Additions and Corrections to the paper: On a 
new Grymnoblastic Hyclroicl (Ichthyocodium sarco- 
tretis) epizoic on a new Parasitic Copepod (Sarco - 
tretes scopeli) infesting Scopelus glacialis Khdt.

I am sorry to have made a wrong statement in the paper 
named above sajing on p. 3: “In the Davis Strait it (o: the Sar- 
cotretes ) seems not to occur; among some 330 specimens of Scop. 
glacialis collected by the “Tjalfe” W. of Greenland, between ca. 
63° and 71° Lat. N., none were found infested.” This is not true. 
A few days ago Mr. Ad. Jensen found some tubes which 
had been set apart from the material of Scopelus glacialis from 
the “Tjalfe-Expedition” handed over to me for examination. Evidently 
Mr. Jensen had forgotten the faet that he himself had observed 
the parasite and picked out the infested specimens of Scopelus, 
including them among the Crustaceans which were to be given to 
;he Division of Arthropods of our Museum. Thus I naturally 
Jould not find parasites in any of the ca. 330 Scopel. glacialis 
iaught between 63° and 71° Lat. N., every infested specimen 
laving been taken out beforehand, and I think I cannot be blamed 
or the error I am now going to correct. 
The tubes contained 9 Scopelus glacialis, from 20 to 52 mm. 
n length, each carrying an adult female of Sarcotretes scopeli ;
