The pedunele shows two distinet parts; the upper one is slender 
while the under one is thickened forming a short eylinder. Mus- 
cular fibres only present in the basal portion of the peduncle. Stem 
of the colony articulated. Rare. 
Locality: Barents-Sea. 72° 5’ N. lat., 37° 57’ E. long, 140 fathoms. 
Habitat: On Menipea ternata. | 
Family LOXOSOMIDAE. 
Genus: Loxosoma, Keferstein. 
27. Loxosoma Nitschei, nov. spec. (fig. 4, 5). 
On a little specimen of Menipea ternata I found a small number 
of interesting solitary organisms, which at first sight appeared to 
be representatives of the Genus Loxosoma. 
This interpretation is founded only on the habit and the external 
characters of the body; unfortunately the animals were so badly 
preserved, that it was impossible to study at all thoroughly the 
anatomical and histological structure. There are eight conical ten- 
tacles forming a crown, surrounding a central opening, probably 
communicating with the intratentacular space. In some specimens 
I found on the polypide one or two lateral buds of different size. 
According to the number of the tentacles this form corresponds 
with the Loxosoma cochlear which was first observed by Oscar Schmidt 
at Naples, and afterward briefly described by him. (Archiv f. mi- 
krosk. Anatomie. 12). 
However on comparing the habit of the body of both these forms, 
there is, I believe, a great difference between them. The body of 
the Arctic form is not slender („schmal’”’ Osc. Schmidt) as in Loxo- 
soma cochlear, but distinctly short and compact. 
The polypide is broad, shield-like and distinetly separated from 
the short peduncle. 
All the specimens exhibit the same morphological characters. 
Since, so far as I know, literature contains no account of still 
other Loxosoma-species with eight tentacles, I am inclined to regard 
the present form provisionally as a new species, hoping to complete 
and to verify afterward these preliminary observations.
