Distribution in General: 
Arctic and Northern Seas. NSamples of this species were also found by SARS 
at Skraaven in Lofoten (KOREN and DANIELSSEN). 
To judge from the two original specimens at my disposal, presented to the 
State Museum by M. SARS under the name of Ph. levissimum, and from the dia- 
gnoses and figures of KOREN and DANIELSSEN (not from their deseription, which very 
likely concerns the former form), there may exist some differences between Phascolosoma 
anceps and that form which they have called Ph. Sarsii, and which they assert to 
be identical with the Ph. levissimum of M. SArRs (Cp. the description of the two 
Norwegian investigators with their diagnosis and figures!). Having had the oppor- 
tunity of examining the type of Ph. Sarsi, dredged up by G. O. SARS at Skraaven, 
and named Ph. levissimum by his father M. SARS, and of comparing it with the 
specimens from the Christiania Fjord, which also bears the name Ph. levissimum of 
M. SaArRs, I venture to assert that it seems very probable that he too has con- 
founded them. 
The two defective specimens at my disposal do not allow me to enter into a 
closer examination. The proboscis is 15 mm. long and the trunk itself 12 mm., 
consequently the total length amounts to 27 mm. As far as I can see, the dubious 
species in question resembles in most respects Ph. Sarsii, and differs from it mainly 
in its greater size, in the proportions between the length of the proboscis and the 
trunk, and in the fact that the proboscis in an extended condition presents an in- 
flation anteriorly. The differences may seem inconsiderable, and further investigations 
may give us light as to whether Phascolosoma anceps represents a distinct species, 
or is identical with one of the former species. 
The description below concerns those small forms which were brought home in 
great numbers by several Swedish Expeditions to the Arctic Sea.
