I. 
Last year I occasionally obtained by the kindness of Mag. P. 
Kramp some material washed o ff from Algæ, Hydroids and stones, 
all originating from the pier of the little harbour of the Skaw. 
This material, for which I beg Mr. Kramp to receive my sin- 
cere thanks has furnished several free-living Nematodes among 
which some proved to be of special interest. 
Krampia n. g. 
I shall first deal with a genus not hitherto described, which I 
give the name of Krampia after Mag. Kramp, who was the first 
to capture it. 
Nematodes of a shape rather siender, almost filiform. The 
greater part of the body is of about equal width only slightly 
tapering towards the ends. In the formemost part it begins to 
taper at about the base of the oesophagus towards the base of the 
buccal cavity from where it tapers more quickly so that the head 
appears somewhat constricted. The head is truncate and provided 
with four lips which are rounded and somewhat swollen, and which 
seem to be movable. A ring of rather stout setæ is situated round 
the head, two on each lip, as far as I have been able to ascertain. 
Rather fine and scanty hairs are spread over the foremost part of 
the body, especially in the æsophageal region. The cuticle is smooth 
and seems to be devoid of striæ. 
The buccal cavity is funnel-shaped with thickened chitin-in- 
tima but no teeth are found. At the level of the buccal cavity
