Frond long, up to 20 cm, narrow, subterete, some- 
times with proliferations, variously curved, often to 
one side. This is the most common loose form met 
with repeatedly at Hofmansgave (North Fyn) and 
further in Sb, Sf and Sm. Fig. 470, 471. 
F. uncinata LyNGB. Tent. p. 16. Frond small, 
cartilaginous, linear, cylindrical, complanated only 
at the bifurcations, at the ends recurved like the 
horns of a ram. This very characteristic form has 
only been found very rarely at Hofmansgave. It is 
so different from the typical form that an anatomical 
examination is needed for the identification (fig. 472). 
F. egagropila. A much branched specimen 
forming an irregularly rounded clump was found 
lying loose on the muddy bottom in shallow 
sheltered water at Frederikshavn in company with 
f. densa. The base was not visible, it was hidden in 
the interior of the clump the surface of which 
consisted on all sides of the irregularly outward 
Fig. 471.

In the North Sea and Skagerak Chondrus crispus thrives only near land from 
a little over low-water mark to 2 metres’ depth and only where the coast is stony,

and the same can be said of its occurrence in the 
Limfjord. In the other waters within Skagen it oc- 
curs most frequently in similar localities (f. fypica 
and abbreviata), but it also grows at greater depths 
among other Algæ on stones, down to 15 m, more 
rarely to 20 metres’ depth. The boundary for its en- 
trance into the Baltic is at Kriegers Flak and Salt- 
holm, but in the most southerly part of its area it 
has only been met with at greater depths. At a 
higher level, near low-water mark, the southern 
boundary is more northerly, undoubtedly owing to 
the lower salinity of the surface water. In the Little 
Belt the southernmost locality known is at Sonder- 
balle Hoved, at 2 metres’ depth, but the specimens 
were very small, only 1—1,5 cm high. In the Great 
Belt it has not been met with near low-water mark 
south of Nyborg harbour, and in the Sound it has not been met with at this level 
south of Helsingborg. 
Chondrus crispus always grows on stones. Once only have I met with a small 
specimen growing on the stipe of Laminaria hyperborea in the Skagerak. It is often
