particularly to the material in question being very scanty. In his 
Hydrophytologia Lyngbye also gives accurate and valuable infor¬ 
mation regarding the habitat and distribution along the Faeroese 
coasts of almost all the species found by him. 
Besides the large number of Faeroese algae which are enume¬ 
rated in Hornemann’s »Plantelaere« 1 on the authority ofLyngbye’s 
work, a few are added to the list, viz. Polyides liimbricalis - P. ro- 
tandus and Callithamnion corymbosum of which I shall give a 
fuller account later on. Trevelyan’s 2 paper must also be men¬ 
tioned, though the Faeroese algae reported in it are likewise only 
an extract from Lyngbye’s Hydrophytologia. 
The next independant work which has increased our knowledge 
of the Faeroese algae is »Faer 0 ernes Flora« published in 1870 by 
E. Rostrup 3 , in which he gives the results of a journey made in 
1867 to the Faeroes in company with C. A. Feilberg. In this work 
ten new species of marine algae are added to the flora, among which, 
however, as I have explained more fully later on, there is some 
doubt as to whether the species Chcetopteris plumosa which Rostrup 
received from a Mr. Randropp of Thorshavn is really from the 
Faeroes. The total number of species of marine algae reported by 
Rostrup is not far from 100. The determinations of the material 
in question were revised by Professor J. G. Agardh of Lund and 
Professor J. E. A reschoug of Upsala. 
The latest contribution to the marine algae of the Faeroes we 
owe to Herman G. Simmons who visited several parts of the 
Faeroes in the same year as I had begun my investigations, viz. 
in 1895, but somewhat later than I. In his work »Zur Kenntnis 
der Meeresalgen Flora der Faeroer« 4 125 Faeroese species are men¬ 
tioned, as his list also includes the 16 species (of which 2 are 
classified as genera only, and 1, Porphyra miniata, had been already 
recorded by J. Agardh as Faeroese) which I published in my preli¬ 
minary list of 1896 5 , together with the Laminaria lingicruris var .
