ad infimum refluxus limitem littoris Fseroensis, ut ad Quivig, Hoy- 
vig &c., rupibus tenaciter adli9erescens«. In his herbarium in Copen¬ 
hagen are several specimens from the above-mentioned localities 
gathered respectively on the 27th of August and the 12th of September. 
D. Cyanophyceae. 
Order CHROOCOCCACEAE. 
CHLOROGLOEA Wille. 
203. Ch. tuberculosa (Hansg.) Wille. N. Wille: Algologische 
Notizen I—VI in Nyt Magazin for Naturvidenskab. Bind 38. Kri- 
stiania 1900. 
Agreed well with Wilie’s description and figure (1. c. p. 2). 
Found epiphytic on Gigartina mamillosa growing between tide-marks 
on exposed coast. It occurred on the latter algae in crusts of a 
dark, dingy green colour. 
Found hitherto only on Str.: Hojvig Flesen (!). 
Order CHAMAESIPHONACEAE. 
DERMOCARPA Crouan. 
204. D. Farlowii nov. spec. 
A Dermocarpa which occurred on Polysiphonia fastigiata had a 
strong resemblance to D. prasina Born, et Thur. (Notes algologi- 
ques, Fasc. 2, p. 73, tab. 26, figs. 6—9) both in its 
mode of growth and in its outward appearance, 
but ou closer examination it differred so far 
from the latter species that I suspected it to 
be distinct from it. I therefore wrote to Dr. 
Bornet regarding this specimen, and he kindly Fi s- 108 - Dermocarpa Fariowu 
informed me that some years ago Professor 
Far low had sent him a Dermocarpa from Japan which appeared 
to be identical with the Fseroese specimen, and he very kindly 
forwarded me a preparation of the Japan plant, which also ap¬ 
peared to me to agree exactly with mine. Dr. Bornet also told me 
that he had written to Prof. Farlow on the subject, and Farlow 
had answered that he had not described the plant. Before I give 
a description of it I may add that I have done myself the pleasure 
of naming it D. Farlowii in honour of its first observer.
