and the papers of B ii t s c h 1 i, Marion and V i 1 1 o t are well-known.

In the very last time have appeared the results of several investig-

ations of more special nature; 1 shall mention here the paper of

Jagerskiold from 1901 partly dealing with some interesting

marine forms, that of Tiirk from 1903 dealing with different spec-

ies of the genus Thoracostoma and finally those of Stewart and

Rauther from respectively 1906 and 1907, both of them dealing

with marine forms. All these investigations have brought about a

great increase of our knowledge concerning the group under con-

sideration. Finally a few faunistic papers have appeared of late,

namely the work of Southern 1914, dealing with Irish Nemat-

helmia, Kinorhyncha and Chaetognatha and in 1916 a paper of

S tein er, dealing with Nematodes from the Barentsea, published

in Zool. Jahrbiicher, Bd. 29. The same year Filipjev published

a paper entitled: „Les nematodes libres contenus dans les coUec-

tion du Musée Zoologique de l'Académie Imperiale des sciences

de Petrograd".

Danish marine freeliving Nematodes have not hitherto been

subject to investigations. In his paper (1904) on Hypodontolaimus

inæqualis Jagerskiold mentions besides this species some

others which were collected by Wesenberg-Lund at the West

coast of Jutland, namely Tripyloides viilgaris and Oncholaimus

fusens, and these are the first Danish species which have been

identified. In my paper from 1911, „Danish freeliving Nematodes"

moreover a few marine forms were recorded, namely: Monohystera

socialis Biitschli, Oncholaimus uiridis Bastian, Oncholaimus oxyuris

Ditlevsen, Enoplus communis Bastian and Rhabditis ma-

rina Bastian. All the species described in this paper, except those

named above, are new to the Danish Fauna. .
