide 

 me with gatherings from many different localities, so that a fa hiv 

 satisfactory result could be arrived at with regard to the Diatom- 

 Flora belonging to the Færoe se marine algæ. With regard 

 lo the laller object, a comparison between the map of the Færoes 

 and the localities menlioned in the following list will show how 

 carefully the work has been done, and I must express my hest 

 thanks lo Mr. Borgesen for his kindness in obliging me on 

 this point. 



I have received gatherings from the following localities: —
