SUMMARY OF CURRENT RESEARCHES RELATING TO 
found, of tlie nine Gastropods only three have as yet had the species 
determined. A fine Pennatulid with a rich orange pigment insoluble 
in alcohol, was taken at about 200 fathoms ; several Umbellulse were 
dredged; a good series was obtained of Fldbellum japonicum ; to a large 
and interesting Foraminifer the name is given of Hormosina Bradyi. 
Freshwater Fauna of Iceland.* — MM. J. de Gueme and J. Richard 
report that M. Rabot, in his recent expedition to Iceland, added twenty- 
nine species to the freshwater fauna; of these, all of which are already

Protozoon ; some of the Crustacea were known from Arctic, and others 
from temperate waters. 
Invertebrate Fauna of Poland. f — Dr. J. Nusbaum reports on various 
Polish faunistic observations. H. Lindenfeld and J. Pietruszynski J

Aulostomum gulo, Hirudo medicinalis, Clepsine sexoculata, Cl. marginata, 
Cl. bioculata, Cl. polonica sp. n., Piscicola piscium, Cl. tesselata. The 
variations in colouring seem to have some relation to locality.
