CRUSTACEA COPEPODA. II. 4g 
Occurrence. — Not taken by the “Ingolf’. 
This species is only known from localities at West Greenland, and seems to be rather common 1n the 
anterior lower part of the branchial cavity of Phobetor ventralis (= tricuspis Reinh.). The Copenhagen Museum 
possesses old specimens from Godhavn (Olrik), besides a good number in all probability from Egedesminde 
(Mag. sc. M. Levinsen), and a couple of specimens from Jakobshavn (Traustedt). O. Fabricius had most prob- 
ably his specimens from Frederikshaab. 
Tanypleurus Stp. & Ltk. 
In some respects this genus, based on a single species, shows affinities to Chondracanthus, but it 
differs widely in some other features, especially in possessing a quite anomalous organ for fastening itself on 
the host. It may perhaps find a provisional place at the end of the present family.

The material enumerated below is only that on which the Danish authors quoted more than sixty 
years “ago established this curious form. As the specimens are still older and somewhat soft, 2 dissection of 
the front part of a specimen would probably not yield any real result, and without such special investigation 
I cannot add anything with certainty to the description of the authors.
