mud, 800 m. (SLUITER)'. Coasts of France (BLAINVILLE, KEFERSTEIN, GRUBE, ROULE” 
ete.). Mediterranean Sea (NSELENKA, MARION, CARUS, FISCHER” etc.). Red Sea (SE- 
LENKA etc.). 
Thus, the species in question has a very extensive distribution. Up to now it 
has been taken for granted that it does not live in the Arctic Sea. Since, however, 
two small specimens have been brought home from Greenland, which, for the present, 
have been referred by me to this species, the question may be left open, as to whether 
the species has a distribution in that sea too. Along the Scandinavian Coasts it seems 
to have a distribution from the Trondhjem Fjord in the North to the Sound in 
the South. 
With regard to the two small samples from Greenland, the largest of which 
has a total length of 45 mm., the stramge locality makes one dubious about the cor- 
rectness of the identification. However, as far as I have been able to make out, the 
sample from HEast Greenland agrees with the typical forms in the arrangement and 
shape of the tentacles, in the presence of a girdle of hooks behind them (though they 
are small and of a light colour), in the posterior extremity of the trunk being rust- 
coloured, and, furthermore, in the presence of two segmental organs and four retractor- 
muscles, as well as in the general shape of the intestinal spiral. The only difference 
to be noted concerns the papillx of the skin, which are of a rather minute size. The 
sample from West Greenland agrees with the above in all respects, except that it 
lacks the rust-colour posteriorly. 
According to its age, habitat and state of contraction, the species presents itself 
under different guises. A certain diversity of colour is also discernible. Thus, a rather 
large specimen, 155 mm. long, from Gullmarn, shows a light reddish or brownish 
colour, like rust, with the proboscis and the posterior extremity of the body slightly 
darker. Another sample, of about the same size, is deeply rust-coloured and has the 
ends, especially the posterior one, which is remarkably pointed, almost black, and sharply 
marked off from the remaining part of the body. Smaller specimens from Bohuslän 
are whitish, more or less transparent, and always present traces of a reddish or 
brownish colour at their extremities. According to my opinion, the Phascolosoma 
Harveii of FORBES represents young forms of the species in question, while the robust 
and more or less deeply coloured Phascolosoma papillosum of THOMPSON may be 
specimens - of comparatively great age. In the young individuals the body-wall is 
transparent and, as a rule, the trunk presents traces of the characteristic brownish 
or ferruginous colour at both extremities. Furthermore, the young forms seem to 
possess, for their age and size, rather large cylindrical papille, especially at their 
posterior extremities. 
In view of these diversities and also of the fact that I was totally in want of 
types for comparison, when I was working with the Gephyrea nearly thirty years
